She is currently working toward an M.Sc. The Timber Rattlesnake was among the first snakes to be officially designated as an endangered species under Ontarios Endangered Species Act, 1973 (Weller, 1982). The Timber Rattlesnake once occupied much of the Niagara Escarpment and other regions of southern Ontario, but has not been seen in the province since 1941 despite intensive searches and its easy identification.

The milksnake usually never reaches more than one meter in length (Yagi et al., 2009). Foraging success and the ability of females to regain mass may be the main determinant of the length between successive reproductive events (Brown, 1991).

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. Hibernation in the northern parts of the Timber Rattlesnakes range occurs in the cracks of rocky ledges, usually facing south (Odum, 1979). Gravid females are particularly susceptible to persecution due to their preference for more open habitats and the predictability with which they occupy specific sites (Brown, 1993). The first shedding of maxillary fangs takes place at a very early age, as evidenced by the fact that newborns have been found with fangs in the functional position (Barton, 1950). A comparison of movement patterns: native vs. translocated Timber Rattlesnakes (Crotalus horridus). 2000. A population is defined by its den, which is critical to the survival of the entire population (Brown, 1993). The locality was near an Indian village called Otinaoustettaoua, which is near presentday Waterdown, in Halton County (Ibid.). Handbook of snakes of the United States and Canada, Vol. 1996. Venom is clear and watery in newborns, becoming bright yellow and concentrated as the snake matures (Johnson et al., 1968). Logier, Frank Ross, Craig Campbell and James Kamstra), but no Timber Rattlesnakes have been found (Ibid.). decimation of population through hunting, road-kills, persecution because of discrimination against venomous snakes. A mother is dead and her 5-year-old son is in critical condition after they both fell "approximately 90 feet" into the Niagara Gorge at the Niagara Falls State Park earlier this week, authorities . Characteristics of venom from the rattlesnake Crotalus horridus atricaudatus. Jensen, J.B., B.W. Timber Rattlesnakes generally begin to rattle when approached within 12 m (Barbour, 1950). A naturalist working for the Western New York Land Conservancy as part of the "Restore the Gorge" project discovered a rare species of cicada clinging to a Carolina rose in the Niagara gorge . Timber Rattlesnakes once occurred throughout the Carolinas and Virginia, but they have been eliminated from areas of extensive deforestation and human settlement (Martof et al., 1980). Sheds can be measured directly by painting the rattle and then counting unpainted segments upon recapture (Brown, 1991). 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).

Rattlesnakes documented in Grand Canyon National Park Gravid females did not contain any food items, while 30.3% and 35.0% of males and nongravid females, respectively, contained at least one food item. Schmidt, K.P. The colouration at the tip of the tail becomes noticeably dark. Herpetologica 47(1): 101115. In Logier, 1925 (above). The mean maximum migratory distance from the den was 4.07 km for males and 2.05 km for females in northeastern New York (Brown, 1993). The Timber Rattlesnake has already been designated as extirpated in Ontario by the Nature Conservancy (Oldham, 1997), and the vast majority of experts agree that the Timber Rattlesnake no longer exists in Canada. ** Formerly described as Not In Any Category, or No Designation Required.*** Formerly described as Indeterminate from 1994 to 1999 or ISIBD (insufficient scientific information on which to base a designation) prior to 1994. 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. Timber Rattlesnakes can be confused with Massasauga rattlesnakes and some nonvenomous species, such as the fox snake.
