#102 - Another Adventure with Brent

Happy November!

Autumnal change has shifted my activity patterns. Early October brought unusual rains and frigid temperatures to Cave Creek Canyon and I resigned myself that this year’s nightly road cruising was over. Nocturnal snakes became diurnal as the Arizona Sycamore leaves yellowed and the fading sun quickly brought chill. I began to spend my days hiking mountain trails not to look for reptiles and arachnids but rather reaching destination goals and exercising while taking in the fall colors in the Chiricahuas. But I also wanted to search for the autumn-breeding tarantulas of the region.

Brent Hendrixson was on yet another extended field research excursion as part of his sabbatical, and had been transversing the southwest in pursuit of tarantulas. With earlier trips focused on scorpions, he was now visiting localities of many of our American Aphonopelma tarantulas and photographing not only our theraphosid spider diversity, but also the breathtaking vistas throughout their range. I followed his progress knowing that he would make his way to my camp, and we would seek the elusive Chiricahua Mountain tarantula, and maybe sneak in some landscape photography.

Readers may recall that in late June I stumbled upon a tarantula burrow up canyon above the Southwestern Research Station and was fortunate enough to extract a very elusive spider (see blog entry #94 “An Endemic Tarantula”). This Aphonopelma chiricahua was a surprising reward on a very hot and dry June 21. You also might remember my #96, which told tales from Brent’s August visit with his summer Millsaps College course students and our trip to find another tarantula native to a Sky Island range, Aphonopelma peloncillo in the foothills of the Peloncillo Mountains. I would write up both experiences in an article for the British Tarantula Society entitled “American Mountain Endemics” (JACOBI, M. 2018. American Mountain Endemics. Journal of the British Tarantula Society 33(2): 10-16). You may download the article by clicking here.

Hopefully many of you have watched my video on Aphonopelma marxi, the namesake of the Sky Island diversity or Marxi group of U.S. tarantulas. If not, click here. This group of spiders is of particular interest to me as my passion is for the fauna and flora of our Madrean Sky Island ranges, many of which are part of the Coronado National Forest. However, the closest population of A. marxi to Cave Creek Canyon is in the Gila National Forest, north of Silver City, New Mexico. This is about a two hour drive northeast of my camp at the corral. There lies the Pinos Altos Range of the Mogollon Mountains near the Continental Divide.

During the drive up to the A. marxi site I had encountered a wandering mature male Aphonopelma hentzi just outside of Lordsburg, New Mexico. This is the United States’ most abundant and widespread tarantula and a native of the Great Plains and Chihuahuan Desert.

During a very recent run to Lordsburg for supplies I encountered three male A. hentzi, and the first one was very unusual. It was in great condition, which on October 21 is certainly not what you’d expect from a summer breeder that has wandered for months. Perhaps even more surprising was this spider’s location. I had never found one so far west. The two I would find on my return from Lordsburg were in the Animas Valley, east of the Peloncillo Mountains. This is where I would have expected to be the species’ westernmost limit in this area. But this guy was about one half mile from the Arizona border, west of Highway 80, between Portal, AZ and Rodeo, NM in the San Simon Valley. The other “desert” species of this area, including A. vorhiesi, A. gabeli and A. chalcodes, are also late spring through summer breeders, and those males have disappeared. Finding a “Texas Brown” tarantula so late in the year and so close to Arizona was very unexpected. In fact, the only Arizona records that Brent and his colleagues noted in their 2016 Aphonopelma revision were two females that Brent had found in Greenlee County, Arizona three miles west of the New Mexico border, about sixty miles north of my state line New Mexico male.

The mature males that interested me though, as the leaves of cottonwoods, sycamores and maples changed with the season, were a dwarf species from the desert grassland and a mountain endemic named for the Chiricahua Mountains. Aphonopelma parvum is a diminutive newly described species from southeastern Arizona and southwestern New Mexico that is typically active in November and December. From my home in Cave Creek Canyon the population of interest would be one along State Line Road between Portal and Rodeo. And, of course, Aphonopelma chiricahua was what I would expect to be active at a similar time in the mountains, and what would be my primary target.

As Brent spent October traveling from locality to locality - and species to species - west of me, I texted him images of males I found here. The first of interest was found on October 9 just after midday crossing the road 1.6 miles from my camp, just west of Portal. Air temperature was 62ºF and the elevation 4790 ft. I considered it Aphonopelma parvum due to its small size. After all, the specific epithet of that species means “very little”. However, it was somewhat in an odd area between where I have now found A. parvum and A. chiricahua. As it was missing a leg and was thereby less ‘photogenic’, I took the above image for size reference and released him rather than saving him for Brent’s eventual arrival back in the Chiricahuas.

On the morning of October 11 I found an even smaller male near the mouth of Cave Creek Canyon, at 4912 ft elevation, just one third of a mile down canyon from my camp. Freshly matured, this beautiful little boy was very black and had long fiery orange-red hairs on his abdomen. I didn’t record the air temperature just before 8:00 a.m. when I encountered him crossing the road, but reviewing weather data collected at the Southwestern Research Station shows that it was in the low 50s there five hundred feet higher so I expect it was in the high 50s at the entrance to the northeastern Chiricahuas. This male was collected for Brent Hendrixson’s research.

The next tarantula of note was discovered in the outdoor restroom building behind the Cave Creek Canyon Visitor Information Center (VIC). As I unlocked the men’s toilet on the morning of October 17, I found a small deceased tarantula that appeared to be an immature female. It also was collected for Brent. It was following yet another period of autumn rainfall here in the canyon and the temperature was quite chilly that morning.

On Monday morning (October 29) I drove up the mountain to hike the high elevation Crest Trail near 9000 ft. Brent had spent a few days in Phoenix and while I climbed the trail out of Rustler Park he began his five-hour drive toward Portal. The Chiricahuas had experienced several days of beautiful mild weather, with temperatures in the canyon below reaching 80ºF after fifty degree mornings, and it was reasonably warm and very sunny up among the peaks. Along my hike I saw at least fifty baby Slevin’s Bunch Grass Lizards (Sceloporus slevini) sunning themselves, a pair of Mountain Spiny Lizards (Sceloporus jarrovii) and, sadly, on the drive back down a dead-on-road (DOR) Twin-spotted Rattlesnake (Crotalus pricei). Also spotted were several Red-tailed Hawks, numerous Western Bluebirds and Yellow-eyed Juncos and many other montane birds.

I was back in the canyon by about 1pm and not too long after Brent pulled into the corral, already 8000 miles into this research road trip. On his drive south from the interstate (I-10) he had found a male Aphonopelma parvum near Granite Gap where Highway 80 passes through the Peloncillo Mountains into the San Simon Valley. After he settled in and we got caught up we decided our first adventure would be to drive out to State Line Road to a site where he had previously found A. parvum. This tiny species lives in burrows the size of a pea and they typically have excavated soil scattered to the side of the entrance.

In the video below you will see one of the females we extracted. Believe it or not, this was actually what Brent considered a “HUGE” female. We were able to find several of these tiny females in a short span, but were somewhat surprised that we didn’t find any males moving about or hiding in clumps of grass. We did, however, find a Desert Box Turtle as we were leaving. We then decided to drive back north toward Granite Gap to perhaps find a male where Brent had found one earlier. Only a handful of miles north, when we were near Rusty’s RV Ranch where I lived four months last year and the first month of this season, we found a male. The images following the video clip show the female and male of this little tarantula.

Tuesday October 30 Brent and I explored Rucker Canyon at the south end of the Chiricahua Mountains. I had never visited the area and was looking forward to seeing the “flatter” southern Chiris. After a pit stop farther south in Douglas, Arizona, we drove back up to Tex Canyon Road and west into Rucker Canyon. Brent wanted to search for a “small black tarantula” that a friend of his had reported finding in numbers while flipping rocks looking for reptiles. We flipped a lot of rocks over a couple of hours, but never saw a tarantula. However, we did find quite a number of black and red Phidippus jumping spiders (probably P. carneus), scorpions (Paravaejovis spinigerus) and centipedes. While I was sitting at a picnic table at Camp Rucker (Walnut Grove Campground) photographing two jumpers, Brent went to flip more rocks and returned with an absolutely huge jumping spider feeding on a grasshopper. The spider’s abdomen was already huge, but its gluttony apparently had no bounds. Brent was able to carry it to me on the stick where it was perched devouring the insect.

We left Rucker Canyon and found our way west and then north up the west side of the Chiricahuas and headed toward Chiricahua National Monument (CNM). Several days earlier CNM’s Facebook page had a video of their Visitor Center staff releasing a male tarantula that would be Aphonopelma chiricahua. We figured that a drive through the CNM would be worthwhile and then we would drive up Pinery Canyon to Onion Saddle and back down the other side (“my side”) of the range back into Cave Creek Canyon. Not long after we passed the entrance gate we saw a male on the road, which was fortuitous as he was the only spider we would see there. We continued to drive through CNM to Massai Point where I took some photographs and then, satisfied with finding a male of our target species, we began the climb up the northwest side of the Chiricahuas. As we ascended the rugged mountain road we came upon a rafter of about a dozen Gould’s Wild Turkey. I have seen many of them over the past few days, from canyon to peaks, on both sides of the mountains. Back at camp we went out to Vista Point for some twilight landscape photography.

Yesterday was Halloween and the last day of Brent’s visit. I had anticipated that we would search for A. chiricahua burrows, probably near where I had found that female in a burrow back on June 21. However, it is an extremely elusive species and Brent was discouraged by the dozen or so attempts he had made to find this species over the past decade. After being on the road staying in tent or hotel for a long stretch, he was also looking forward to getting home to Jackson, Mississippi. He decided not to spend the night and asked me what hike I would recommend. He wanted to hit the road by mid-afternoon and take a break from spider hunting by exploring one of the trails that I frequent. I suggested that we drive up to the top of the mountain back to Onion Saddle and then hike the Barfoot Lookout Trail. Brent had been up to the top before and we drove up and over Onion Saddle the previous day, but he had never seen Barfoot or Rustler Park. After four or five days of very mild “Indian Summer” weather, it was colder Halloween morning and when we got up over 7000 ft it was cloudy and I worried that the amazing views we would have from the montane trails would be obscured by the fog. However, after driving into Rustler Park and showing him the area where our hiking club had encountered a tarantula at over 8500 ft. ten days earlier, and then driving to Barfoot Park and giving him a tour there, the cloud cover was parting a bit. Although it was a crisp 40ºF there at 8400 ft. and we were both wearing shorts, we at least had vests or flannel shirts and decided to stick to hiking the Lookout Trail. After our hike we drove down the mountain and before we descended to Onion Saddle Brent shouted for me to stop. Even though it was pretty cold I had been scanning the road for snakes, as I had seen that dead-on-road Twin-spotted Rattlesnake two days earlier. But before he jumped out of my truck Brent said, “I think I saw a tarantula”. Sure enough, there in the road was an adult male Aphonopelma chiricahua. It was not even half the size of the one we found in CNM the day before!

It is not uncommon for high elevation populations of animals to be considerably smaller, and we discussed the miniaturization of species with altitude. I suggested we pull off the road and walk around a bit and see if we found any other spiders. Brent began flipping roadside rocks and I walked back up the road looking in the ground litter on each side of the road for burrows. After a short period of time I called out to Brent that I had found another male! This one was curled up on top of a grass tussock and was in even better condition than the male Brent fortunately saw on the road. He also was very small - perhaps an inch and a half in diagonal legspan. As I showed Brent where I found him I began to closely examine a variety of wispy grass that covered much of the road shoulder. Before long I had found two small holes that weren’t much larger in diameter than the Aphonopelma parvum holes we had extracted females from two days earlier. They weren’t covered with silk and I wasn’t initially certain they would be tarantula burrows, but they were perfectly round and very clean and I soon became hopeful. Both holes were partially obscured in the middle of a patch of this fine grass. Brent began to flood the burrow and we were greeted by the forelegs of a tarantula! He poured a little more water and as it rose again and protruded from the burrow mouth a bit more, Brent used his other hand to scoop beneath the spider with a small trowel and our gorgeous prize, a surprisingly small adult female A. chiricahua, was out in the open. Below she is in all her glory, photographed later on my camp’s picnic table. After the image is another short video clip of Brent handling the spider in the field.

The second burrow I discovered was also occupied by A. chiricahua. It was a smaller immature spider. So Brent’s ‘day off’ from searching for tarantulas suddenly had - so far - resulted in four specimens of the one species to elude him for some time. To quote his social media post when he posted his own photograph of this beautiful female: “Long story short: this was the find of a lifetime! I have spent more than a decade looking for this incredible spider and TODAY was the day! I present to you an adult female Aphonopelma chiricahua from Cochise County, Arizona. Many thanks to @jacobipix for finding the burrow and giving me a place to crash for a few days!”

IMG_2845.JPG

Brent now had three males (two little guys from our high elevation ‘hotspot’ and the much larger male from CNM), one mature ‘high altitude’ female and a bonus immature. But we weren’t done. After returning down to my camp (after passing a troop of eight White-nosed Coati), I needed to drop something off at the post office so we drove into Portal and very close to where I had found the little male back on October 11 we found yet another male!

Today November begins and after training a new VIC host the next two days I will only have a few Saturdays remain as a VIC host. I’ll be staying until the end of the month, but have plenty of free time and also time to do some other non-hosting projects at the VIC. My tentative plan is to put winterize the Wheelhouse on November 30 and move it to storage at Rusty’s RV Ranch. Brent intends to fly back to Arizona for the first week of December to look for a couple of other late fall-winter active Aphonopelma (A. paloma, A. superstitionense) and we discussed me joining him. Then I will return to Chicagoland for a few weeks prior to my January Malaysia trip. And then perhaps back to Cave Creek Canyon in March?

#98 - Another Visit

I hadn't seen Chad Campbell in far too long. I tend to lose touch with people even in the best of times, and heading out to live on the road at the beginning of 2017 didn't lessen that propensity. Still, more sociable people can always reach out to solitary me, so I am never willing to take all the blame. And Chad did just that with an unexpected text asking whether I'd pick him up in Phoenix if he landed there. I have no clue how long it had been since we'd had any contact other than liking each other's Instagram posts, but it didn't affect my reply. I told him Tucson or El Paso were cool as they are 2.5 and 3 hours away, respectively, but Phoenix (5 hours) was a no.

There is a very, very short list of people that have an open invitation to visit me and Chad certainly was on it, but after a few casual mentions last year to a few of the honorees of that mental list, I really didn't talk to anyone at all this year. As you read in the previous blog entry, my bonus dad Joel just visited and we had arranged that trip even before I left his house the day after his birthday in mid-April. He was set to spend my birthday here with me the first week of August and, other than visits by my arachnologist friend Brent Hendrixson, I didn't anticipate any other visitors. But Chad was itching to return to Arizona after his previous visits to Tucson for American Tarantula Society conferences that have since fizzled out, and without much hesitation he bought his plane tickets and I scrambled to switch with other volunteers to free up my schedule not one week after I had taken an entire week off from the Cave Creek Canyon Visitor Center in the northeastern Chiricahua Mountains to spend all my time with Joel.

IMG_2317.jpg

Jump ahead to another trip to Tucson the night before picking up a guest. Again I wanted to road cruise for sidewinder rattlesnakes, and this time a guy I met through Instagram had recommended a road west of the one I had cruised the night before I picked up Joel. Heading out past the Old Sasco Ruins through rugged Sonoran Desert into a stormy dusk, I truly felt in the middle of nowhere. Just off the interstate the town of Red Rock, Arizona is new modern suburbia, but quickly the cookie cutter adobe family homes give way to sandy desert grassland scrub. Then, out of nowhere, I came upon a massive feed lot and sights and smells that will turn you off of beef for life. Thousands upon thousands of cattle stood shoulder to shoulder and I looked away and picked up the pace before the strong odor became too much. The pavement then ended and the dirt road soon disappeared into saguaros reaching toward the purplish gloomy sky and I was swallowed by the desert. I was glad there was still light so I could read the warning signs about road closures, flash flooding, federal agents and more, and I drove deep into the desert between the mountains and back out to learn the area before darkness. The road had many steep dips that recent rains had filled with water and rocks and several crossings were of great concern. One held as much water as I'd ever want to drive my truck through (and I did it four times) and another was very wet but also very rough with big rocks that had washed into the crossing. There were many "stream crossings" and quite a bit of rough road. That night I tested my truck more than any other.

Flashing forward once more, the next morning I was back at Tucson International Airport early enough for a local beer. As I finished up and started towards Chad's arrival, he texted me that he was already outside having a cigarette, his very short flight from Phoenix arrived early. His first request, even before he had left Minneapolis, was that we head from the airport directly to In 'N Out Burger, the legendary West Coast fast food icon. Then it was off to a giant liquor store I had scouted the day before for a connoisseur's collection of West Coast India Pale Ales for Chad, plus a small selection of lagers for me including not only Grand Canyon pilsner but my beloved Imperial from Costa Rica. Then we headed east to Willcox for groceries and on to an area known to contain two tarantula species, which Chad had explored a couple years prior during one of his Tucson visits. Rain shortened our time - and unsuccessful search - at the tarantula site, and we pushed on back here to Cave Creek Canyon. Chad would be the first visitor to actually bunk in my Wheelhouse and we had groceries and beer to stow and food to grill. But first Chad unpacked some very generous birthday gifts he had hauled all the way from Minneapolis, incurring overweight bag charges in the process in order to bring me some special beverages and a coffee cup. There were two imperial stouts and a giant Ziploc bag containing eight pint cans of one of my personal favorites brewed in Minneapolis - Indeed Brewing Company's Mexican Honey Imperial Lager.

Chad's visit was only from midday Friday to midday Tuesday so we were working with limited time. Chad wanted to see tarantulas and rattlesnakes most and that he did. Saturday we made a trip into New Mexico and down into the Peloncillo Mountains to search for the tarantula I had pursued with Brent and his students only a couple weeks earlier. Successful in finding that special American spider again, I then took him to the scorpion site where I had taken four of Brent's students.

Chad had only seen Western Diamondback Rattlesnakes before, and he added quite a few more of those to his life list, plus many more first-time ('lifer') Mohave Rattlesnakes and one special encounter with the third species of our trip, my favorite, the Black-tailed Rattlesnake. And he found it himself! I had taken up South Fork Road and South Fork Trail in search of the Elegant Trogon, the rare bird people come from around the world to see here, and - though we didn't find the trogon - during a search of a cabin for jumping spiders Chad found a young blacktail a few feet off the ground, nestled in the rock exterior rock wall. The snake didn't move as we took in situ photos of how we found it, including the smartphone image to the left, and then Chad returned to my truck which was parked nearby to get the rest of our needed camera gear and one of my snake hooks. Black-tails are usually placid rattlesnakes and this yearling snake certainly was very cooperative as I then moved it onto a nearby group of flat rocks so that we could photograph it further.

Another snake that Chad had repeatedly mentioned that he was hoping to see was a kingsnake. We have two here, the tri-colored Mountain King here in the mountains, and the Desert Kingsnake in the foothills and surrounding desert. Both can be very elusive so it was quite a thrill when one night's road cruising, the night we went down to the Peloncillos, included this beautiful black-hooded king.

Chad and I share a love of jumping spiders and he has become quite accomplished at doing true single-exposure macrophotography of jumpers using the same 1:1 100mm Tokina macro lens I use plus a 2.5X magnifier and a special light set-up. We were fortunate to find quite a few special jumping spiders during his visit. One was at almost 8400 ft elevation at Barfoot Park, and we also found cool jumpers right at my camp at the corral and a number of photo sessions took place on my picnic table.

On Chad's last night here, we went for another dinner at Portal Cafe and then Chad chose to return to the corral to enjoy some beer, conversation and image processing over another night of road cruising for snakes. But on the way back into the canyon we were destined for one more snake during his visit, which he called his "snake-cap", and it was a special one at that.

I don't know where I'll be next year, but if I am in the Chiricahuas I am hoping Chad will return and bring his girlfriend April with. We even talked about getting a small gathering of mutual friends together for more herping and spidering fun and more connoisseur brews and good food.

#97 - 54 - Adventures with Yet Another

MJ_Hiker.jpg

2300 miles, 25 or so live rattlesnakes, 54 years. One amazing visit.

Three French hens, two turtle doves. And a trogon in a sycamore tree.

Those are just few of the numbers from my birthday week, which began two days before the 5th when I drove to Tucson to look for sidewinder rattlesnakes that Friday night before picking up my stepdad Joel from the airport midday Saturday.

2.5 hours to Tucson, an oil change, Wing Stop lunch and an afternoon escape-the-heat matinee of Mission Impossible - Fallout later, I was at the Motel 6 North Tucson.

That night I found my lifer Sonoran Desert Sidewinder. The next morning another lifer - this time a Sonoran Desert Tortoise.

Then it was the airport and a scenic drive up the Catalina Mountains, followed by some Tucson shopping, groceries in Willcox and a dusk check-in for Joel at Rusty's RV Ranch. A short time later it was Joel's lifer rattlesnake as I spotted a Western Diamondback on the roadside only five minutes after leaving Rusty's to take him into the Chiricahuas for the first time. In the excitement I shooed it off the highway without capturing an image, but Joel got the thrill of seeing me move it from the road and see it slither into the desertscrub. As we entered Cave Creek Canyon it was rattlesnake number 2, a Western Black-tailed that a couple of guys had discovered. We asked if we could join them so Joel could see my favorite rattlesnake. It wasn't necessary as he'd see a few more during the adventures to come.

My diary will get fuzzy here as we did so much it would be impossible for me to recount it all chronologically without overlooking something. The snakes are a blur. So I'll forge ahead to the next day - Sunday the 5th, my 54th birthday. I had something different planned and our final destination was the wild west town of Tombstone, Arizona. First there was a stop in Douglas to see the wall between that city in extreme southeastern Arizona and Agua Prieta, Sonora, Mexico on the other side. Then we headed west along the wall, on to Bisbee for coffee and, finally, were walking the dusty cowboy streets of Tombstone. A beer at Doc Holliday's Saloon, some shopping and then lunch at Big Nose Kate's Saloon and before long we were back in Bisbee to have a beer at Old Bisbee Brewing Company. Back in the Chiricahuas for dinner time we grilled up steaks at my corral.

Road cruising followed, as it did every night, and Joel saw Diamondbacks and the deadly Mohave Rattlesnake, which would be the most frequently encountered snake over the week and two dozen rattlesnake engagements. In fact, we saw the largest Mohave I've seen one night in a very unexpected location. But of all the snakes the one we both will remember most is a big beauty of a Western Black-tailed that was crossing the primitive mountain road at 7500 feet elevation in the early afternoon. My goal for the week was always to get a photo of Joel with a rattlesnake. I didn't want him to get too close, but I think this image speaks a thousand words.

This beast was a spectacular example of the species that is my favorite rattlesnake both for its beauty, habitat and fairly gentle disposition. When a carload of birders descended the mountain road I had already moved it off the road, but I asked them if they wanted to stop for photos. It was a rare moment of wanting to share the joy of the experience and the majesty of the snake.

Other adventures included a trip up the mountain road over the top of the mountain to descend through Pinery Canyon to the northwestern side of the range for a visit to the Chiricahua National Monument. This special place has incredible rock formations - pinnacles, hoodoos, balancing rocks. We took in views like the one below at Massai Point, but then would take perhaps our most arduous hike of the week when we summited Sugarloaf Mountain.

While we were at Massai Joel had asked what the structure atop a distant peak was. I had to look at it through binoculars and then I looked at the map and figured it out. He had no idea what was in store for him when I drove to the parking lot trailhead.

The trail was only one mile or so each way, but it climbed about 500 feet to an elevation of 7400 ft and was often steep and slippery.

Another adventure was our first birding trip. I wanted Joel to see the Elegant Trogon, the bird people come here from around the world to see, the Mexican bird that perhaps numbers only 60 in the United States. We parked in a prime area and I got out and only moments later was pointing out the dazzling male above us. I hadn't walked six steps. Good fortune smiled on us.

Each day we hiked, dined, road cruised. We were constantly on the move except one afternoon in Rusty's swim spa relaxing with a cold cerveza.

IMG_2244.jpg

Snakes, birds, snakes, snakes. Tarantulas, vinegaroons, scorpions. More hikes. Each day was filled with activity and as the week began to wind down I asked Joel if he was interested in a road trip. I thought perhaps he'd want to see somewhere else in the southwest and we decided to limit it to a three hour drive. I mentioned a few options, but the one that immediately was of interest was Gila Cliff Dwellings National Monument north of Silver City, New Mexico. I had visited the Gila National Forest in the region a few times last year, but had never gone to the Cliff Dwellings. It was pretty spectacular. I admittedly am not one for history and historical sites, but at the Gila Cliff Dwellings National Monument you can actually enter the cliff dwellings unguided and see where Mogollons lived for twenty years or so in the late 1200's. It was certainly worth the trip and the winding and climbing scenic mountain drive there and back added to the experience.

It was an action packed week that left me exhausted. Saturday morning I picked Joel up one last time at Rusty's and we made the 150 mile trip to Tucson Airport. Then I turned around and headed home with a brief stop in Willcox for a few groceries and some lunch. As I type this Monday afternoon I am preparing to head to Tucson again Thursday. I will once again spend an evening looking for sidewinder rattlesnakes and then Friday morning pick up my buddy Chad at the airport for his five day visit. I'll close now leaving y'all with a short video of me wrangling one of the beautiful black-tailed rattlesnakes Joel got to see during visit. I don't usually have a cameraman so it was nice to be on the other side of the lens and get some memories captured. Below the video I'll post a list of just some of the animals Joel got to see during his week.

#94 - An Endemic Tarantula

For the ten years prior to beginning my road odyssey last year, most of my travel had been to exotic locales in search of tarantulas. Costa Rica, Suriname, Sri Lanka. These were destinations chosen for tarantula field work. Even Malaysian holidays had a primary focus on tarantula hunting. Even going back over thirty years, my road trips to Texas had an arachnological mission.

True, snakes and other reptiles were my primary distraction and deviation, and more than once on that first Costa Rican adventure in 2006, my mate and field trip leader Andrew Smith tried to rein in my desire to chase things that slither with commands of "Tarantulas, Michael, tarantulas!". Now an avid birder and wildlife photographer who often has mammals or other charismatic megafauna in the lens, I'd like to think that I was always a generalist naturalist. I love nature in all its forms. As enthralled as I was by the gorgeous red-legged tarantula (Megaphobema mesomelas) in Costa Rica, the world's largest spider in Suriname (Theraphosa blondi) or my beloved tiger spiders (Poecilotheria sp., ornamental tarantulas) in Sri Lanka, along those journeys Costa Rican hummingbirds enchanted, Surinamese labaria vipers thrilled and a fortunate sighting of a leopard in Sri Lanka amazed. Do I even need to mention orangutans and tree vipers in Borneo, or dusky leaf monkeys and hornbills in Malaysia?

Still, my tarantula-obsessed friends have wondered why my Instagram feed and blog entries have neglected the tarantula. Andrew has emailed me inquiring as to whether I do any tarantula hunting. In truth, last year I paid more attention to scorpions than tarantulas, and much more time was spent in pursuit of rattlesnakes. This year I am all over the place, chasing microfauna like robber and owl flies one moment and bears, bobcats and even the mountain lion the next. For the past two years, with only a few exceptions like the Rio Grande Gold Tarantula (Aphonopelma moderatum) in Texas or the beautiful Aphonopelma marxi tarantula from north of Silver City, New Mexico, both of which were female spiders I observed in burrows, the only tarantulas I have encountered have been wandering mature males found here in southeastern Arizona and southwestern New Mexico while out road-cruising for snakes.

It isn't that I have forgotten tarantulas. It is just that, firstly, this rugged area frustrates tarantula hunters and, secondly, I have many interests. Searching grasslands and desert scrub for burrows for the more abundant species in this region is hard work, so I guess an argument could be made for a third factor: laziness. Admittedly, a fourth reason could be collector bias for sexy spiders. When you've seen stunning tarantulas like Megaphobema mesomelas in Costa Rica and Poecilotheria subfusca in Sri Lanka, the local "brown jobs" like the local Aphonopelma gabeli and A. vorhiesi honestly don't have the same allure.

But let's get back to the first reason. My experience tarantula hunting in this region is limited, but my friend, arachnologist Dr. Brent Hendrixson, knows the tarantulas of the American Southwest better than anyone and has spent years and years searching for them. He has told me repeatedly that they can be very difficult to find. Many make their burrows beneath rocks or in scrapes where flipping rock after rock becomes the search method. Did I mention my laziness? At night I'd rather road cruise for snakes or black light for scorpions (the former enhanced by air conditioning and music; the latter makes finding scorpions rather effortless), and during the blazing heat of the day I can't bring myself to walk alone through the desert turning rocks.

However, there is one tarantula in the region that began to intrigue me. By now every reader should know of my deep love for the Chiricahua Mountains and that this year I am actually living right in the mountain range's Cave Creek Canyon. I have spent little time out in the surrounding flatlands. Most of my time is spent at 5000' or above, from the pine-oak woodlands of the rocky canyons and adjacent riparian zones up to the coniferous forests at 7500' and higher. And there is a newly described species of tarantula that lives in the Chiricahuas from 5000-8000'.

Aphonopelma chiricahua was described in 2016 by Brent and his two co-authors in a complete revision of the American species in the genus (all U.S. tarantulas belong to the genus Aphonopelma, but the genus reaches Central America). Their paper created many synonymies drastically reducing the number of species in the United States (currently 29), but it also established a number of new species endemic to specific localities (primarily Sky Islands) including Aphonopelma chiricahua, which occurs only in pine-oak woodland and mixed conifer forests here in the Chiricahuas.

Last week I encountered my first wandering males of the season while driving Portal Road at night. I was returning to Cave Creek Canyon from road-cruising out in the desert and found two males - the first just west of Portal and the second a little over a mile later closer to the entrance to the canyon. They looked freshly molted and I sent images to Brent for identification help. Mature male A. gabeli and A. vorhiesi look very similar, but it was the time of year that made him think it was probable they were the former species, which matures and breeds earlier than the late summer breeding A. vorhiesi. I had found plenty of both last year, and seeing my first males of the year stirred a desire to find something else. Yes, to tarantula hunt once more! Brent was on the road doing his own tarantula hunting in New Mexico and Texas during our conversations, and while I waited for replies I spent a good deal of time re-reading pertinent sections of the 340 page generic revision he co-authored. It reminded me that the "Arizona blonde" tarantula A. chalcodes is even found in this region (Brent found a male on the road to nearby Paradise that I drive frequently), which made me further bemoan how unlikely it was for me to find a female of any species in its burrow. But what really enticed me was the section on A. chiricahua.

The endemic species in the Chiris was described from only a handful of specimens. The male holotype (a single type specimen upon which the description and name of a new species is based) was actually caught by a retired biologist who is now an area realtor and is well-known to me. That was surprise number one. This male was found at 5083 ft. elevation on the road only a mile up canyon from the corral where my Wheelhouse is camped. Surprise 2. I then learned that the female paratype (additional specimens in the type series, other than holotype, used to describe a species) was from the area surrounding the Southwestern Research Station of the American Museum of Natural History (SWRS). It was collected at 5436 ft. and had been preserved for years at Auburn University in Alabama. The species description of Aphonopelma chiricahua in Hamilton, Hendrixson & Bond, 2016 was accompanied by no photo of a live female. An additional male was designated as paratype and, in total, eight specimens were examined for the species description within the Aphonopelma revision/monograph. The paratype female was the only female. The highest elevation male came from 8432 ft. near Rustler Park. 

Surprise #3 was that this species breeds in autumn. That meant that I wasn't going to come across wandering males this summer. My personal correspondence with Brent made me aware that he knows of females being seen on the roads during summer, presumably flushed out of their burrows during the summer monsoon rains. I began to hope I would be lucky enough to find one.

Jump ahead to this past Thursday, better known as the first day of summer. My previous blog entry recounted my experience that morning observing a behemoth of a black bear on the road just up canyon from the corral. What happened after the bear sighting is what concerns us here. As I have mentioned many times in many blog entries, I often don't know where I am going until I get there. I don't really plan my free days in advance. My truck is guided by whimsy. I could have easily gone hiking up on the Basin Trail in search of snakes or just walked my well-worn path on South Fork looking for Elegant Trogons and other birds. But I passed South Fork Road and then didn't turn off the forest road at the research station as I would have for the Basin Trail, Ash Spring or other popular destinations where I often hike. I decided to, for the countless time, to hunt an area above the research station for Rock Rattlesnakes. I have spent many hours in this prime location without success, but that doesn't prevent me from climbing the steep rocky hillside and shining my flashlight into likely crevices among boulder piles yet again. And this time it was in the back of my head that the location center for Aphonopelma chiricahua was also here. As the description reads, "Most specimens in natural history collections have been collected near the AMNH's Southwest(ern) Research Station".

The rock rattlesnake site is based on information from a friend who was part of a group that observed three within 30 yards of each other there during last year's SWRS field herpetology course. It is up a hillside adjacent to the SWRS, but accessed from about a mile up the road. That's about as specific as I choose to be. The steep slope has rock slides and boulder piles and is pine-oak woodland with pinyon pine, scrub oak, alligator juniper, Palmer's agave, prickly pear cactus, mountain yucca and numerous grasses, etc. After ascending to the area that looks like prime rock rattlesnake habitat and scouring the rocky terrain, I decided to continue to crest the hill and entered a grassy area at the top. I continued to hike down canyon from the highest elevation, which means towards the SWRS. I was wondering if I would find a vista where I could see the research station below. Most of my snake searching had been concentrated to a very rocky area about half the size of a football field and I have made a handful of visits this year to combine with dozens and dozens last year. This was, however, the first time I had gone all the way to the top, which reaches almost 5800 ft. above sea level and has extensive grassy flat areas. I found a large area cleared by ants and stopped to enjoy the breathtaking views of the canyon and the valley below. My mind turned to spiders and I began criss-crossing the top of the hill looking for any small creature to photograph. My camera had my macro lens and ring flash on it and I flipped some rocks looking for a subject. Always hoping for a snake or lizard, any beetle, bug or spider would do.

I hadn't hiked with my attnetion focused on the ground for more than a few minutes when I stopped in astonishment. There in my path on what seemed like a well-worn animal trail was a perfect tarantula burrow covered in silk. The species description of A. chiricahua is based on limited natural history information. It states, "Very little is known about the natural history of this elusive species. No burrows or shelters have been observed but these spiders probably seek refuge under rocks and rarely place silk around their burrow entrances". Elusive. Little known. I was very excited as I realized that this must be the spider and here I had found a perfect burrow near the type locality. The morning sun was rising fast and with a high temperature of 100F predicted I was hot, sweaty and tired from my climb. But I forgot all as I dropped to my knees and photographed the "textbook" silk-covered burrow. Perhaps the "rarely place silk" was presumptuous.

  Only a tarantula burrow looks like this. There was no question what lived inside.

There are several ways to coax a tarantula from its burrow: flushing, tickling and digging. The latter is to be avoided as the tarantula can be injured or trapped, and it is destructive to the habitat. Furthermore, if you just want to photograph and release you are left to rebuild the retreat and it will always yield a very unsatisfactory result for the spider and alters the habitat. Arachnologists simply cannot dig perfectly round tunnels into the earth terminating in a chamber. Flushing is an easy and non-destructive means that works remarkably well in arid habitat. In essence you are simulating a flash flood and the tarantula will instinctively flee its tunnel and chamber rather than risk drowning inside. When tarantula hunting in the desert one normally carries jugs of water for this purpose. Hiking up the hillside I only had one 20 oz. water bottle and I had already drank half of it. We'll come back to "tickling" in a moment. First, we have to use a twig to brush away the silk layer the tarantula created to shade its retreat and deter pests like ants from house-crashing.

  Tarantulas dig their own burrows and many are so perfectly round it is as if they were drilled by a coring machine.

With the silk removed and the hole once again photographed (yes, we tarantula hunters have far too many images of seemingly empty holes in the ground), I didn't give a moment's thought to my hydration despite my thirst and the heat. I began to pour the last ten ounces of berry flavored electrolyte-enhanced water in my possession down the hole. The orangish-brown furry legs that came forward put a big dorky smile on my face.

Alas, ten ounces hardly simulates monsoon rain flash flooding. The handsome rusty-brown tarantula came to see the light of day and its trespasser, but then just as swiftly retreated to darkness. I was out of flushing water and also now had nothing to quench my thirst. Two more full water bottles and backup gallon jugs were in my truck way down the hillside. So it was time to practice the art of tickling. But first, let's look at the habitat where the spider and I were spending the morning of the first day of summer.

  In the center foreground you will see my walking stick inserted in the burrow when I returned later that evening to take additional photographs and record GPS coordinates lost during the excitement.

Tickling involves using anything from a blade of grass to a twig to entice the tarantula to the mouth of its burrow. There are various techniques used that range from dexterous finesse to a slightly more aggressive approach. Each of the gents I have pursued tarantulas with in the field has a personal touch. I admittedly lean toward the aggressive. Tickling can simulate a prey item and, in fact, tarantulas will often grab the twig with their jaws/fangs and can almost be tugged out of the hole. Tickling is usually accompanied by using the free hand to shade the hole so sunlight (or flashlight at night) is less likely to spook the spider. The finesse method employs brushing the forelegs and/or gently tapping the tunnel to elicit a feeding response. This brings the tarantula close to the opening, and typically requires many tries. My impatience usually gets the best of me and I tend to let the length of grass or twig go over or beside the tarantula when the opportunity arises so I can smack its little behind and encourage it to come out post haste. Overheated and without water, with the sun and temperature climbing, I relied more on the aggressive approach. I couldn't shade the hole with my free hand because I was trying to film video of the tickling with my iPhone, nine second of which can be seen below. With the glare of the sun and salty sweat running into my eyes preventing me from really seeing what was on the screen, and my heart racing with the excitement of finding this species in its burrow, the result wasn't great. 

I set down my phone for my final "tickle" and the spider came out. It was missing a leg and I couldn't help but wonder if I caused that during my sun-blinded, overly excited, aggressive tickle. Tarantulas readily autonomize their legs, which will regenerate during next molt. Within two molts the replacement leg will look like the original. With the spider out I then had to quickly decide what to do. I flattened my hand over the burrow opening to prevent reentry while I collected my thoughts. Normally I collect nothing. I might "temporarily restrain" for a later photo shoot in better conditions and later release in exact location, but I quickly realized that this specimen would be important to Brent as a research specimen. He will be visiting the Chiricahuas next month so he can take it for his own photo session. I know full well that it is likely he will pickle it for science, but I try not to dwell on that. I collected scorpions for him last year, and I resigned myself that this tarantula would be a gift to him. I would keep it alive until he and his summer field arachnology students arrive in the Chiricahuas. But, like I said, I don't collect and therefore I had no container. I had my camera, my iPhone, one - now very empty - water bottle, and my walking stick. Thankfully, my water bottle has a wide mouth lid and I put the tarantula inside. It was getting hot quickly so I hurriedly used my Gaia GPS app to find the waypoint and scrambled down the hill before the stainless steel bottle became too hot for the spider within. It wasn't until later that I discovered that in all the excitement I hadn't actually saved the waypoint. I had descended the hillside with a spider without exact location and elevation. I also descended rapidly through an unfamiliar area and wasn't sure where exactly I had been. Still, I'd have to hope I could find the burrow at a later date.

Back at my truck I grabbed a small box waiting for the trash and filled it with dirt and leaf litter from the area. I had one vacant custom tarantula home back at the Wheelhouse that was currently storing millet spray for my parrot that I would use to create a terrarium for the spider. Then I drove straight back to the corral to take some photos and build its new home. Back to WiFi, I posted the above video to my Instagram story and texted Brent. I was one happy tarantula hunter. Later that same evening, after the 100F had dropped to 90F, I returned to the hillside and tried to retrace my steps after climbing back up the rocky slope (again seeing no freaking rock rattlesnakes). I wandered a bit aimlessly for about thirty minutes once I reached the summit until I remembered the small dead tree near the burrow. It can be seen just to the left of my walking stick in the above habitat photo. Once I found that landmark, the burrow was easy to find and I was able to record the precise location. The burrow was at 5645 ft. elevation. As the crow flies it was just under three miles up canyon from my camp, almost directly north of the west side of the complex that is the AMNH Southwestern Research Station. And now I am on a quest for more. And a cricket or two to feed my new roommate ...

#77 - "Wet Week" - Rodeo, New Mexico

I have now been back in Rodeo/Portal for a little over week and the rains have been surprising. The monsoons are in full force and not a day has gone by without rainfall. When the desert where I am camped is dry, a look toward the surrounding mountains often reveals low dark, clouds and rains in the distance. At night the roads are full of toads - spadefoots, greens and even a few big river toads.

Here in the San Simon Valley, where the Sonoran and Chihuahan deserts converge, the landscape has changed. But the monsoon rains are prevalent throughout the southwest, and my friend Brent and his seven students had encountered wet conditions west in the Tucson area and came east to New Mexico a day a head of schedule. That was good as I had mistakenly thought the 40th International Herpetological Symposium (IHS) started one day later. Due to the Millsaps College (Jackson, MS) crew's arrival on Tuesday, I was able to spend that afternoon and evening with them in the Chiricahuas. They camped in Sunny Flat Campground in the Chiri's Cave Creek Canyon and when I met up with them they were flipping rocks in search of the giant vinegaroon or whipscorpion (Mastigoproctus giganteus). As I said hello to Brent and his students Aaron and Ashley who I had met in May and was introduced to the rest of the Field Arachnology Course students, many of them already had vinegaroons climbing on their arms.

After the students were done playing with the vinegaroons I followed the group back to their campsite. Not long after the skies opened up and we sought shelter under the ramada of a neighboring campsite. We had coolers of beer and I hung out with them in the beautiful mountains into the night.

Wednesday I decided that I would join them for their trip two hours northeast to the Gila National Forest. They would camp at Cherry Creek, which is at 6800' elevation in the mixed confifer forest about fifteen miles north of Silver City. Wednesday night the IHS would begin with an icebreaker, but I decided to skip that in favor of spending more time with the Millsaps crew who intended to search for the beautiful resident tarantula species, Aphopelma marxi. Brent also had some specimens of scorpion and tarantula from Utah and Arizona that I wanted to photograph. So I invited a few of the students to ride in my truck and Lillian-Lee, Frances, Niki rode with me as our group stopped for breakfast in Lordsburg, groceries and laundromat in Silver City and then arrived at Cherry Creek. As they began to set up camp, Brent and I walked across the road to an embankment where he had found Aphonopelma marxi burrows in previous years and within a short time I found a perfect silk-covered burrow and shined my flashlight beam inside to reveal a pretty female tarantula. The students were called over and Niki used my water jug to simulate flooding and coax the tarantula to emerge.

I originally thought I might leave early enough to drive back in time for the IHS icebreaker, but I stayed until just before dusk and drove back exhausted. I had hoped to road cruise some of the northern roads, but it was still light as I made it back to Silver City and started down the major highway toward Lordsburg. The four-lane highway was surprisingly deserted, but I was too tired to drive very slowly. Still, when it narrowed to two lanes I encountered a Prairie Rattlesnake on the road. It was a fiesty little bugger and it wasn't until the next day when I saw my photographs that I noticed a bit of blood on it that was likely from a glancing strike of a car tire.

I stopped for fuel in Lordsburg and by the time I got on the interstate (I-10) rain had begun to fall. I was unhappy about that as I really hoped to find rattlesnakes on Highway 80 between the interstate and camp. This 25-mile stretch, which passes through the Peloncillo Mountains at Granite Gap, is home to natural intergrades of Prairie and Mohave rattlesnakes as well as pure bloodlines of each. But the torrential rains had made the road a toad wonderland. My slow driving wasn't to look for snakes on the road and beside it, the pace was instead necessary to weave through the spadefoot toads enjoying the shower. I photographed several as they are highly variable, but then was overwhelmed by their abundance and just carefully drove the remaining miles hoping to squish as few as possible.

Thursday morning I arrived at the Chircicahua Desert Museum's Geronimo Event Center for the continental breakfast that would precede each morning's lectures. The lectures kicked off with a herpetologist associated with the Southwestern Research Station of the American Museum of Natural History, which I have previously mentioned is located here in the Chiricahua Mountains. His presentation was on my favorite group of lizards, the horned lizards of the genus Phrynosoma. Thursday, Friday and Saturday I attended most of the lectures, returning to camp during the two-hour lunch break each day. About 180 people were in attendance and I was surprised at how well the event had held up over the years. A little online research informed me that the last IHS I had attended was 26 years earlier, in Seattle in 1991. My old friend Scott Michaels and I had attended about a half dozen between the mid-80s and that 1991 trip.

The 40th IHS concluded Saturday night with a banquet featuring a steak dinner and cheesecake dessert. An old friend of mine from reptile shows in the Pacific Northwest, Giovanni Faglioli of The Bean Farm, walked throughout the crowd pouring tequila shots from a giant bottle. The banquet lecture was delivered by celebrity herpetologist Mark O'Shea and it was educational, entertaining and brilliant. His red hair now long and grey, the diminutive Brit regaled us with his reptile stories from his childhood in England's Midlands to the present. His stories included a number of bites from venomous snakes and chronicled his annual expeditions from his first visit to Florida through his trips around the world on research teams and film projects for Discovery Channel, National Geographic and his O'Shea's Big Adventure.

This Wednesday evening many of the people who attended the IHS including Mark O'Shea and many new arrivals will convene back at the Geronimo Event Center for the icebreaker that kicks off the first Biology of Snakes Conference. Yesterday was a day of rest for me, but I plan to spend the next two days before that conference begins doing some hiking in the mountains. Legendary snake man and photographer Bill Love told me about a spot for Twin-spotted Rattlesnakes and I am eager to trek up to high elevation in pursuit. However, any field hunts whether hiking or road cruising are at the mercy of the monsoon rains that have resulted in a very wet week.

Cheers, MJ
