In January of 2013, Patti and I were in Amazonian Peru with about 15 other herpers. We had spent five days on Project Amazon’s Madre Selva Biological Preserve on the Rio Orosa, and had just moved back upriver to their Santa Cruz Forest Preserve.
Since our last visit, a lazy creek I remember as barely flowing had been dammed and had flowed sufficiently to form a several acre pond in a low-lying clearcut before trickling over the dam to reenter the dense secondary forest. The pond, now two years old, had provided new habitat for spectacled caiman, fish, and in banana trees along the banks, for Bob; for many Bobs, in fact.
Bob, a treefrog, had been named by our gang for his call, “Bob”—not Robert, not Bobby, just plain old Bob, spoken in a guttural croak. Big, angular, with actions and reactions relatively slow, Bob and his brethren sat, usually one to a banana tree, on the leaf stems about waist to head high. Bob was forest green dorsally, grayish to buff ventrally, and laterally had a jagged line of dark rimmed light spots separating the dorsal and ventral colors.
Bob was (and is) a giant monkey frog, Phyllomedusa bicolor. Among the largest of his genus Bob was about 4 ½ inches svl (snout-vent length), had huge parotoid glands and when he moved he as often moved in a deliberate hand over hand fashion as by jumping.
Every night at dusk, Bob (all the Bobs, in fact) emerged from the axil(s) of the banana tree(s) to sit boldly on the stem(s) and call loudly into the night. That this seemingly harsh and unwaveringly repetitious call has been successful in bringing females to the various calling sites was amply displayed by the vast number of tadpoles in all stages of development that swam in the shallows of the pond.
The Bobs it seems, and the Bobettes, have found new homes. Long live them all!

Turtles are endlessly fascinating to scientists. Their biology is unique. They were around with the dinosaurs and survived the forces that led to their extinction. And now it turns out they have more in common with birds and those extinct dinosaurs than with reptiles.
From Science World Report:
It turns out that, surprisingly, turtles are not primitive reptiles as previously thought. Instead, they are related to the group that is made up of birds and crocodilians and also includes extinct dinosaurs. It's likely that the turtles split from this group about 250 million years ago during one of the largest extinction events on the planet.
"Turtles are interesting because they offer an exceptional case to understand the big evolutionary changes that occurred in vertebrate history," said Naoki Irie from the RIKEN Center for Developmental Biology in a news release. "The work not only provides insight into how turtles evolved, but also gives hints as to how the vertebrate developmental programs can be changed to produce major evolutionary novelties."

Unwanted or illegal reptiles and amphibians, including three alligators, were turned over to the Suffolk County SPCA on Long Island in New York State in the state's first-ever illegal animal amnesty.
From LongIsland.com:
The event, which took place at Sweetbriar Nature Center in Smithtown, allowed people to drop off illegal animals, no questions asked. Only reptiles and amphibians were accepted, and no penalties were given to individuals who handed over illegal reptiles, as the primary goal of the event was to prevent people from letting unwanted illegal reptiles or amphibians loose on Long Island.
The event was particularly valuable in that three alligators ended up in the safe hands of the SPCA. The alligators were 3 feet, 3.5 feet, and 4.5 feet long. Keeping an alligator is illegal, and includes a fine of up to $250, but releasing an alligator into the wild is a misdemeanor that can lead to jail time.
Just last week, four alligators were fished out of the Peconic River in Calverton near a boat ramp. The 2- and 3-foot-long alligators were sent to the Long Island Aquarium and Exhibition Center.
At least nine alligators were found on Long Island last fall, including two alligators that were found in a supermarket parking lot in Baldwin, one found on a golf course in Wading River, and another found in the parking lot of an Applebee’s in Shirley.
In a separate story, the New York Post reported the alligators were subsequently adopted by the Rainforest Reptile Show, to appear in educational exhibits.

The news has been full of stories about snakes turning up where they don't belong, probably due to warming temperatures as a somewhat late and feeble spring finally takes hold.
In Mississippi, county employees are freaking out over harmless little brown snakes "invading" the local courthouse basement file room. Read more...
More than 100 gartner snakes have been found in a Canadian hospital. Read more...
Connecticut wildlife agencies have some advice for people who are fearful of snakes. “Snakes are probably some of the most misunderstood animals,” said Laura Saucier, a wildlife technician with the DEEP Wildlife Division. “There is no need to fear or hate these reptiles. If you leave snakes alone, they will leave you alone.” Read more...

Most hobbyists have heard about Okeetee and Miami Corn Snakes, Pantherophis guttatus guttatus, but in Florida there are a few other locales that are home to rather distinctive corn snakes.
Like “Okeetee,” actually an area much greater than just the hunt club from which the name was taken, and Miami (again a larger area), Palm Beach and the Everglades are homes to corn snakes that, although somewhat variable, are often identifiable by appearance to locale.
Let’s take a look at the Everglades phase, a corn snake that is often found right in mangrove habitat at the southernmost tip of the Florida mainland.
Usually only 2 ½ to 3 feet in length, the dorsum bears bright red saddles that are heavily outlined in black and separated by a pretty beige ground color. The sides, predominantly yellow-buff to beige, bear small black spots that may or may not have a red center. The belly is typically “corn snake checkered” but often has a hazy appearance.
Although not uncommon, this is a corn snake phase that is rather seldom seen. But if you’re all the way down in Miami-Dade County looking for the coveted maroon on pearl gray corns there, you might as well continue southward to Monroe County and find yourself a pretty Everglades phase.

Robots modeled on baby sea turtles may reveal secrets about evolution
From the LA Times:
To better understand how the sea turtles' flippers work on land, researchers at Daniel Goldman's CRAB Lab (Complex Rheology and Biomechanics) at Georgia Tech studied the movements of just-hatched sea turtles on the beach of Jekyll Island, a coastal island of Georgia.
The researchers noticed that the sea turtles were able to maintain the same speed on both sandy and firmer terrain, by bending their wrists on sandy ground and keeping their wrists rigid when running on hard ground.
In order to study their movements more closely without bringing baby sea turtles into the lab, one of Goldman's students built FlipperBot, a robot model of a baby sea turtle that has the ability to bend its wooden flipper wrist or keep it rigid.
After putting FlipperBot through a number of tests, the scientists found that Mother Nature, and the baby sea turtles, have got it right. The robot was able to traverse a manufactured poppy seed terrain more quickly when it was allowed to bend its wrist. They also found that the robot, as well as the baby sea turtles, slowed down when they encountered previously disturbed poppy seeds or sand.
So, why does this matter? Well, the research can help engineers design robots that can successfully traverse many types of terrain. It might also help turtle conservationists understand what conditions can slow down baby turtles during that all-important first run, and finally, it may even help answer some evolutionary questions.

Say hello to Froggie Mercury! A newly discovered species of frog in India's biodiversity hot-spot, the Western Ghats, has been named after the late Freddie Mercury: Mercurana myristicapalustris.
From TheHindu.com, an account of the discovery of this and one other new species of frog:
The... genus has been christened ‘Mercurana’ to commemorate Freddie Mercury, late iconic lead singer of the British rock band Queen. Mercury (his pen name) was of Indian Parsi origin and had spent major part of his childhood in India in Panchagni, located in the northern part of the mountain range, where the frog now bearing his name has been discovered.
While the ‘Beddomixalus bijui’ was found in the swamp forests of the Anamalai and high ranges of Tamil Nadu and Kerala, ‘Mercurana myristicapalustris,’ is restricted to highly fragmented and threatened low land ‘Myristica’ swamp forests in the foothills of the Agastyamalai hills in Kollam and Thiruvananthapuram districts.

Gordy Johnston and I began our Massachusetts-to-Florida jaunts in the mid-1950s. Like many other herpers who we knew, our principal interest was in the constricting snakes (the lampropeltine species), but we were also very fond of the big, bellicose somber, green water snakes that were to be found foraging and basking in and along the borrow canal* that paralleled the old Tamiami Trail. Although the green water snakes were the dominant species, Florida water snakes and eastern mud snakes were also commonly encountered.
The term “green” can impart many visions, often erroneous, to those of us familiar with the vivid greens of green snakes and green lizards. However, when the term “green” is applied to Nerodia floridana, there are times when one must actually question the validity of the common name.
Young green water snakes are green: dingy olive green, but green. With growth this color may darken until on some aged examples the ground color is such a dark blackish-green that you must use your imagination to perceive the green at all. Over the years these dark colors are those I had come to associate with this species. Despite the fact that the field guides stated that green water snakes may also be brownish, that was a color I was not yet familiar with.
It was researcher Walt Meshaka who first mentioned the finding of brownish green water snakes in southern Florida to me. And, he continued, he had seen red ones also.
Red? A green water snake clad in scales of red? That thought had never entered my mind. But it was because of that conversation that my search for a red green water snake began and continued until a few years ago when, lo!, on a herping trip to the southern peninsula I found both brownish examples and one red one as well. Success was sweet!
And I can unequivocally state that the finding of the latter has done much to change my perception of the Florida green water snake. Green can be beautiful, especially when it is red.

It's a plain fact that a lot of people don't like snakes, even if those of us here don't understand why not. And for some reason, a lot of snake-haters find their way to the kingsnake.com Facebook page, where they feel a need to inform us that they don't like our animals. So a story like this one is both welcome and a little surprising.
From WFLA.com in Tampa, Florida:
A five foot boa constrictor was found crawling around a Super Shuttle Airport van at Tampa International Airport on Sunday afternoon.
Lt. Natalie Brown with Tampa Fire Rescue volunteered to catch the snake after hearing the call go out over the Airport Police radio. Lt. Brown went to the cell phone lot at TIA and found the snake outside of the shuttle. She captured the snake with a pillow case borrowed from a co-worker's bed.
"I do not like snakes," said Brown, "I am just glad that the snake is safe. It was dangerous, the snake was in the parking lot and could have been run over."
"It is a beautiful snake," said Brown who believes it could be somebody's pet.
Thanks, Lt. Brown, for putting aside your own aversion to snakes and doing the right thing, and not just hacking the snake to death as so often happens in similar circumstances!
And herpers, why not head over to the Tampa Fire Rescue Facebook page and let them know we appreciate her compassion?

Fishermen in Pakistan spotted an animal almost never seen anymore: A leatherback turtle.
From The International Herald Tribune:
On Tuesday, a group of fishermen operating a monofilament gillnet caught a large leatherback turtle at Gwadar near Surbandar village. Since the turtle was stuck inside their net, the fishermen brought the turtle to the beach, after which the World Wildlife Fund – Pakistan (WWF-P) helped them rescue it and release it back into the sea.
According to WWF-P technical adviser on marine fisheries Muhammad Moazzam Khan, leatherback turtles are very rarely found in the coastal areas of Pakistan. They have been spotted four or five times before but they were all dead.
“It is our luck that leatherback turtles exist in our sea as these are signs of the existence of life in natural position,” Khan said.
WWF-P has trained the fishermen, who venture out into the sea, to make sure they don’t harm the wildlife that is not of interest to them, such as turtles and whales. “We are happy that our fishermen now have a sense of the value of marine life.” The young fishermen had no recollection of leatherback turtles, but the older ones remember seeing them.

Dusk had long fallen, bats were erratically flitting low over the water, and a moonless night was already enveloping the little lake in Springfield, Massachusetts, where I had been harassing a population of eastern painted turtles for several hours. I had decided it was time to head home for a late supper. Docking and securing the old wooden rowboat I was using required the use of a flashlight, its batteries so used that the beam hardly showed.
As the boat nudged the dock and I grabbed the tie-rope I glanced down into the shallow water just in time to see a smoothly oval “stone” scuttling across the plant-free bottom. And then the flashlight dieWhat had I seen?
d.
I grabbed my bike and quickly rode the half mile home, hoping as I rode that I had a couple of replacement batteries and that I wouldn’t have to delay my return to the pond for supper. I lucked out. Supper was waiting, a set of new batteries was found, and a few minutes later I was on my way back to the lake.
Almost sooner than it takes to tell this tale I was back on the dock, sweeping the sandy lake bottom with my flashlight beam. Within seconds I had locked onto one of the moving stones. Little and black, I could now see a pointed nose on one end and a stubby tail on the other.
Between these were the little black legs that propelled the creature in bursts of speed between which it foraged agilely and avidly on the bottom. A soggy piece of bread discarded by a fisherman, a broken half of worm, a portion of a dead shiner—as I watched, all proved grist for the mill of this little turtle—a common musk turtle, Sternotherus odoratus, aka the Stinkpot.
I was soon soaked to the skin but before returning home that night I had seen and inspected more than half dozen. It was an educational introduction to a species I had never even imagined dwelt in our area.

ExxonMobil is reporting that more than 200 animals, including 125 snakes, were found dead at the site of the Mayflower oil spill, died while being transported, or were euthanized at the clean-up facility.
From THV11.com:
David Eglinton, with ExxonMobil, said 238 animals were captured and 62 were declared dead on arrival, which means they were either found dead or died in transport. Of the 238 captured, 14 died and 64 were released, bringing the death total to 76. One duck, three turtles, and 125 snakes were euthanized, bringing the final total to 205 wildlife deaths.
Exxon said the Unified Command and Arkansas Game and Fish Commission provided for the euthanasia in circumstances where the animals were critically injured or posed a risk to the safety of clean-up personnel.

There's a new lizard species in town, and you might already have one.
From the Somaliland Sun:
Czech amateur herpetologist Tomas Mazur has discovered a new agama species, Xenagama wilmsi, a small lizard with flat "beaver-like" tail, in Somalia, and found out that this is actually the species most reptile fans keep in their vivariums without knowing it, Mazuch has told CTK.
The species inhabits the Horn of Africa countries, Etiopia and Somalia. Its tail is flat at the beginning and it narrows towards its end.
Mazuch cooperated on uncovering and examining the new agama with Philipp Wagner, a professional expert from a Bonn museum.

What do you do if you find an iguana bleeding and wounded by the side of the road? You move heaven and earth to save him, of course.
"Big Guy," an endangered Rock Iguana, was discovered on Brac Cayman with severe injuries, lying on the roadside. Thanks to the generosity of Cayman Airways, he was flown free to Grand Cayman for veterinary care then back to his rehab home in Cayman Brac with volunteer Bonnie Scott Edwards of the Cayman Species Management Team.
You can view extensive photos here, and see more details of his story here.
Oh, and there's a happy ending: Big Guy recovered well and was released to the wild today.

Biologist Tyrone Hayes and his team at UC Berkeley have linked to exposure to the pesticide atrazine to cancer, hormonal disruption, and reproductive failure in frogs and rodents.
From The Eastern Progress:
During [a] trip to Africa, Hayes noticed that one species of frogs characterized by a distinct difference in color between male and female was actually changing to where some of the male frogs were taking on the spotted yellow colors of their female counterparts instead of the male green color.
Hayes had a theory the male frogs were changing because of the contaminates in the water. He theorized that water contained high concentrations of the female hormone estrogen.
When he got back to the states, he tested his theory by giving frogs different types of estrogen, which proved different forms of the hormones were causing the physical changes in the frogs.
After word got out that Hayes’s frogs could tell if substances had a harmful amount of concentration of estrogen, Hayes was hired by Syngenta Corporation to test their herbicide Atrazine.
“Here’s what I found: Atrazine inhibited the growth of the voice box in males,” Hayes said. “Now that’s bad news for the company because the same reason why males have lower voices, testosterone, is the some things that males frogs have that females don’t. This data implied that Atrazine demasculinized the male frogs. I like to use the term ‘chemically castrating’ because it pisses them off.”
He knew that Atrazine was harmful to amphibians, and he knew that amphibian hormones were sometimes almost identical to mammals, so what were Atrazine’s effects on mammals, including humans?
After even more tests and experiments he and his undergraduates at the University of California-Berkely stumbled across a startling discovery. Mammals- lab rodents- that were exposed to Atrazine induced breast and prostate cancer and were also more likely to have abortions.
If Atrazine had these deadly affects on lab rats, what were the effects on humans who were drinking water that was contaminated with Atrazine? What about the farmers and fieldworkers that were constantly being exposed to concentrations of Atrazine over long periods of time?

Frogs, whose voices were once a prominent part of wildlife sounds in the Carribbean, are barely making a peep this spring. And that silence carries deadly implications for both amphibian survival and human health.
From 9News.com:
Without new conservation measures, there could be a massive die-off of Caribbean frogs within 15 years, warned Adrell Nunez, an amphibian expert with the Santo Domingo Zoo in the Dominican Republic. "There are species that we literally know nothing about" that could be lost, he said.
Researchers such as Lopez and his wife, Ana Longo Berrios, have been fanning out across the Caribbean and returning with new and troubling evidence of the decline. In some places, especially in Haiti, where severe deforestation is added to the mix of problems, extinctions are possible.
It is part of a grim picture overall. The International Union for the Conservation of Nature has found that 32 percent of the world's amphibian species are threatened or extinct, including more than 200 alone in both Mexico and Colombia.
"Everywhere we are seeing declines and it's severe," said Jan Zegarra, a biologist based in Puerto Rico for the U.S. Fish and Wildlife Service.
Frogs may be less charismatic than some other troubled species, but their role in the environment is important. They are consumed by birds and snakes and they in turn are major predators of mosquitoes. Their absence could lead to a rise in malaria and dengue, not to mention discomfort.
There's more -- a lot more -- here.
