Timber Rattlesnakes - Crotalus horridus


I started collecting venomous snakes when I was still in Junior High School, hiding the cages in my bedroom closest. I think the attraction was pretty simple. Despite all of the exotic animals around the house, hot snakes terrified everybody else in my family. In high school I met several guys from the Staten Island Zoo who made an annual trek to South Carolina to collect Eastern Diamondback Rattlesnakes, trips chronicled in Carl Kauffeld's book The Keeper & The Kept. I got to tag along. As Director of the Staten Island Zoo Mr. Kauffeld managed to display all of the native forms of Crotalids found in North America. Only Jim Murphy reptile boss at Dallas Zoo in the 1980's managed to put together a similar collection. Studying ethology in Gainesville is was natural that I decided to focus on fieldwork looking at reproduction in Crotalus horridus, The Timber Rattlesnake, found widely in the northeast and pockets of the midwest. Beginning in the 1950s volunteer fire departments in rural Pennsylvania would hold annual "Rattlesnake Roundups" collecting timber rattlesnakes and awarding prizes to hunters who captured the the biggest snakes and the most snakes. Some roundups would collect as many as 400 rattlers in a single day. By 1980 the Pennsylvania Fish Commission became concerned that roundups were endangering threaten C. horridus populations. Several herpetologists were contracted to study the hunts, and as part of the project I began to commute to PA from New York City on weekends in June (when the roundups were held) to assist in measuring and sexing the snakes, and to return the animals to the sites where they were collected by hunters after the competition had ended. I worked at the Bronx Zoo then, so getting back into the field with a stipend from the Fish Commission was a pleasure. Eventually Pennsylvania set strict limits on the number of snakes collected by the round-ups, and specific protections were added for gravid females. The last time I visited a roundup was 1990. I was living in California then after several years in Honduras and my wife Sharee wanted to see what the roundups were about. I'm pretty sure that day in June was the one and only time an Aussie woman with corn-rowed hair entertained the roundup crowd tail-walking large rattlesnakes around the "snake pit" and posing for pictures. But then as she said, she'd kept brown snakes and tiger snakes and taipans in her closet growing up. Today she lives in Cairns, in Queensland reworking the taxonomy of seasnakes. I bring all of this up because although I think rattlesnake roundups were and are somewhat detrimental to rattlesnake conservation, I still believe that animal shows presented by people who actually know what they're talking about remain important. Popular science is not evil, and education can be wonderfully subversive when presented in the guise of entertainment whether the animals are mammals, or avians, or herps. Sometimes I think that zoos have lost their way when they cease to attempt to entertain. Likewise I wonder about the circus menagerie that fails to educate. As an animal guy whether I'm leading a camel, or scraping feces from a cat cage, or playing with a croc, I'd like to think that the people who are watching will leave knowing something about that animal that they didn't know before. Because then maybe they'll care about that animal. Anyway it's almost June again, and in Pennsylvania the timber rattlesnakes are moving away from their winter den sites. The quintessential American viper still reminding those who pass by, "Don't tread on me."

Ben,
I agree entertainment is beneficial. I don't know if I agree with it on the grounds of education. That concept was very important years ago, but I think there are superior media now doing a far better job of that. Shows/entertainment like the popular snake shows, small animal seminars in zoos are great for entertaining and educating a certain age group. Monkeys riding a bike, tigers jumping through hoops, and elephants sitting up are purely that and no more educational or insightful into their potential skills in the wild then Secretariat trotting up and down the paddock fence, gives us the impression of winning the Kentucky Derby.

We call it infotainment and we stiil do pit shows with reptiles at schools, shopping malls and agricultural Shows. Matter of fact, next week I'm off to a 2 day Ag Show about 650 kilometres away with a mixed bag of freshwater turtles, different lizard species, young estuarine croc, carpet python and elapids such as death adder, tiger snake, inland taipan and the stunningly beautiful Collett's snake.

The booking will be entertaining, educational and earn me a few bucks too!

It is infotainment. And while certainly it's not the purpose of a zoo, or a circus, it's a worthwhile effort. (Of course it's the absolute purpose of a touring reptie show, or birds of prey show, or naturalistic animal show.)

Wade I'm not sure that I'm talking so much about a monkey on a bike, or a cat jumping through a hoop. Probably something more along the lines of streaming video of a cat in the wild jumping from boulder to boulder scrambling up a rock face, the recreating that behavior in the arena on pedestals to demonstarte how something perfectly normal can be trained and dressed up as a trick. But more importantly I mean leaning on the shovel for a moment and taking the time to talk to the public and answer questions during the normal course of working. Too many people in zoos and circuses don't. Or on circus they decide to shave ten years off an elephant's age and add ten to its life expectancy rather than saying, "Yes, she's an old elephant." We ought not discount fascination. There's nothing wrong with turning off the grinder and explaining why we work on feet and nails. Or explaining why the cats need a fast day. Or even talking about why a ride pony isn't shod.

Ben,
I don't think the absolute purpose of a traveling snake show is education. I believe as Steve stated making a buck is a major consideration. And I think they get a much better depiction of an animals leaping ability by video, book, or other media outlets. The benefit if done right, is the physical conditioning/keeping in physical/mental shape the actual animal. If as suggested, wrong information or self serving information is offered, of what educational benefit is that?
Why does a cat have a "fast" day? I have been told a dozen different reasons in our field, and I have only come to one conclusion. Speaking to politically correct work usage, in England it was/is referred to as a "starve" day.
We also don't want to misinterpret fascination at times, with nothing better to do/waiting for the next show, and politeness/could care less.

LOL... Wade, absolutely the purpose of the snake show, or raptor show, or whatever is making a buck...maybe even a few bucks. But shows of that ilk are framed around "education," and sold as educational, and if they're done right the audience learns something.

Clearly there are trade-offs. I'm sure you're right, watching a well made wildlife film may be superior to any attempt a show can make at presenting natural behaviors -- but it doesn't provide a visceral experience, something to remember because you've witnessed it. It may very well be that sending a cat bouncing from pedestal to pedestal (as the cat sees it) serves no purpose beyond exercise and a reward on the end of the meat stick. But if the audience for the program remembers a bit of it and if a few of those people later contribute to World Wildlife Fund to help set aside more snow leopard habitat in Nepal around Mustang because they attended your show and saw snow leopards...on a micro level the presentation benefited the zoo or circus or wildlife show, while on a meta level it benefits the efforts of a conservation organization.

Did you ever read any of the debate that raged in the '60's between Heine Hediger the Swiss zoo director and Herbert Ratcliffe of the Penrose Lab at the Philly Zoo on nutrition in big cats? Ratcliffe strongly supported prepared diets like Zupreem arguing that they offered better nutritional balance than whole meat diets. Hediger favored fresh horse meat and felt that in captivity it was particularly important to give cats whole bones to gnaw on as he believed it was naturalistic behavior that relieved boredom and reduced dental problems. What both men decried was the obesity so common in zoo cats then and both felt that fast days were "natural" -- combating obesity and related kidney disease. You could probably state accurately that cats getting sufficient exercise and controlled portion sizes don't need to fast.

What's criminal are the places that chronically underfeed to save a few bucks and still fast the cats -- something I've seen in bad "sanctuaries" etc.
