I have been hiking the Lake George region for the past several years and have not come upon any rattlesnakes, however I did hear there were numerous snakes at Buck Mountain last year. Population declines have also been noted throughout the Timber Rattlesnakes range in the United States, particularly in New York, Pennsylvania, Virginia, Connecticut and New Jersey (Brown, 1981, 1993; Reinert, 1990). They exhibit high fidelity to hibernacula (Odum, 1979; DeGraaf and Rudis, 1983), and some snakes follow specific routes to and from hibernacula each season (Brown et al., 1982).

Dover Publications, Inc., New York. The preferred prey is rodents and other small mammals; however, the snakes also eat carrion, reptiles, amphibians, and birds, and their eggs. They tend to disperse upslope to high ridges removed from human settlement when they emerge from hibernation (Brown, 1981), and move in a looping pattern during the active season that returns them to the same hibernaculum (Reinert and Zappalorti, 1988b).
