Conversely, in a study in Georgia, gravid females constituted the majority of roadkilled snakes (Neill, 1948). Striped mutations and amelanistic partial albinos have also been recorded (Hudson and Carl, 1985; Dundee, 1994a). Additionally, some snake hunters claim that Timber Rattlesnakes will not leave the den until they have shed (Ibid.). Martin, W.H. La Socit Zoologique de Qubec. In Pennsylvania, newborns ranged from 220280 mm snoutvent length (SVL) (Galligan and Dunson, 1979). Niagara Falls, NY (14301) Today. Typical litter size varies from five to thirteen young, according to geographic location (Edgren, 1948; Anderson, 1965; Galligan and Dunson, 1979; Brown, 1993) and gestation period can vary as much as four to six weeks, depending on weather (Martin, 1996). Logier, Frank Ross, Craig Campbell and James Kamstra), but no Timber Rattlesnakes have been found (Ibid.). Funding for this effort was provided by the 2010 US Environmental Protection Agency's Great Lakes Restoration Initiative. Because of their late maturing and infrequent reproduction, this life history strategy makes them incredibly susceptible to human persecution and habitat destruction. Cook, F.R. Kim has also written COSEWIC status reports on the queen snake (Regina septemvittata) and the northern ribbon snake (Thamnophis sauritus septentrionalis). In general, they do not strike unless provoked, preferring instead to remain concealed (Ditmars, 1907). Protected public lands and privately owned nature preserves have contributed significantly to the conservation of Timber Rattlesnakes where they still exist (Ibid. Over the years it has become a thriving ecosystem home to birds, fish, turtles, snakes and more! 9. But, for the real treat, skip the bridge and head on. Jensen, J.B., B.W. Harwig, S.H. Myers, C.W. 1991. One seemingly harmless, yet potentially significant example of habitat alteration is the repositioning of basking and shelter rocks by people looking for Timber Rattlesnakes (Brown, 1993). Timber Rattlesnakes (Crotalus horridus) of the Pine Barrens: their movement patterns and habitat preference. Timber Rattlesnakes may be active by day or night; nocturnal activity is especially common during hot summer nights (Martof et al., 1980). The designation of status for the Timber Rattlesnake is quite straightforward: it has not been reported in this country in almost 60 years. Another possibility was that it merely swam or drifted across Lake Erie from a neighbouring population on one of the U.S. islands or mainland (F. Cook, pers. 3h 14m. The Canadian Wildlife Service, Environment Canada, provides full administrative and financial support to the COSEWIC Secretariat. Observations on gravid females in captivity also indicated that the snakes did not feed during gestation (Odum, 1979). The introduction of pigs into the countryside contributed to the demise of the Timber Rattlesnake; pigs are protected from envenomation by their thick layer of fat that prevents the venom from entering circulation, and thus are able to kill and eat rattlesnakes (Nash, 1908). I've heard that there have been reports of people seeing or hearing rattlesnakes at the G12 area, so I found this article about the snake and what to do. SSAR Herpetological Circular No. Distribution of the Timber Rattlesnake (Crotalus horridus) in North America. National Audubon Society Field Guide to North American Reptiles and Amphibians.

Gelbert. The ideal habitats for this rattlesnake are forested areas with rocky outcrops, dry ridges and second growth coniferous or deciduous forest. Assessment based on a new status report. Extinct (X) A wildlife species that no longer exists. In contrast, gravid females prefer less densely forested areas with 25% canopy closure, equal proportions of vegetation and leaf litter on the forest floor, frequent fallen logs and warmer climatic conditions (Ibid.). The last recorded sighting of a Canadian timber rattlesnake was in 1941, in the Niagara Gorge. It was an old specimen measuring 56 inches in length as this one was such an old specimen and as no others have been taken there in recent years, Mr. Patch was of the opinion that it was the last of its race. New York State Park Police report that the youth has undergone surgery. Foraging success and the ability of females to regain mass may be the main determinant of the length between successive reproductive events (Brown, 1991). Trilobites . 3. According to some researchers, the natural progression of forest succession may in fact be incompatible with the longterm survival of Timber Rattlesnake dens if the forest cover results in too much shade (Brown, 1993). 2001. He reportedly suffered a head injury during Monday's incident. That evening we drove up with the kids to see if we could see any for ourselves.

Identification: This slender snake has a beige backgroud with black brown or reddish blothes on its back.The belly of the snake is generally black and white checkered pattern. The combat dance of male Timber Rattlesnakes has been interpreted either as an expression of sexuality, or as a competitive interaction for food or dominance (Sutherland, 1958).

Odum, R.A. 1979. Unpublished data provided by Mike Oldham. Although the taxonomic status of the Timber Rattlesnake remains somewhat ambiguous in the eastern portion of its range (Brown and Ernst, 1986), it is generally accepted that the subspecific status of the canebrake rattlesnake is not warranted (Behler and King, 1996) and that Timber Rattlesnakes are monotypic (Collins and Knight, 1980). Inconnus et Mconnus: Amphibiens et Reptiles de la province de Qubec. The Niagara Gorge Trailhead Center will be on your left in 0.2 mile. Movements of gravid females are generally confined to thermally optimal gestation sites, such as open outcrop knolls in the vicinity of the den (Reinert and Zappalorti, 1988b; Brown, 1991). Today, road accidents and human destruction of habitat (either directly or indirectly), and deliberate killing of venomous snakes all contribute to the Timber Rattlesnakes population reduction. Martin, W.H. Opinion varies as to whether females give birth at den sites or at maternity rocks some distance away (Galligan and Dunson, 1979). Herpetologica 12: 326.
