These two pictures were shot @ the Dunwoody Hunt Club located north of Montoursville Pa. The Dunwoody club is located in the mtns. and hosts a very large population of Timber rattlers. A natural colony which has been there for years and has been studied by the scientific community and filmed by National Geographic. I was lucky enough to spend time with a long time club member who is also a herpetologist. It was a truly educational experience spending the day walking amongst and learning about them. I am not a real big fan of snakes but left with a lot more knowledge and less fear after this day. Like all critters, they have a place and a purpose in this universe.
They sure are interesting critters. I used to catch snakes all the time as a kid. I even found a baby rattler, but left it alone as I knew that they are more dangerous than adults.
We only have a few venomous snakes in the US I believe. Corals, copperhead, cottonmouth, diamondback, and timber rattlers. Fortunately for me, we only have timbers up this far, and I've never seen one. Cottonmouth don't make it north of southern Indiana / Illinois. Corals are rare and don't attack that much. Copperheads are not the most deadly even if bitten, probably won't die. Cottonmouths are nasty and cause your flesh to rot away. Don't know about timbers, but diamondbacks are bad. With the rattle snake roundups, the silent one's aren't discovered and are breeding that trait, posing a larger threat to humans. Saw a show on it. Don't like any snakes, but I won't harm them either unless necessary.
http://www.backyardnature.net/snakvenm.htm There probably are many versions of rattlers that are all deadly.
Yes...gotta' love that. No way can they survive the long winter. I always in the back of my warped mind thought it would be neat to have several variants of deadly snakes in an open area when it was 20 degrees out. They would be completely paralyzed by cold and couldn't move.
