This species occurs throughout the eastern and central United States, although it is locally extirpated in many areas. Laboratory and field studies suggest that newborn Timber Rattlesnakes are able to follow the scent trails of adults to communal hibernacula (Brown and MacLean, 1983; Reinert and Zappalorti, 1988a). University of North Carolina Press, Chapel Hill. Males migrate further than females, likely to search for mates. Herpetologica 14: 2324. 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. 605622. 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. 1996. Only found in Bergen Swamp near Rochester and. Natural Heritage/ Natural History Inc., Toronto. Others doubt the negative impacts of increased shading, and believe that selective tree removal as a management strategy may actually do more harm than good (Reinert, pers. 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. Overwintering body temperatures of Timber Rattlesnakes (Crotalus horridus) in northeastern New York. If the rattle becomes accidentally lost, the end of the tail remains blunt, never pointed (Ibid.). Herpetologica 4: 107114. The cessation of feeding was apparently induced by the development of large offspring. Another early account of a Timber Rattlesnake was of one collected by Captain G. Wilkinson near the end of Point Pelee in September 1818 and reported by Patch (1919, cited in Logier, 1925). Plourde, S.A., E.L. Szepesi, J.L. Mike Oldham provided me with pertinent information from the Ontario Herpetofaunal Summary. In Ontario, the Timber Rattlesnake has been assigned a rank of SX by the Natural Heritage Information Centre as apparently extirpated from Ontario (Oldham, 1997). The path will go slightly uphill, but nothing that requires too much exertion. They increased in size to 400550 mm SVL in their third year, 640740 mm in their fourth year and 760900 mm SVL by their fifth summer (Ibid.). However, the species has been extirpated from many states, including Louisiana, and it is a candidate for the US Fish and Wildlife Service's Endangered Species List. and R.T. Zappalorti. Behler, J.L. 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).

Other studies also support the contention that the Timber Rattlesnake consumes small mammals almost exclusively (Schmidt and Davis, 1941). Other habitat components are the summer habitat, where snakes move and forage, and transient habitat located in between summer habitat and the den (Brown, 1993). The predominant ambush position of this sitandwait predator involves coiling adjacent to a fallen log with the head positioned perpendicular to the long axis of the log. 1948. Copeia 4: 976981. Although the Timber Rattlesnake was proposed for listing under Appendix II of the CITES Convention in 1997, the proposal was not adopted because it was argued that international trade was minimal, and that the species would benefit more by increasing protection in the United States (Ibid.). Why are these snakes at such risk? Rattlesnakes are pit vipers. This ability could be crucial to the survival of newborns through their first winter, as they may be born a considerable distance away from any suitable hibernaculum (Reinert and Zappalorti, 1988a). Mating takes place in late summer (Martin, 1993) and young are born from late August to midSeptember (Galligan and Dunson, 1979).

Notes on a litter of young Timber Rattlesnakes. 253 pp. The western diamondback rattlesnake ( Crotalus atrox) is one of the best-known venomous snakes in North America. 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). 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). Herpetological Review 25(1): 3334. It arose from the need for a single, official, scientifically sound, national listing of wildlife species at risk. 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. Pit vipers are venomous snakes that have heat-sensing pits on the sides of their face that help them detect prey. It is preferable instead to check for snakes under rocks using mirrors and flashlights in order to minimize potential disturbance (Harwig, 1966). 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).

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). 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).

Rattlesnakes have a thick, broad body and a distinctive diamond-shaped head, although this is also true of some of our non-venomous snakes. Although some authors believe that colour phases are sex related (Ditmars, 1907), others have suggested that the variation is a thermoregulatory adaptation, as black specimens occur with greatest frequency in mountainous regions (Schaeffer, 1969).

Symptoms of Timber Rattlesnake poisoning include swelling, pain, respiratory difficulty, weakness, giddiness, haemorrhage, weak pulse or heart failure, nausea, vomiting, ecchymosis, heart pain, gastric disturbance, paralysis and unconsciousness or stupor (Hutchinson, 1929). Temperatures of freeliving New York Timber Rattlesnakes ranged from 12.5C to 33.3C from early June to early August (Brown et al., 1982). 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).
