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). The Timber rattlesnake is a greyish-brown to yellow, thick-bodied snake with a triangular-shaped head and dark markings that start as blotches on the front of the body but are fused together to form crossbands (chevron-shaped markings) along most of the body and the tail. and J.L.

Timber Rattlesnakes (Crotalus horridus) of the Pine Barrens: their movement patterns and habitat preference. This is true for two reasons; first, a segment is added each time a snake sheds (not necessarily once a year) and second, segments are continually being broken off most wildcaught individuals have between five and nine segments in their rattles (Schmidt and Davis, 1941). The 5-year-old boy who survived a 90-foot fall into the Niagara Gorge at Niagara Falls State Park on Monday after his mother jumped with him from above is in critical condition following.

Royal Ontario Museum of Zoology, Handbook No. Distribution of the Timber Rattlesnake (. Timber Rattlesnakes have been employed as study subjects to test a number of novel techniques. The rattle is the most obvious behavior of these snakes, apparently used when the individual feels angry or threatened. Transactions of the 4th North American wildlife conference. Because of their gregarious nature, hundreds were sometimes killed in a raid on a single den (Schmidt and Davis, 1941). In both provinces, the snakes were exterminated by hunting parties killing the snakes at their dens, habitat loss, and hog farming using pigs to eradicate the snakes, until they had been wiped out across Canada.

Explore the area of the footbridge and you'll be able to see a bit of Rattlesnake Gorge. The head is roughly triangular and abruptly distinct from the neck (Anderson, 1965). Weller, W. 1982. The pit and the vertical nature of the pupil are characteristics that can be used to distinguish the Timber Rattlesnake from similarly patterned nonvenomous snakes, such as the eastern fox snake (Elaphe gloydi)(Harding, 1997). It's common for rattlesnakes to be mistaken for gopher snakes, so you need to be able to tell them apart. Mean age of first reproduction for females averaged 7.8 years in northwestern Virginia (Martin, 1993), 6 years in South Carolina (Gibbons, 1972), four years in Kansas (Fitch, 1985) and 910 years in northeastern New York (Brown, 1991).

Ovulation occurs from late May to early June, while maximum spermatogenesis is reached in July, continuing through September (Aldridge and Brown, 1995; Martin, 1993). Introduction to Canadian Amphibians and Reptiles. The natural lifespan of the Timber Rattlesnake in the northern part of its range is approximately 25 years (Brown, 1993). Adult sizes range from approximately one to two meters. List of the Reptilia of Ontario. Jensen was moving cows when he spotted a rattler. Timber Rattlesnakes near the northern extent of their range typically hibernate for 7.4 months, with the active period extending from early May through late September (Brown, 1991). Natural Heritage Resources of Ontario: amphibians and reptiles. National Museum of Natural Sciences, National Museums of Canada, Ottawa, Ontario. These demographic characteristics also make the Timber Rattlesnake a species in which there is little natural harvestable surplus of adult individuals (Brown, 1993). 365 pp. 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). 1993. Historically, they have been subject to human exploitation, such as bounty hunting, collection and sport hunting. Sheds can be measured directly by painting the rattle and then counting unpainted segments upon recapture (Brown, 1991). Foraging success and the ability of females to regain mass may be the main determinant of the length between successive reproductive events (Brown, 1991). 1939. They are seasonally migratory -- from the den site to the summer habitat and back again. 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). 1997. CW6914/1112002EINISBN 0662318803. Harwig, S.H. Timber Rattlesnakes are considered the most mildmannered of any of the North American rattlesnakes, and individuals usually do well in captivity (Ditmars, 1907; Anderson, 1965; Morris, 1974). This is where summer days are typically hot and dry. Field observation of the association of adult and neonatal Timber Rattlesnakes, Crotalus horridus, with possible evidence for conspecific trailing. 1476 pp. Timber Rattlesnakes prefer areas not frequented by people (Ditmars, 1907; Anderson, 1965), although few such sites still exist (DeGraaf and Rudis, 1983). The Niagara Gorge is an 11-kilometer-long gorge that divides Canada and the United States, carved out by the great Niagara River thousands of years ago. Jensen, J.B., B.W. Mating takes place in late summer (Martin, 1993) and young are born from late August to midSeptember (Galligan and Dunson, 1979). Rattlesnakes are deaf to the sound of their own rattles, and are thought to use them when angry or threatened (Ditmars, 1907). 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). 1982. ): 198. A 5-year-old was rescued Monday after he and his mother jumped into the Niagara Gorge in Niagara Falls State Park. Schaeffer, G.C. Identifying a Gopher snake starts by approaching it with caution.

HERP Bulletin of the New York Herpetological Society 15(1): 2735. Because the larger snakes somewhat resemble rattlesnakes and they tend to do a lot of basking in the sun, they can scare people. A 5-year-old Illinois boy remains in critical condition . and W.A. An unrecorded food item of the Timber Rattlesnake. 2. The practice of paying bounties on Timber Rattlesnakes in New York ended in 1971 under the Fish and Wildlife Law (Brown, 1981). Small mammals are the favoured prey; different species are consumed in proportion to their prevalence at the site. As with most other reptiles, roadkill is an additional aspect of humaninduced mortality (Martin et al., 1992; Dundee, 1994b; Jensen et al., 1994). The winter habitat is primarily the den, which is located on a south facing rocky outcrop. 1919. Rattles are vibrated sideways at about 48 cycles per second (Schmidt and Davis, 1941). The Western New York Land Conservancy has been leading the initial efforts to restore and enhance the natural habitat on 37 acres of land along the gorge with an initial $1 million in funding from the New York Power Authority via funding from the New York Power Authority via the Niagara Greenway Commission Ecological Standing Committee. Ron Brooks and Glenn Barrett supplied advice and technical assistance. The estimated area needed for a viable population is 50 km. and F.M. From Oldham and Weller, 2000. As such, they have the capacity to contribute significantly to our knowledge of covariation in life history traits (Ibid.). The rattlesnake has such a legacy there that in the late 20th Century there was a professional lacrosse team named the Rattler's. This despite the rattlesnake has not been seen in the City of Rochester for many decades prior. Be prepared for a chilly breeze, whirlpool rapids, and watching gallons of water rushing to the trough.

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. The Timber Rattlesnake is a sit and wait predator. Edgren, R.A. Jr. 1948. Endangered (E) A wildlife species facing imminent extirpation or extinction. American Zoologist 28(4): 195A. Comstock Publishing Associates, Cornell University Press, Ithaca, New York. Male snakes mature at a mean age of 4 years, while females mature at a mean age of 6 years, depending on the location of the population. 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). It is therefore assumed that the size of the Canadian population of Timber Rattlesnakes is zero. Since 1996, the Nature Conservancy has ranked the Timber Rattlesnake G5 (Oldham, 1997). 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). Alfred A. Knopf, New York. An area of approximately 50 km of suitable habitat is required to sustain a population (Brown, 1993). Crotalus horridus (Timber Rattlesnake). DeGraaf and W.R. Danielson. 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). 1966. The larger division, adjoining the left, or Canadian, bank, is Horseshoe Falls; its height is 188 feet (57 metres), and the length of its curving crest line is about 2,200 feet (670 metres).

Smith, Kim. The minimum viable population size for Timber Rattlesnake recovery is estimated at 30 to 40 individuals with an even age distribution and at least four or five mature females per den (Brown, 1993). Not at Risk (NAR)** A wildlife species that has been evaluated and found to be not at risk of extinction given the current circumstances. A 5-year-old boy was rescued and his mother died after the two jumped 90 feet into the Niagara Gorge at Niagara Falls State Park on Monday, officials said. Extinct (X) A wildlife species that no longer exists. Committee on the Status of Endangered Wildlife in Canada. Growth rates and size of newborns appears to be highly variable geographically, and Brown (1991) presents a table summarizing both growth rates and minimum age of first reproduction of Timber Rattlesnakes throughout their range. 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). Martin, W.H. Recently milked rattlesnakes are also capable of producing serious bites, and there is no evidence that previously exposed victims develop any sort of immunity through antibody production (Parrish and Thompson, 1958). One Utah rattlesnake population heavily hunted for only one year had still not recovered 12 years later (Woodbury and Hansen, 1950 cited in Galligan and Dunson, 1979). 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.). per adult.
