The only Canadian report of a possible Timber Rattlesnake bite, and subsequent fatality, was that of a soldier bitten during the Battle of Lundys Lane near Niagara Falls in 1814 (see Cook, 1999 for details). Herpetological Review 25(1): 3334. Other studies have also indicated that juvenile mortality is probably high (Odum, 1979). Bricker, J., L.M. There are two big factors that make this hike so hard. 9. Of the populations that remain, many have been reduced to 1520% of their numbers a few decades ago (Martin, 1983). Crotalus horridus (Timber Rattlesnake). White footed mice (Peromyscus leucopus) and redbacked voles (Clethrionomys gapperi) comprised the bulk of the diet of one sample, at 65% and 20% respectively (Ibid.).

Historical records are widely scattered and anecdotal and do not provide a clear picture of the species former abundance and distribution (Cook, 1999; see also Fig. Bites from rattlesnakes at the time of shedding and replacement of fangs indicate that the injection apparatus may not be fully functional at this time, as some victims bitten during this period did not exhibit any symptoms of poisoning (Hutchinson, 1929). In the nineteenth century, hunting parties would attack den sites and kill all the snakes that could be found. Time: 1 - 2 hours. Of a litter of twelve born to a New York snake, one was stillborn and an infertile egg was also deposited (Stewart et al., 1960). The foraging behaviour of Timber Rattlesnakes was studied in detail in Pennsylvania (Reinert et al., 1984). Photo by Rob Moore Patch, C.L. Male Timber Rattlesnakes reach maturity at an average age of 5.3 years in northeastern New York (Aldridge and Brown, 1995) and 4 years in South Carolina (Gibbons, 1972).

Western Diamondback Rattlesnake. The Journal of Heredity 87(2): 152155. In summer, the preferred habitat for males and nonpregnant females is a wellcanopied forest with thick vegetation, whereas pregnant females prefer a more open forest with many fallen logs and a warmer climate. G.P. Similarly in Virginia, the three leading foods were mice, chipmunks and cottontail rabbits (Uhler et al., 1939). During follicle development, females either ate more, or were more efficient at converting food to stored visceral fat. 1950. per adult.

Extirpated species and their habitat are protected if the species are again found in Ontario. The snake feeds on rodents and other small mammals. The females reproduce once about every three years. Because females do not mature until about eight years old and reproduce on average only once every three years (Martin, 1993), most females will give birth to no more than five broods throughout their lifetime, assuming a lifespan of 22 years (Brown, 1991).

Relict populations of Timber Rattlesnakes were known to have persisted on South Bass Island and on the Catawba peninsula of Ohio until at least 1951 (Langlois, 1951). A population is defined by its den, which is critical to the survival of the entire population (Brown, 1993). Journal of Herpetology 16(2): 145150. 1956. Palmer, J.R. Bailey and J.R. Harrison.

Cook, pers. Casper, G. and R. Hay. Distribution and status of the herpetofauna of central region, OMNR. In Missouri, the Timber Rattlesnake population is gradually being reduced, and the species has been practically exterminated in some areas where it was formerly common (Anderson, 1965). 1996. Contrary to popular belief, rattlesnakes cannot be aged directly by counting the number of segments in the rattle. There are many ways to contact the Government of Ontario. : extirpated 1993 Brown: probably extirpated [from Ontario]1999 Cook: almost certainly extirpated in Canada.

Though they are mostly active by day, during a hot summer they may also be active at night. Hutchinson, R.H. 1929. Mountain Lion . It is almost a certainty that the Timber Rattlesnake has been extirpated, as demonstrated by the following quotes: 1881 Garnier: rapidly becoming extinct [in Ontario] 1908 Nash: formerly common and generally distributed throughout the province now nearly extinct 1939 Logier: that the early distribution of this snake in Ontario was more extensive seems likely 1982 Weller: may very well have been extirpated in Ontario 1984 Cook: the last specimen taken in Ontario was from Niagara Glen in 1941 1989 Johnson: extirpated from Ontario 1989 Plourde et al. Neill, W.T. http://www.mpm.edu/collect/vertzo/herp/timber/htm. Niagara Gorge Scooter Tour. 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. There is only a single recorded incident in Canada of a Timber Rattlesnake bite resulting in death -- a soldier in the Battle of Lundys Lane in 1814. A Louisiana Timber Rattlesnake lived 36 years, 7 months and 27 days in captivity, reaching a total length of 1770 mm (Cavanaugh, 1994). Each of the US states in which this snake is found affords the species some degree of protection, however, the level varies from state to state. Herpetologica 14: 2324. Historical depletion of Timber Rattlesnake colonies in New York State. The snake uses the rattle to warn potential aggressors to back off or to distract prey. 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. Ovulation occurs from late May to early June, while maximum spermatogenesis is reached in July, continuing through September (Aldridge and Brown, 1995; Martin, 1993). The Niagara region has one of the largest inhabitations of reptiles and amphibians in the country. The climb up Shortoff Mountain is 1,500 feet in about a mile. This is a shy and secretive species and reports of Timber Rattlesnakes biting humans are rare (Ditmars, 1907; Brown, 1981). Journal of the Pennsylvania Academy of Sciences 64: 136144. Cook, F.R. 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.

Conserving the Timber Rattlesnake. It stretches 11 kilometers (6.8 miles) north of Niagara Falls. It can grow to almost two metres long. 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). On June 5, 2003, the Species at Risk Act (SARA) was proclaimed. The Midget Faded Rattlesnake is only found in the Flaming Gorge area, but it's worth noting because it is far more deadly than most other rattlesnakes. These features include slow maturation rates, low reproductive output, low juvenile survival and slow population replacement rate (Harding, 1997). Males and nongravid females utilize forest habitat with greater than 50% canopy closure, thick surface vegetation and few fallen logs (Reinert and Zappalorti, 1988b). Because the larger snakes somewhat resemble rattlesnakes and they tend to do a lot of basking in the sun, they can scare people. Herpetologica 4: 107114. Human exploitation, through bounty hunting, commercial collecting and sport hunting, is the leading cause of Timber Rattlesnake decline throughout the species range (Galligan and Dunson, 1979; Brown, 1993).

A comparison of movement patterns: native vs. translocated Timber Rattlesnakes (Crotalus horridus). Timber Rattlesnakes collected during organized roundups are often released far away from their point of capture, and this action most likely leads to the death of the snake, because of its unfamiliarity with its surroundings (Brown, 1993). 17: 1520 ) studied the sexual differences of feeding was apparently induced by the 2010 US Environmental protection &...
