Friday Roundup: Child-snatching Eagle Hoax and Targeting Turtles in the Road

Conserving Georgia's state reptile, the Gopher Tortoise, requires cooperation between state and federal biologists and private landowners.

An excellent summary of some recent research suggesting that the largemouth bass that are best at protecting their nests and young are the ones most likely to be hooked by fishers. This means that their offspring are less likely to survive. Assuming that the parenting behavior is influenced by genetics, each generation of largemouth bass will be poorer parents-and that means less bass will survive to adulthood.

A Seven Foot, 87 Pound Cottonmouth from Baldwin, Florida

You can follow me on Twitter.

In recent days, several people have brought my attention to a story circulating about a large Cottonmouth, Agkistrodon piscivorus, that was killed in Baldwin, Florida. Fair enough-this is easy enough to believe. After all, Cottonmouths are very unpopular among the general public, perhaps in part due to the numerous myths surrounding the swamp creature. They are also very common throughout Florida.

However, this story quickly veers into the nonsensical because of a combination of two all-too-common themes: 1) a photograph using a camera trick called forced perspective to make an object look larger than it really is (something that happens all the time with Rattlesnakes) and 2) journalists/reporters that are just a little too quick to believe something that might make for a sensational story.

The individual that originally sent me the news article said it might be the, "worst snake story (he) had ever seen." I'm inclined to agree. The reporters don't say how they obtained the measurements on this animal (probably because it wasn't with a tape measure or scale).

Despite what is reported in the story, this snake is not seven feet long (1.9 m) and 87 pounds (39.5 kg). For reference, the largest known Cottonmouth (i.e., the World Record) was only a little over six feet long. Based on my experience with big bulky vipers like rattlesnakes and including Cottonmouths, my guess is that this World Record snake would almost certainly weigh less than ten pounds and definitely less than twenty. So, the length/weight ratios of snakes rule out a seven foot and 87 pound animal. It's not possible. So, even if we accept that the snake is seven feet long (remember, this would make it the longest Cottonmouth ever known), then the weight can't be true. And if we know the weight isn't true, then why should we believe this is the world's longest Cottonmouth in the first place?!

Now, the snake in the picture is a large individual but it looks bigger than it really is. I am hoping someone in the construction or farming business can inform me regarding how far apart the teeth on that 'dozer are (I'm not actually sure that is even a bulldozer).

This picture reminds of a python that was doing the rounds a few years ago. That snake was also hoisted up by construction equipment and claimed to be the world's largest boa. It wasn't.

Updated 12/20/12 9:30 PM

I've now heard from a couple readers (in the comments and via e-mail) knowledgeable about the construction equipment in the picture above. It is apparently a root rake mounted on a tractor and they estimate the teeth are between 8-12 inches apart. So, now we can estimate the snake's length; let's assume the largest possible distance and say the teeth are 12 inches apart. The Cottonmouth clearly spans the gap between two teeth, so that's 24 inches. There is a little slack so we'll round up to 26 inches. Let's be generous and say the head would have reached the next tooth if it wasn't draping down. Now we're up to 38 inches. It's also clear the the back portion of the snake could at least reach the next tooth (50 inches). Let's get crazy and say it could have reached the tooth after that (62 inches). Finally, we can add six inches for the total length of all the actual teeth (not the distance between them). Our final (very generous) estimate is 68 inches, in other words: roughly five and a half feet long-a huge Cottonmouth but no world record.

Saturday Roundup: Bird-eating Catfish and a License to Kill Crocodiles

New research documents giant catfish beaching themselves to grab and eat pigeons (awesome video of attacks above). I don't really get why people are calling them "freshwater killer whales", they seem more like freshwater catfish. Maybe killer whales are saltwater catfish.

Wildlife research doesn't have to happen in the wild. Here's a turtle study occurring in the Bronx River, New York City.

Last week I wrote about a Nile Crocodile on the loose outside Miami, Florida. The Florida Fish and Wildlife Conservation Commission decided they didn't want to take any chances. To avoid any possibility of the Burmese Python problem repeating itself, they now have orders to shoot to kill.

Ever seen a bird nest this big?

National Geographic Photo Contest 2012. Amazing photos, such as the baitfish taking refuge near a sea turtle as sailfish circle; and lessons learned, like don't throw rocks at leopards. Part II: highlight: using fire to catch fish.

A couple weeks ago I wrote about how a shark taking part in a research project off the coast of Africa was killed by people. Now the same thing is happening to research wolves around Yellowstone National Park.

Think rhinos are big today? Compare them to their relatively recent ancestors, from the blog of a researcher who stores lots of dead things in his freezer.

Last year I wrote about some research I conducted in Costa Rica on two very similar snakes. I was curious to know how these snakes could persist in the same area without competing for resources. Looks like the situation is even more complicated in Central and South America than anyone thought, here's a recently discovered species within the same genus.

Friday Roundup: Wildlife News From this Week

Maybe I should re-title these posts as Saturday roundups. 

Twenty-tons of rat poison to help finally rid the Galapagos Islands of invasive creatures. Native hawks and iguanas temporarily relocated. What could go wrong?

Cuttlefish vs. Octopus. Two masters of camouflage in a death-feast.

Speaking of killing octopi. A couple weeks ago I wrote about how the killing of a Pacific Giant Octopus sparked outrage among the diving community. Looks like they're trying to make sure it doesn't happen again.

White humpback whale spotted. Not quite Moby Dick, but still. Incredible video.

We're going to need a bigger boat. Keep track of White Sharks.

Porpoises back in San Francisco Bay after 65 years.

Rare Right Whales cruising South Carolina coast.

Ya can't cage a wild thing. They get bored. Zoos may not be much better. A quote that resonated, "Rather than raising awareness, zoos might be hindering us from recognising the reality. We humans are not the Ark; we are the flood"

Goldfish invasion in Colorado. When I was young, I once released a pet goldfish into a nearby lake. I thought I was doing it a favor. A bass ate it in three seconds. These goldfish have been luckier, until now.

Is this the world's rarest snake? 18-100 St. Lucia Racers remain.

Can we identify snakes by the skins they leave behind?

Too ugly to conserve? You would think people wouldn't eat them.

Drones used to protect wildlife. They don't drop bombs on poachers, yet.

So much left to learn. Surprise! That sea snake is actually two different species.

On that note, here's a new species of lion. In a zoo.

In honor of Thanksgiving. It's easy to forget that the turkey is a wild animal. Don't, their natural history is fascinating.

Wolves are reclaiming Germany.

Grasslands are important and unique habitats for wildlife. An attempt to reclaim them in Australia.

Grizzly bears don't just live in the cold mountains. There are still a few that live in the desert.

But, that said, some are roaming into Polar Bear habitat. And this means we will be seeing more Grolar Bears.

Some animals are hard to find. How can you figure out if a particular species is in a particular area? Catch some leeches and analyze the DNA in the blood they've been feeding on.

I'm still not sure what Tumbler is. But here are some field notes on biology and culture, exploring disease, ecology, and wildlife.

Incredible photographs of owls in flight.

It's too late for Lonesome George. But maybe not too late for his species after all. Could it be that sailors that meant to eat giant tortoises hundreds of years ago have inadvertently saved a species?

The best camera trap photos of 2012. These wildlife photographs are amazing, you have to check them out. Here are the winners and here are the editors' choices. Which is your favorite?

At least one Nile Crocodile is cruising through Florida.

Remember the Spotted Owl? It just received some more habitat.

The Museum of Natural History in New York was a frequent destination when I was growing up. One of the signature displays was and is a life-sized replica of a Blue Whale. Here is the surprising story of how it came to be. In two parts.

One of the rarest fish in the world is not doing well. A very similar species is thriving. What do we lose if we mix them up? Conservation, ecology, taxonomy and philosophy collide.

Bonus points for anyone that can tell me what is wrong with this article about obtaining a sanctuary for Blanding's Turtles.

The Alligator Snapping Turtle: Natural History, Mythology, and Conservation

The following article is a guest post by Brian Folt. Brian is a Ph.D. student at Auburn University, where he studies the community ecology of amphibians and reptiles. He grew up in the Midwest and received a B.S. from Ohio University in 2011. Brian conducts field research in the southeastern United States and Central America. Brian is an avid outdoorsman and a die-hard Cleveland sports fan. You can follow him on Twitter @brianf0lt.

     Here in the United States, few are aware that we actually live alongside one of the most species-rich turtle faunas in the world. Of 320 species known worldwide, 42 inhabit the southeast US, with a hot-spot of at least 18 known from the Mobile River Delta in Alabama. Only the Ganges River drainage in eastern India has a similarly-sized area with more turtle species (but just barely!).

     Turtles of the southeast vary drastically in ecology, natural
 history, and morphology. These animals inhabit a diverse spectrum of habitats, from well-drained pine forests, like the Gopher Tortoise, to high elevation bogs, like the tiny Bog Turtle. Of this diverse turtle fauna, perhaps the most remarkable species is the Alligator Snapping Turtle (Macrochelys temminckii). The largest freshwater turtle in North America, this species is also highly aquatic. Unlike classic riverine turtles which conspicuously bask on logs or shoreline, Alligator Snappers never leave the water to bask or move overland, except when females lay eggs (an annual occurrence) and juveniles move from these nests to the water.

      Alligator Snapping turtles are thought to be sit-and-wait predators: they hang out patiently on the river bottom with mouths agape, waiting for food to come to them. They possess a fleshy structure on the tongue, the lingual lure, which attracts fish or other prey to the jaws. When inquisitive prey touch the sensitive lure, the powerful jaws immediately snap shut, and the turtle receives a nice snack. Bon appétit!

      I spent last summer in the bayous of south Alabama trapping turtles with Jim Godwin, a biologist with the Alabama Natural Heritage Program at Auburn University. Jim is conducting a long-term study of the federally-endangered Alabama Red-bellied Turtle (Pseudemys alabamensis). During this work, however, we also became intimately familiar with Alligator Snappers, as we caught over 40 of these fascinating turtles.

     Throughout the summer, we had the pleasure to talk about our work with many local swimmers, kayakers, canoeists, fisherman, etc. Curious folks generally ask a series of questions regarding the Alligator Snapping Turtles, questions mired in mythology. Here are a few typical questions and the answers I often provide:

How big do they get? 

     Big! Really big. The largest records indicate that some 
male Alligator Snapping Turtle shells can reach 30 inches [0.76 m] long and some whoppers can weigh more than 260 pounds [118 kg]! That’s heavier than Cam, or four scooters. The largest individuals we’ve captured weighed approximately 150 pounds [68 kg]. Because males have different tail proportions and get much larger than females (females generally don’t get much bigger than 77 pounds [35 kg]), this species has what is called sexual dimorphism.

How long do the loggerheads live? 

      “Loggerhead” is a common name that many locals call the Alligator Snapping Turtle. This of course creates confusion because of the large, endangered sea turtle with the same name. Confusion aside, people always wonder how long Alligator Snappers live, and the answer is a long time. Some individuals have lived 70 years in captivity, but we really don’t know how long they live in the wild. Studies have counted rings on shell scutes (“annuli”) to estimate turtle age, not much unlike similar studies of trees or fish. The scute measurements indicate that individuals easily reach ages into the 40s, but estimates beyond this point are unreliable. More long-term mark-recapture studies are needed to determine how long this animal can live in the wild.

Are you going to eat them? 

     No! That’s illegal (and gross). All turtles are protected 
from collection in Alabama, and for good reason. Commercial harvest of Alligator Snapping Turtles in the 1960s and ‘70s by soup companies appears to have severely depleted populations throughout the species’ range. More recently, trappers have been exporting other local turtles to China, where they are highly valued for food and medicine. Because turtles are an important component of balanced freshwater ecosystems, we are attempting to protect and conserve them in Alabama.

But, what are the chances that I’ll be bitten while out for a swim? I’ve heard they can take your foot off! 

     While this may come as a surprise to many, the answer is none! As far as we know, there is no documented case of a hidden Alligator Snapping Turtle biting a swimming or bathing human that is minding their own business. Like most wild animals that encounter people, it seems that the first reaction of Alligator Snapping Turtles is to flee. For these reasons, I’m highly skeptical that an innocent swimmer will ever be bitten.

     Of course, if you pull one of these beasts out of the water, it’s a different story. Like all wild animals, these turtles will defend themselves when cornered and those jaws are no joke. Dr. Peter Pritchard’s classic monograph, The Alligator Snapping Turtle: Biology and Conservation, provides a photograph of a Florida citizen who lost the tips of his middle and ring fingers to a bite from a captive animal. If you are afraid of being bitten by an Alligator Snapper, don’t play around with them! The same concept applies to venomous snakes.

     Through our research efforts, we have learned much about the distribution and abundance of Alligator Snappers in Alabama, and answered a few interesting questions about the effects of historic commercial harvest on this species. In general, it seems that Alligator Snapping Turtles are currently rare in Alabama, but there are a few places where the species remains locally abundant. Unfortunately, despite legal protection in Alabama and throughout its range, this species is occasionally killed by abandoned fishing lines, such as limb-lines or trotlines. This has been a major cause of turtle mortality in Georgia and may inhibit the recovery of populations in Alabama. I urge fisherman, officials, and civilians to more closely monitor and regulate these fishing lines to reduce the by-catch and mortality of the Alligator Snapping Turtle, a truly magnificent component of our native wildlife.

Rattlesnakes In My Yard: Is Relocation a Death Sentence?

           For many people, finding a rattlesnake in the yard does not present much of a dilemma. They just kill it. But, for those people that appreciate rattlesnakes and don’t want to kill them all, encountering one of these venomous animals near the house raises an important question: What now?

            A rattlesnake around the house is a risk that most people just don’t want to take. And, that’s understandable. Inevitably, the topic of relocation is raised as a humane alternative to killing the animal, which is likely just traveling through or was attracted to an abundance of rodents. But, a letter from a reader summarizes a common concern.

A Timber Rattlesnake Relocated by Gary L.
I live in northeast Alabama outside of Scottsboro at the base of a small mountain ridge.  A rocky ravine runs down the mountain right to my backyard.  When I walk out of my back door I am automatically herping (i.e. finding a lot of amphibians and reptiles).  Occasionally a timber rattler will show up.  Since I have several small dogs and don’t want the snakes so close to the house, I relocate them.  I have a good set of tongs and snake bag and can relatively safely handle the snakes.  Initially I took the snakes to a secluded area about 5 miles away.  My conscience started to bother me because I knew that the snakes would not be able to return to their proven den site.  Since then I have taken several snakes a short distance backup to the top of the mountain ridge and, I’m sure, in range of their den.  Now I’m concerned about the snakes being able to find their way back to my backyard.  My question is: ‘Is it a death sentence for the snake if I move it far enough away from its range that it cannot get back to its den?’   


Gary L.

            As Gary notes, rattlesnakes do not just spend their lives randomly crawling across the landscape.  Timber Rattlesnakes (Crotalus horridus) often use den sites throughout their lives. The use of these dens isn’t just a matter of convenience; the rocky and underground caverns are necessary for the snakes to survive the winter in colder climates. These areas provide protection from the cold and from predators. In the fall, females will give birth around their dens and the young benefit from the security of the rocks and also from having a lot of adult rattlesnakes around.

            Timber Rattlesnakes do sometimes disperse from their “home” den and reach other dens to mingle with new snakes, but the point is that there are often unique features of the landscape that are necessary for a snake to survive and these features are well-known by individual snakes that spend their lives in the same general area.

            So, as you might expect, relocating a rattlesnake away from your house isn’t automatically a humane option at all, it may just be dooming that snake to die a slow death in the woods as it crawls around looking for something familiar.

            One short-term option is to relocate snakes only a short distance from your house, perhaps less than 1000 feet (roughly 300 m). This technique moves the snake away from your home but allows the animal to stay within the forest it knows and close enough to its den that it can easily return. As Gary noted, this means that the snake very well could wander back to the house (even if this is unlikely).

            However, most people that go through the trouble of catching and relocating a rattlesnake want a more permanent solution and are interested in moving a snake far enough that it won’t try to return. I’ve written extensively about how living with rattlesnakes is an inseparable part of living in rattlesnake country and the most ecologically-minded (and safest) plan of action when co-existing with rattlesnakes is to take appropriate precautions (like teaching children and dogs about potentially dangerous animals).  Similarly, I never advocate capturing a venomous snake because it is a dangerous activity and runs a high risk of snakebite. I’m going to assume that you know all this but, for whatever reason, you have decided it is still important to move a rattlesnake away from the house.

            To give a relocated snake the best chance of surviving, it should be moved to an area that already has a population of the same species. This is a sure-fire way of knowing that the area is appropriate and the relocated animal can fulfill all of their needs there, which include the ability to find prey, refuge, and mates. If you don’t know for sure that an area has a rattlesnake population, look for habitats that are similar to the area around your home. For Timber Rattlesnakes on the east coast, good habitats would include deciduous forests, ideally with some rocky slopes and mountains. The same is true for another venomous species that shares this habitat, the Copperhead (Agkistrodon contortrix).

            Even when a rattlesnake is moved to a perfect habitat with a resident rattlesnake population, it will still go through an adjustment period. A study conducted in the early 1990’s radio-tracked a number of Timber Rattlesnakes in Pennsylvania to compare behavioral differences between snakes that had always lived in a particular area versus snakes that had been relocated to that area (the relocated snakes had been captured from areas 5-107 miles [8-172 km] away from their new home). I’ll let the original authors (citation at the bottom of this post) describe the take-home message of the study:

Our results clearly indicate that long-distance geographic translocation (i.e., relocation) results in decreased survival and an alteration of the behavior of C. horridus. Specifically, translocated snakes made frequent and extensive movements. The pattern of movements suggested either the snakes were searching for familiar environmental features, or they were exploring the new territory in order to become familiar with the existing conditions. Translocated snakes suffered from higher rates of overwintering mortality, predation, and disease than did residents. Only four snakes out of 11 (36.7%) are known to have survived through two complete active seasons following translocation.”

            This isn’t meant to be all doom and gloom. The authors note that their relocated snakes were able to find denning sites, even if they did die over the winter in higher proportions than resident snakes. In addition, relocated snakes that did survive the first year or so or life in their new home gradually started to exhibit behavior more similar to resident animals. This means that they started to move around less, and shorter movements reduce a rattlesnake’s risk of being found and eaten by a predator (or run over by a car). The authors further note that young snakes may have an easier time adjusting to a new area than the adult snakes that they had moved around.

            A smaller-scale study conducted in South Carolina had slightly more encouraging news. Of four Timber Rattlesnakes relocated from their capture location, none tried to return to their original home and only one had died after a couple of years, when the study concluded. The animals in South Carolina may have fared relatively well because in the southeastern United States, Timber Rattlesnakes do not seem to rely as much on specific denning sites that are used year after year. This may mean southern snakes are more adaptable to changing conditions but more research with more snakes is needed before this can be said with confidence.

            On a very large scale, when confronted with news that an entire Timber Rattlesnake den was going to be destroyed by some highway development in Kansas, a dedicated group of researchers undertook an intensive effort to identify a new suitable home for the snakes that lived there. These researchers looked for new potential sites with limestone caverns (for winter refuge and denning sites) surrounded by large areas of grasslands and fields (Timber Rattlesnakes out west tend to use different habitats than on the east coast) and lots of small mammals to eat. They even made sure that there were appropriate basking areas that faced the sun in the right direction. Finally, and perhaps most importantly, the new habitat would have to be away from too many humans. They found one site that met all of their criteria and moved 29 rattlesnakes from the doomed highway den to this new site. After a couple years of monitoring, it looks like their homework paid off and the relocated rattlesnakes are generally making themselves at home.

            So, is relocating a rattlesnake away from its original habitat a death sentence? Not necessarily. By carefully choosing an appropriate and suitable relocation site, you can give a rattlesnake a reasonable chance of surviving in a new home. Even in seemingly excellent habitats though, relocated rattlesnakes often have a difficult time adjusting and experience a relatively high risk of dying from disease, predators, or exposure.


            This post is focused primarily on Timber Rattlesnakes and the habitats they use, but the same general concepts are true for all snakes. If you want to move a snake away from your home and give it a good chance of surviving, you must give a lot of thought to that snake’s needs and ensure that the new home meets these needs. If you have a snake you want to relocate and you're not sure what to do, you can ask me.

Friday Roundup: Extinct, Almost Extinct, and Not Quite Extinct Anymore Edition

Grand Cayman Island Blue Iguanas Are Now Endangered...And That's Good News: A huge, bulky, and blue iguana that reaches up to five feet long can be found the Grand Cayman Islands but, for a while there it looked like it was on its way out. Because of hunting by humans, interactions with species introduced by people, roadkill, and habitat destruction, the Blue Iguana (Cyclura lewisi) almost vanished forever and was reduced to less than 25 individual animals in the wild. However, because of the work of a few conservation organizations and passionate individuals, a intensive program was initiated to protect the iguana in the wild and bolster their populations with a captive breeding program. As a result of their successful efforts, the International Union for the Conservation of Nature recently upgraded the species' status from Critically Endangered to Endangered. The Blue Iguanas are not out of the clear yet, but this is encouraging news. For more information regarding Blue Iguana and the organizations working to conserve them, check out the International Reptile Conservation Foundation and the Blue Iguana Recovery Program.

New Lizard Species Discovered! Check It Out Fast Because It's Going Extinct: This world has much more to be discovered and described. Just this year, a new species of skink, the Coastal Plains Skink (Ctenotus ora) was found south of Perth, Australia. This lizard's habitat is under siege by an incoming housing development. The animal was almost extinct before we knew it even existed. Now, the question is whether we will allow it to go extinct anyway.

A New Ferret Colony in South Dakota? The Black-footed Ferret (Mustela nigripes) was thought to be extinct in 1979 but a group of the animals was then discovered in 1981, in Wyoming. These animals became the basis for an intensive conservation. By 1987, this Wyoming population had gone extinct too, but there were now some ferrets in a captive breeding program. In 1991, biologists had started to reintroduce the species to the wild and so began a relatively successful conservation story (here's a great timeline). There was some recent excitement about three ferrets found on Standing Rock Sioux Reservation in South Dakota; you see, this was not a site where the animals had been reintroduced and there was some speculation that this was a wild and previously undiscovered population. However, I spoke with Virginia's foremost authority on the species, David Jachowski, and he informed me that federal officials suspect that these three animals have simply wandered away from the nearest reintroduction site, about 70 miles (113 km) south. Not as exciting as discovering a new population, but encouraging news that the Black-footed Ferret may be able to disperse across the landscape and be able to survive in areas in addition to the intensively managed reintroduction sites.
