I can’t remember in what book I first saw a picture (a colored drawing, not a photo) of a European four-lined rat snake, but I do remember that I was still in elementary school when I learned of this snake.
The picture was of a large adult --pale body, the namesake striping dark and precisely defined. I thought the snake, although quietly colored, was a thing of beauty. And somehow, through a subsequent lifetime that has involved herps, invertebrates, fish, birds, and mammals, whenever rat snakes were discussed, at some point in the conversation a vision of this species, Elaphe quatuorlineata, has always popped up.
Despite the memories, it was actually about 65 years after seeing the drawing that I first saw this taxon in life -- in 2011, to be exact. After having tried and failed to acquire a pair of this European beauty over the years, I finally succeeded in getting three hatchling males from a German breeder.
As with many of our American rat snakes, the hatchling four-lines were very strongly blotched and gave no indication of the future lineate pattern. Today, the snakes are about three-and-a-half feet long, and the juvenile blotches are much less evident, the stripes are easily visible.
I have been promised a captive-hatched female from the German breeder in the spring of 2014 and am anxiously awaiting its arrival.

The ornate box turtle, Terrapene ornata ornata, is the more easterly and northerly of the two Western box turtle subspecies. It ranges in suitable habitats (and disjunct populations) from northwestern Indiana to southeastern Wyoming and then southward to the Pecos and Rio Grande Rivers of Texas and eastward into southwestern Louisiana.
The easternmost range of the desert box turtle, T. o. luteola, begins at the Pecos River of Texas From there it ranges westward to southeastern Arizona and southward to northern Sonora and Chihuahua, Mexico.
Of the two, the ornate is usually the darker, the more contrastingly marked, and, having nine or fewer radiations on costal scute number two, the less busily patterned.
From the desert box turtle side of the slate, at adulthood this latter usually has a muddier colored carapacial ground color, the light markings are less precise, and the busier pattern consists of ten or more radiations on carapacial scute number two.
Intergradation is well documented in a wide swath on both sides of the Pecos. Males of both subspecies have red irides. The irides of females are white.
Both subspecies of the western box turtle are strongly insectivorous, seemingly with a preference fof orthopterans (grasshoppers and crickets).
Desert box turtles often hunt down their orthopteran prey by walking slowly along the edges of roadways where the grasses are tall and the grasshoppers plentiful. I have watched them sidle along an inch away from and angled 30 to 45 degrees toward the overhanging road-edge grasses. A quick dart of the head and a grasshopper "bit the dust." The turtles seemed quite at home with this strategy and very successful in catching the insects.
I have also observed western box turtles (both subspecies) eating roadkill (lizards, anurans, rodents, lagomorphs, and spiders). It seems that olfactory senses play some part in finding dead items, for on one occasion I watched an insect-hunting female pivot suddenly while in insect-hunting mode and run almost 18 inches onto the pavement to consume a recently killed spadefoot.
Sadly, as seen by occasional box turtles that have themselves been traffic victims at other roadkill, eating roadkill places the turtles at considerable danger from traffic.

![Henry](/blog/uploads/AsianWoodHenryFace.jpg) I don’t remember exactly how large these were when I got them. Seems that a carapace length of 2 or 2-and-a-half inches would be about right. Today, after five years with us, they measure in at about 10-and-a-half inches, and they’re still growing.
"They" are a pair of Asian giant wood turtles, Heosemys grandis. And I decided to get them because of fond memories of Henry.
Henry was the largest (straight measure carapace length of 16-and-a-half inches) and bulkiest Asian giant wood turtle I had ever seen. He was also the most arboreally inclined. And before I realized his arboreal inclinations, he escaped the large outside turtle pen twice.
At first I thought he had merely climbed the fence. Many "wood" turtles of several species are adept at this. I thwarted this possibility by nailing a several inch overhang all along the top of the fencing. But then Henry disappeared again. Some apartment-dwelling neighbors found Henry several days later nestled on the second floor in a corner of the stairwell. Thankfully he was returned. Whether he climbed or was carried was never actually determined. But we think he climbed.
Why do we think that? Simply because several months later, Henry disappeared again. We tried and tried to find him, but failed. Then one day he reappeared in the yard. Hmmmm, I thought, someone had found him and brought him home. A couple of days later Henry disappeared again. And we were just about to discontinue the search when a shaking in the center of a clump of Areca palms in the turtle yard drew my attention. And when I finally looked up, there sat Henry. He had found a half dozen trunks growing closely enough to enable him to wedge his shell between them and inch his way upward. There he sat, looking as if he belonged, about 15 feet above the surface of the mounded palm cluster. And over the years, until one of the palms died and it was no longer possible for him to climb, Henry would periodically return to his tree house.
The giant wood turtles I have now don’t seem to have any arboreal tendencies at all. But neither do we have clumped Areca palms growing in the pen nor are the turtles yet fully adult. Time, I guess, will tell.

The color of the tiny, endangered Harlequin Mantella, Mantella cowani, makes it a perfect candidate for the alternative name of "Halloween Mantella."
Once sporadically imported for the American (and other) pet trade, it has been several years since it was last available. This frog occurs in high altitude forests and seasonally in wet grasslands in eastern central Madagascar.
As is often the case with localized herp species from areas that are difficult to access, very little is know with certainty about the biology and life history of the inch-long Harlequin Mantella. It is apparently diurnal. The clicking vocalizations of this frog have been heard from shallow stream edges and damp rock crevices. The fewer than 50 eggs are laid in protected damp leaf litter and mosses but the life of the tadpoles remains unknown.
Although no longer legally collected for the pet trade, continuing deforestation and other habitat modifications seemingly remain very real threats to the long-term existence of this remarkably beautiful, Liliputian anuran.

I grew up only a few houses away from a fair-sized lake in Massachusetts where I spent a lot of time as a kid watching musk and painted turtles in the shallows and American and Fowler’s toads when they gathered on the sandy shores in the spring to trill or scream, and listening to the plunking notes of green frogs and the jug-o-rums of Bullfrogs, Rana catesbeiana.
Jug-o-rum? I listened to the squeaky fright notes of first-year bullfrogs along the lakeshore and to the deep bass of the old territory-holders out in the lily-pad patches, but I’m not sure I ever heard one of those bullfrogs say jug-o-rum.
I read Conant. I read Behler and King. They both mentioned the jug-o-rum calls. So I began listening to bullfrogs in earnest. I listened to the bullfrogs on Longmeadow Flats. Heard a lot of deep notes, but jug-o-rum? Nope. Ditto for the ones in northern New Jersey, for all in southeastern South Carolina, and for others in north Florida.
"Brrrrrrrrrrummmmmm," or maybe "urrrrrrrrr-ummmmmmm," but no matter where the chorus was heard -- Maine, Texas, or Baja California -- I heard nary a jug-o-rum amongst them. Not a one!
So one hot summer night, seeking validation for my inability to hear what seemed to be the traditional call, I talked Jake Scott into a bullfrog search and listen foray in north central Florida. We found a spot that was literally resounding with bullfrog vocalizations. I listened and, happily, didn’t hear a single jug-o-rum. Ok, Jake, I asked, what do the bullfrogs say? His answer was immediate: "Jug-o-RUMMMMMMM."
I give up. Jug-o-rummmmmm it is.

![The protagonist, a red-shouldered hawk.](/blog/uploads/hawk.jpg) Under ordinary conditions I like birds of prey. But the red-shouldered hawks in this neighborhood have about outstayed their welcome, at least from me. The hawks moved in, built a nest in a big pine a few houses away, and set up serious housekeeping. First it seemed to be the introduced Cuban Brown Anoles that were the preferred prey. Although I enjoy watching the anoles they really don’t belong here and there seems no way the hawks could get them all anyway.
A few years ago, Patti and I decided that the Southern Toads needed a helping hand to make it through what seemed to be a never ending drought. We put a little 10 x 12 foot pond up on the hill and toad song again filled the neighborhood. And Southern Leopard Frogs moved in. The toads were pretty nocturnal but the leopard frogs were active both day and night. The hawks soon found these. New prey.
But then the Eastern Garter Snakes and Southern Black Racers also found the frogs in our puddle. The snakes moved in and their populations persisted for about three years. It was nice to see a big racer periscoping for frogs.

Our screened back deck is a wonderful addition to the house. Rather than a deck we refer to it as our aviary, for it is home to a half a dozen European goldfinches that entertain us non-stop. But we could just as well call it our "lizardarium," for despite deterring the omnipresent mosquitoes many local lizards wander in and out along pathways known only to them.
Broad-headed skinks appear now and again, but most of the lizards are one of two kinds of anoles, the native green or the introduced Cuban brown. The green anoles are the most active and the most arboreal, and as I watch their antics my thoughts often drift back to the first green anoles I ever saw.
It was in the 1940s, I was 7 or 8 years old, and the anoles, a slender golden chain affixed around their neck (no photos), were being offered for sale as living lapel decorations at the New York Sportsman’s Show.
They were being sold as American chameleons, and with them came a care sheet that explained that all the purchaser needed to do to assure the lizard a long life was to provide it with sugar water.
I had never seen such wonderful creature and sugar water would be easy enough to provide, so I wheedled my parents into buying me one lizard. Through trial and error I learned that the little lizard needed a much more varied diet than sugar water and that when he was turned loose on my mother’s houseplants he avidly hunted houseflies and other insect repast.
Could this little lizard have been the cause of my lifelong infatuation with herps? Well, it and the long ago herp supply company, Quivira Specialties, certainly were contributors to my lingering interest.

The car was far ahead of us when it swerved sharply. What, we wondered, was the reason for that?
Jake and I were road cruising and not in any real hurry. The car ahead had disappeared from sight around a curve, and we were now near their position when they had swerved.
Suddenly Jake yelled, "Canebrake!" And sure enough, lying almost dead center in the road was a 4-and-a-half foot long canebrake rattler, Crotalus horridus "atricaudatus."
As I slowed to a stop, Jake grabbed a hook and piled out. As he neared the snake, now alerted, another car approached from around the curve. Jake touched the snake on the tail and fortunately, the snake proved to be a runner. It wanted no familiarity with anything and darted across the road, but then stopped on the grassy verge and looked like it was heading back. We stopped it.
The other car, filled with young women, stopped near us. They asked in unison, "What is it?"
"Rattler," Jake replied.
"What are you doing with it?" one of them asked.
"Keeping it off of the road." I replied.
"Let it go," one of the young women said. "We came back to kill it."
"Looks like you’re out of luck," I told them.
"You’re not killing this one," Jeff said. A couple of more unintelligible comments, and they left.
Gives me a warm, fuzzy, feeling to know that Jake and I were able to save this big male from the road idiots.
The locale was rather open, and once the canebrake was in the canebrake, having slowed to cross the roadside ditch, we guided him to the foot of a big pine.
Once against it, he coiled quietly, a monarch of the southern brakes.

![Note the very prominent](/blog/uploads/Grumpy3.jpg) The last time Patti and I visited the Daytona Captive Breeders Expo was four years ago. I had looked at about all of the ball pythons and leopard geckos I chose to see on that day, and we were taking the long way around to the exit.
As I was passing almost the last sales booth in that aisle, I glanced to the left and stopped in my tracks. In one of the half dozen tanks on the table was a beautiful lizard that I recognized immediately as a Diploglossus lessonae. I sidled over to the table, and as I got there my interest in the lizards was sidetracked by a tank of frogs.
They were a Pacman-type frog but of a species I had not before seen. The vendor asserted that they were Brazilian horned frogs, Ceratophrys aurita. Based on that, I purchased the only one of the three that looked in good condition. This was a male and even he had what appeared to be a corneal lipid deposit on one eye. We named him Grumpy. Philippe deVosjoli bought the other two, and I believe that they are still alive. Philippe determined that the species was not aurita as initially thought, but was another Brazilian taxon, Ceratophrys joazeirensis, a mid-sized species.
Whatever this little frog may be, he has now stared at me morosely for the better part of four years. His periods of quietude are interspersed with an occasional night of vocalizing as thunderstorms or tropical depressions roll through. And he has never once refused his nightcrawlers. Not once.

Stopped by the little turtle pool, as I do each morning, and found a hatchling turtle floating in a patch of sunshine. I took a hurried look around on the surrounding land and found a a hole about an inch in diameter and 3 inches deep.
Inside were four eggshells. There was no question about the identification, The only species housed there had been Rhinoclemmys pulcherrima incisa, the Guatemalan (painted) wood turtle. The adults were now in a large pen for the summer rainy season.
This turtle, if you’re not familiar with it has a brown, rough surfaced, carapace that may be quite flat, rather highly domed, or somewhere between these extremes. The carapace is a warm brown (color is sometimes hard to determine because these turtles are adept and persistent at kicking dirt upon themselves) and the yellow plastron bears a large, dark central blotch that is often weakly edged with pale rose.
But it is the facial neck and forelimb patterns that give rise to the common name of painted. The brown to grayish face and anterior neck bears a complex of thin, but easily visible, bright red stripes. The red striping is also present on the anterior surface of the forelimbs but there the striping is broader and even more pronounced. All in all, these are pretty turtles and at least as importantly, they are hardy and easily cared for.
It seemed apparent that there were no more hatchlings in the pond, so I began a methodical search of the surrounding area. Looking amidst and around the grasses disclosed one additional hatchling. The next day, following a hard rain, I found the third, and on the third day I found the fourth baby. I had now found a hatchling for each of the empty eggshells.
The hatchlings (all brought indoors) are quite like miniatures of the adults in appearance, but have less strongly textured carapaces and rosier plastrons.
I wonder if a second nesting occurred this summer. Another month and I should know.

The little creek puddled out a bit as it neared the road and then was constricted narrowly into a metal culvert that passed beneath the road. Upstream a bit, the creek narrowed and gurgled merrily downhill around and over some boulders. Still further upstream, the boulders were larger and the creek was even more precipitous. Beyond that I couldn’t see from my current vantage point, but I’d soon know the scope of things.
To either side of the creekbed grassy meadows interspersed with small escarpments and many boulders sloped far upward, and at their summits were stands of pines. We started at the bottom and began working our way upward. Tough walking. So we moved to the grassy slopes and slipped and tripped our way to the top (hoping all the while for no encounter with a hidden timber rattler), reaccessed the stream, and began our walk downward. This was a little easier.
We were at this creek in the hopes of finding a seal salamander, Desmognathus montanus, exhibiting piebaldism. Kenny had been told by a researcher that there was a high incidence of this aberrancy at this locale. In fact, his initial information was that all of the seal salamanders in this creek were piebald.
We walked slowly along the creek bed, turning and replacing an occasional likely-looking, water-swept rock along the way. Going was slow, but with the first few salamanders found we determined that definitely not all of the salamanders were piebald. In fact, as the day wore on and one after the other the salamanders proved normal, we began to wonder whether we’d actually find one that was piebald.
We did. In fact we found three, one adult and two juveniles. We extend a big thank you to Kenny’s sources!

The little car bumped and thumped as we raced along a nearly dark forest road in North Carolina. Our destination was one of those many that appeared only a mile or so away on the map, but when you factored in the twists, turns, ups, and downs, bumps and thumps, it proved to be a good 30 minutes from our starting point.
Salamander was the name, and finding them was the game. The little salamanders that we sought were the red-legged and the red-cheeked variants of the Ocoee salamander, Desmognathus ocoee. These are harmless mimics, if you will, of the distasteful Jordan’s salamander complex phases.
We finally sped into a parking area overlooking a deserted campground. And in the middle of the campground was a ring of sizable rocks and a dozen or more well charred log sections all topsy turvy atop a bed of ashes. I spent some time flipping logs and rocks in the surrounding woodlands. Kenny headed straight for the campsite. By the time I got to that area he had already found Red-legged Salamanders, Plethodon shermani, Blue Ridge Two-lined Salamanders, Eurycea wilderae, and several of the desired color variants of the Ocoee Salamander, Desmognathus ocoee.
But for us the best was yet to come. Beneath one log we found an Ocoee Salamander that rather than either/or was gaudily clad in red not only on the cheeks but on the legs as well. This was a variant that neither of us had been aware of.
Success, and now the long drive back to hustle and bustle of the peopled world.

If you take the time to look back into the nomenclatural history of the northern leopard frog, Rana pipiens, you will note at least two names that were long ago hidden in synonomy.
Both were of northern populations, Minnesota and Wisconsin to be specific and I found both to be just different enough from a typical northern leopard frog to be of interest.
One variant, Rana pipiens burnsi by name, was nearly devoid of the oval leopard spots that typify the species.

The little dugout angled out of the river and approached our dock. In it sat a villager holding something at bay with one paddle while deftly maneuvering with another.
Mike Pingleton was closest, and even before the boat touched shore, he was excited. And well he should have been, for unlike one of the more common snakes the villagers usually bring us, on the bottom of the boat was a two foot long creature clad in scales of tan that were arranged in annuli.
The villager lifted the creature gently on a paddle, and Mike soon had it in hand. About the diameter of a thumb, we were all soon staring intently at a fairly common but seldom seen, legless, burrower, a Giant Worm lizard (more correctly a Giant Amphisbaenid), Amphisbaena alba.
Besides lacking limbs, this intriguing creature lacks functional eyes. The scalation is arranged in prominent rings that give it the superficial appearance of a gigantic earthworm.
To many of us, the appearance of this very specialized lizard-like animal was the high point of the trip.

I have struggled with hatching Gray-banded Kingsnake ( Lampropeltis alterna) eggs for the past 34 years. Just when I feel I have it figured out, I have major catastrophes occur such as babies dying full-term in the shell, severely kinked babies, and babies not absorbing their yolk sacs.
I have tried vermiculite, paper towels, sand/peat moss mixes, and peat moss to varying degrees of success. Lately, I have been using peat moss employing the following strategy.
First, I use peat moss soaked in spring water for about fifteen minutes. I then squeeze out as much water as possible and “fluff” up the moss. I place the eggs either on top or in the middle of my peat moss in a half-gallon plastic jar with a tiny hole at the top. Then I place the jar in my incubator set at approximately 78 °F (25 °C).
I find the results to be similar if I have the eggs on top or sandwiched in the middle of the moss. Using this strategy, I hatch out MOST of my fertile L. alterna eggs; I still have some die full term in the shell or with severe kinks; however, most of my babies come out fine.
Feel free to describe your strategies to successful egg incubation!

How could this be? Was I delusional? We were treading a narrow trail through old secondary rainforest in Amazonian Peru, not in southeast Asia, the bailiwick of the green water dragon.
We were out late. It was after midnight. And there, sleeping soundly on a supple limb at face height, was a foot long green lizard that looked an awful lot like the dragon with which I was so familiar. Big angular head, somewhat stocky body and tapering tail. Vertebral crest, sturdy legs.
As I photographed the sleeping lizard I was doing an extensive memory search and finally, as a default, came up with the hoplocercine genus Enyalioides, the forest dragons. And following through on the thought process led me eventually to the Amazon Forest Dragon, E. laticeps.
This was exciting, for I had never seen one in the wild. I could now count this as a lifer on my ever growing life-list.

One by one we have found and photographed over 130 species of herps on Madre Selva Biological Preserve. The Preserve is located on the banks of Peru’s Rio Orosa, a few dozen miles upriver from its confluence with the mighty Rio Amazonas.
But there is one species, a hallmark of Amazonian reptiles, that continues to elude our wandering gazes. This is the Basin form of the Emerald Tree Boa, Corallus batesi.
We are elated when this magnificent snake is found one river up or down Amazon from the preserve and we then renew our efforts to find it. The intensive searches, by day, by night, in fair weather and foul, have probably led to our finding of more than a dozen other elusive species, and for this we are grateful. But it would be so very nice to be able to add an emerald to the ever-burgeoning list.
During January of 2014 (the normally rainy Amazon summer—it’s in the southern hemisphere) we will be trying again. Wish us luck. Or come on down and join us!

When I saw my first living Western two-lined forest pit vipers, Bothriopsis bilineatus smaragdinus, in the wilds of Amazonian Peru, it was more or less because of a fortuitous rest, During that rest, a clutch of four neonates had been found coiled quietly on the broad leaves of a trailside shrub.
Patti and I were leading a herp photography tour, and earlier that day one of the participants had asked me what snake I had yet failed to see was highest on my list of "want to sees." My answer to her had been that it was this arboreal pit viper, a taxon that I had searched for on many other occasions but had failed to find.
In fact, I had seen this black-peppered green subspecies only two times before. The first time had been in the cages of a northeastern reptile dealer. The second time had been an adult that had been killed by a Peruvian villager. Therefore I knew that the snake occurred in the forests that now surrounded us. But time and again Patti and I had walked various trails and failed to see the creature.

All in all a spectacular night. Rained for the entire night. Periods of light rain then periods of driving rain. Driving rains dominated the night until about 22:00, and then light rains prevailed.
So the rains finally came, and within hours areas that during the drought had seemed seriously herp-depleted (and perhaps in what were pre-drought actual numbers they are) were transformed into seething masses of reptiles and amphibians.
It was wonderful to again hear the voices of frogs, toads, and treefrogs, voices long silenced by enduring drought, emanating boisterously from newly replenished waterways and roadside ditches and to see the anuran-eating snakes that are so dependent on the amphibians.
Although the seasonally expected (and hoped for) rains continued in some areas of north Florida, many nearby areas continued to suffer the effects of the long drought. Even where rain fell in reasonable amounts the levels of surface water were lowered quickly by the sponging effects of a substrate too long dry. There remains much catching up to do.
And now that the normal rainy season is behind us and dry weather is again prevailing we are again wondering about the true effects of the long prevailing drought? Has a degree of normalcy actually returned to our seasonal weather patterns or were the two rain events of this year nothing more than lucky quirks?

![The red-ear is readily identified by its red eye stripe. Photo by R.D. Bartlett.](/blog/uploads/RedEar2.jpg) We all know the red-eared slider. For years the quarter-sized hatchlings with the red eye stripe were popular items in pet stores and in the pet section of most department stores. Most were sold as a package deal, a twenty-nine cent baby turtle and a clear plastic turtle bowl with a remarkably kitsch-y plastic palm-decorated center island, both for just $1.50
"Popular" is a bit of an understatement. During the 1960s, U.S. hatcheries produced as many as 15 million red-eared slider hatchlings, all destined for the pet market. Although the vast majority of red-ears never survived the first year (we knew nothing about their food needs, the importance of calcium and phosphorus being unknown at the time), a few did. You can guess what happened to those young turtles that survived long to become wearisome to their youthful owners: plop into the nearest freshwater lake/pond. By and large, this freedom also offered unlimited swimming room, sunlight, few predators, ready access to vegetation, and with luck, interested red-ears of the opposite sex.
Then the US Centers for Disease Control determined that salmonella infections in children might be the result of turtle ownership, and the Food and Drug Administration got involved, ignorning the fact that this bacteria is found everywhere in our world -- outside, in dirt, on plant leaves, on garden tools, on car door handles and inside, on the floor, on counters, on eggs, on fruits and vegetables.
When the FDA created regulations forbidding the interstate sale of baby turtles in 1975, they selected a shell length of four inches as the arbitrary cut-off point. This decision was based, I kid you not, on the idea that a four-inch turtle was too large to fit into a baby's mouth. Never doubt that some governmental decisions are arbitrary.
With Louisiana, the main production state, looking at nowhere to sell their baby turtles but overseas, turtle production dropped to about two million hatchlings a year. Those babies were largely destined for Asia and Europe.
![Young red-eared sliders have distinctively marked plastrons. Photo by R.D. Bartlett.](/blog/uploads/RedEar.jpg) The 70- odd turtle hatcheries in Louisiana went to work and developed methods to hatch salmonella-free hatchling turtles. They did this by washing the newly laid eggs in a bleach solution and then incubating the eggs in temperature- and humidity-controlled incubation chambers. The hatchlings were then placed into clean, salmonella-free bins. These salmonella-free babies were still largely destined for export to Europe, Asia and China, where they were pets, good luck symbols, and raised up and used for human food.
A few young red-ears in Europe, Asia, and China also found their way to freedom in streams, ponds and lakes, and found the living good. They grew up, mated, and generation followed generation. It didn't take long until concerns were raised about competition with native species (sound familiar?), and in 1998 Europe banned the import of non-native turtle species. In Asia, entrepreneurial turtle farmers began raising their own supply of red-ears.
Today, red-ears are found in canals, ponds, and other waterways in Europe and Asia. Jim Harding, a herpetology professor at the University of Michigan, saw them in a pool at the Eiffel Tower (no, they were not wearing tiny berets) and in the Dominican Republic. A professor of sociology at the University of Florida proudly showed me his photographs of a "temple turtle" in China -- it was a red-ear. Red-ears are also found in Japan, Germany, Israel, South Africa, and the Mariana Islands. Their range in the US expanded from the southern environs of the Mississippi River and the Rio Grande River, part of Mississippi, Alabama and far western Florida to Virginia, Georgia, all of Florida, Arizona, California, Oregon and Washington state, and Michigan.
So the next time you see a red-eared slider, admire its ability to adapt. And go ahead -- it still makes a nice pet.

Some days are just better spent sleeping late. Today Jake got me up and running early promising beautiful weather and herps unlimited. He came through on the weather. It was a cool morning then a warmish day that by noontime had turned nearly to hot.But the herp presence—well it was limited at best.
Our herp trip took us about 50 miles northwest of Gainesville, to a spot where both Jake and I had herped many-a-time over the years. We knew that the locale harbored a wide variety of herps -- lizards, a tortoise species, anurans, and snakes. I was kind of hoping for a pine snake sighting but anything, even a garter snake or racer, would keep me happy. Jake dittoed this (but he secretly seemed to be thinking hog-nose). And almost anything would be better than sitting and scanning slides.
Yellow seemed to be the color of the day. The sun was golden yellow, and shone down with an intensity belying the season. Yellow was the color of the flowers, goldenrod, butter and eggs, coreopsis, and others. All out-shone the surrounding woodlands that were adrift with falling leaves, and the remaining leaves were various hues of seasonally tired greens.
But what has all of this got to do with herps? Well, nothing, really, for although we drove slowly for several hours, scouring the roads ahead, to the left and to the right, there was an amazing absence of herps.
We saw some great birds, and were about ready to pack it in when Jake cried, "Snake!"
And sure enough, crossing the road ahead was a black racer ! Oh joy. My day was made! (That’s facetiousness, in case you don’t recognize it as such.)
Well, actually, I do like racers, so this snake was a welcome sighting. Then two adult gopher tortoises were seen feeding on roadside vegetation. Then a long period elapsed with no additional herp sightings until, again, "Snake!" All the while hoping for a pine snake, I looked down and saw the little snake that was lying quietly in the road. I knew Jake would be happy: It was an adult male southern hog-nose.

It was nigh on to one in the morning and I was meandering slowly along a rain-slicked and very muddy trail. The rest of the gang were long asleep on the tour boat.
It had sprinkled most of the day, poured for some of it, and was back to a sprinkle now. Lighting was probably slicing through the distant sky but the canopy obliterated the display. Only the rumbling and grumbling of thunder alerted me to the potential. Something was telling me I was going to get wet—probably very wet (again) very soon. And that something was right on target.
Soon the sound of the thunder was right overhead and rain could be heard in the canopy. It would still be a few minutes before it splashed its way earthward. I began an ascent up a fair incline at about the same time the rain began its descent. Within seconds the incline was slicker than the proverbial greased pig and I was concentrating on every footstep.
Upward, upward---SPLAT! Something big, slimy, and unexpected splatted onto my face. I screamed and as I slipped downward, I knocked it to the ground.
The rain now fell in torrents and I still had no idea what had hit me. But as I moved to the edge of the trail a big brown leaf leapt from the ground and stuck to an upright sapling about three feet above the ground.
I breathed a sigh of relief when I recognized this as a giant broad-headed treefrog, Osteocephalus taurinus.
Enough excitement! Time now to head back to the boat.

What's a coqui, you ask?
Well, if ever you had met a vocalizing male the chances are pretty good you wouldn’t have to ask. From the repetitive, whistled, almost strident, loud and distinctive call notes both common and species names of this diminutive tropical frog have been coined.
Although there are several species of coquis now known (and perhaps more to be described) only one species of coqui, Eleutherodactylus coqui, is known to occasionally visit the United States. Until recently the coqui was thought to have been established in the Florida City, Florida and in the New Orleans, Louisiana areas. It is now realized that the small numbers in each of those populations originally and periodically arrive in potted plants brought from their Puerto Rican homeland.
Here's a little male Eleutherodactylus coqui singing his repetetive and musical "coqui" in the crotch of an orange tree in our South Florida yard.
Coincidentally, I had just brought a dozen heliconia plants from a South Florida nursery a day earlier. Equally coincidental was the fact that the little frog was heard almost nightly until silenced by the first cold snap of winter. Because of temperature fluctuations there seems little chance that this traveler will ever become established in the USA.

For several years now, since our lengthy drought dried their habitats and wildfires swept over their swampland strongholds, I have been unable to find the interesting little carpenter frog, Rana virgatipes, in Florida.
Jake Scott joined me in the search a couple of years ago but despite the return of a heavier rainfall, higher water levels, and a resurgence of the sphagnum in the acidic locales preferred by this pretty little ranid, we continue to fail.
This little ranid was never widespread in Florida. It was restricted to the northeastern portions of the state in the southward drainage from Georgia’s Okefenokee Swamp. Our searches have taken us into some very remote areas, many new for us but all looking like ideal habitat for carpenter frogs. On these searches we have seen many amphibian species -- pig frogs, southern leopard frogs, southern toads, oak toads, eastern spadefoots, and at least a half dozen species of hylids -- as well as many taxa of reptiles. We’ve been in the field by day and by night. We’ve waded the tepid ankle to waist deep waters on moonless nights, on moonlit nights, and during the daylight hours. No carpenters!

No Peeping Tom this, merely a peeping anole. This little brown anole, Anolis s. sagrei, has been utilizing the same shrubs, windowsills and screens outside of my office for about three years now. He lost the distal half of his tail to a larger male a couple of years ago when he was much smaller. It is obviously regenerated and makes him identifiable.
The vertebral crest on this guy is magnificent and the dewlap is often distended and simply held out for seconds on end. He often bobs and displays at me while he is on the horizontal sill and I'm sitting at the computer. He stands his ground against other browns but often darts away from the bigger male green anoles.
He often positions himself on the horizontal frame of the window and from this position he bobs and displays (I feel sure it is at me because he’s looking directly at me the whole time) for minutes on end, and he does this several times a day.

Size differences in populations of the African leopard tortoise are rather well known to hobbyists. Those at the northernmost (top) and southernmost (bottom) extremes of the range attain much larger adult sizes than those in the center.
Perhaps because they are not as well known to hobbyists, the fact that a similar variance in size occurs in the Indian star tortoise, Geochelone elegans, is not as often realized.
My stars, newly received, are of the middle (small-sized) population. They were hatched about 14 years ago by Bern Tryon, Mike Ogle and crew at the Knoxville Zoo, They were kept and coddled for the next 14 years by turtle and tortoise researcher Jim Harding.
Luck alone facilitated their recent transfer to me. Jim decided that he would like the stars to have a bit more “playtime in the sunshine,” so he sent them my way.
Of course, then Mother Nature stepped in; knowing that star tortoises are not awfully fond of excessive moisture, she has provided us with almost continual hard rains. So, with the exception of two or three days, the tortoises' tenure here has been inside with artificial heat and light. But on the few days they were able to go out side each found a sunny patch of grass and weeds, ate until sated, and then sprawled in the sunlight for a lengthy bask.
They seem to be fitting in nicely, and I feel certain that there will be more sunlight someday.

Throughout the decades, ready availability at affordable prices have kept the leopard tortoise, Geochelone ( Stigmochelys) pardalis, high on the list of hobbyist favorites. I have always been on of those hobbyists.
My four leopard tortoises, received from long-time friend and fellow field researcher Randy Limberg, arrived as several day old hatchlings. To say the least their appetite was already on the hearty side and, like Topsy, the little creatures grew and grew -- and grew.
Within a very few years, all exceeded 30 pounds each, and the male was about 45 pounds. They were big, but even more importantly, they were personable, all being completely tame.

![](/blog/uploads/mouseshacksmall2.jpg) Once we have the holes cut and the A/C and vent mounted, it's time to insulate the container. Every side of the container is steel, and every side of the container exposed to the sun will heat up and transmit that heat into the container. The more you can prevent that the better, and barring that, the more you can isolate the inside of the container from its metal sides and top the better.
The best product we have found for both of these are the reflective insulation panels found at most home improvement stores. Measuring 4 x 8 feet, these styrofoam-type panels cost from $10 to $15 each, and have a reflective foil surface on one side with a paper backing on the other. Easily trimmed to shape with an X-ACTO blade or even a sharp pocket knife, it took less than an hour and a can of spray adhesive to insulate the back and side walls, and another hour to seal the gaps between the panels with duct tape.
After turning on the A/C and letting the unit cool down, the next big problem to resolve came when I opened the big steel door. The minute it swung open, all the cool air came rushing out, and in seconds the unit was at the same temperature as the outside air. I had already planned on a fix for this, and within no time I had framed a wall and a pre-hung door 4 feet from the end, thus creating a small storage area and a "cool door" that could be opened without losing the inside temperature.
Finally I tackled the biggest problem, the roof. Initially I wanted to build a steel roof over the container, but in the end I Gorilla-glued 5 of the 3/4 reflective insulation panels to the outside of the roof. Designed for exterior use, they will survive all but the largest hail, and once the glue had dried, be impervious to wind. Best of all, where touching the roof from inside was once similar to grabbing a hot dinner plate, it was now cool to the touch and easily air-conditioned.
Now our mouse shack is ready to go!

Dennie Miller was excited. He had recently learned of the existence of a “new kingsnake” in Texas. This was the Blair’s kingsnake, a species that, according to the lore and to Dennie, was the “queen of them all."
Now, he, and we (Gordy Johnston and I) were piling into Gordy’s well aged (almost geriatric) VW beetle with Texas’ Hanging Judge Roy Bean’s legendary region our ultimate destination. Our quest—well, you can guess.
And as luck would have it, on that first hunt we succeeded in finding not one but two of those coveted kingsnakes that are now known, after several taxonomic modifications, to be a color variant of the gray-banded kingsnake, Lampropeltis alterna.
The first was a dark phase, and it was found beneath the cattle guard almost at the door of Bill and Doris Chamberlin’s old Langtry gas station.
The second one, much more brilliantly colored, was crossing the Comstock Road.
