The head is triangular with a distinct neck. The ideal habitats for this rattlesnake are forested areas with rocky outcrops, dry ridges and second growth coniferous or deciduous forest. To have a better experience, you need to: Extirpated means the species lives somewhere in the world, and at one time lived in the wild in Ontario, but no longer lives in the wild in Ontario. Rattlesnakes are not usually found above 6,000 feet in . Langlois, T.H. Biological Conservation 15: 1358. The designation of status for the Timber Rattlesnake is quite straightforward: it has not been reported in this country in almost 60 years. The milksnake usually never reaches more than one meter in length (Yagi et al., 2009). 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 . To discriminate between timber and Massasauga rattlesnakes (Sistrurus catenatus), the number and size of the scales on the dorsal surface of the head can be informative. Rare. 1996.

From 1996 to 1998, she conducted field work on a variety of taxonomic groups, including marine invertebrates and sea ducks, marine fishes, reptiles, waterfowl and mammals. 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). At the time of European settlement, the Timber Rattlesnake was found in 30 states and was extremely abundant in areas of suitable habitat (Casper and Hay, 2001). 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. Favourite basking rocks are used year after year, and may attract many snakes at one time (Harwig, 1966). and W.S. 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). Adult sizes range from approximately one to two meters. Herpetological Review 16(1): 2829. Committee on the Status of Endangered Wildlife in Canada. First, the trails are steep.

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). The practice of paying bounties on Timber Rattlesnakes in New York ended in 1971 under the Fish and Wildlife Law (Brown, 1981). The foraging behaviour of Timber Rattlesnakes was studied in detail in Pennsylvania (Reinert et al., 1984). Several biological traits of the Timber Rattlesnake greatly reduce its ability to recover from largescale losses of adults in a population. The Niagara Gorge Trailhead Center will be on your left in 0.2 mile. ), although some public lands may have been managed with the goal of eliminating Timber Rattlesnakes because of fears that their presence might deter visitors (Cook, 1999). Copeia 1960: 336337. 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. Herpetological Review 27(3): 133134. Historically, they have been subject to human exploitation, such as bounty hunting, collection and sport hunting. 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). Populations of Timber Rattlesnakes are limited in the northern parts of their range by a small number of suitable nest sites. Committee on the Status of Endangered Wildlife in Canada. 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). Timber Rattlesnake life history is characterized by delayed maturity, low reproductive potential and high longevity (Fitch, 1985). 1988. Crotalus horridus (Timber Rattlesnake) coloration.

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). The rattle is the most obvious behavior of these snakes, apparently used when the individual feels angry or threatened. Because of their gregarious nature, hundreds were sometimes killed in a raid on a single den (Schmidt and Davis, 1941).

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). Barton, A.J. 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. Since 1996, the Nature Conservancy has ranked the Timber Rattlesnake G5 (Oldham, 1997).

In a letter to Francis Cook dated 15 September 1963, Frank Darroch described the changes to the habitat where he collected the last known Timber Rattlesnake in Ontario in 1941 (Cook, 1999): The place where I found the snake has in the last ten years been entirely destroyed as a habitat, by the new road put in for the new hydro power plant. Thus, the persistence of Timber Rattlesnakes in that area of the Niagara region seems highly unlikely. 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. Distribution of the Timber Rattlesnake (Crotalus horridus) in Ontario. American Zoologist 28(4): 195A. Hibernation of amphibians and reptiles in Richmond County, Georgia. Other studies also support the contention that the Timber Rattlesnake consumes small mammals almost exclusively (Schmidt and Davis, 1941). 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. Mike Oldham provided me with pertinent information from the Ontario Herpetofaunal Summary. 1115 In Manual of Vertebrates of Ontario. Ohio Conservation Bulletin 15: 14.

The most recent confirmed records of this rattlesnake in Ontario are from the Niagara Gorge in the 1940s. Foraging success and the ability of females to regain mass may be the main determinant of the length between successive reproductive events (Brown, 1991). Rattlesnake Point near Milton, Ontario The Niagara River over thousands of years carves the Niagara Gorge over and through the Niagara Escarpment The Niagara Escarpment is a long escarpment, or cuesta, in Canada and the United States that runs predominantly east-west from New York through Ontario, Michigan, Wisconsin, and into Illinois. and D.D.

Thus the proposed status for COSEWIC is extirpated. 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 earliest record of Timber Rattlesnakes in what is now Ontario dates back to September 1669, where there is a reference in the journal of Rene de Brehart Galine, who was attached to M. de La Salles party (Logier, 1939). However, none of these reports has ever been fully substantiated, and the adjacent populations in New York State (which may have acted as a source population for Quebec) have been extirpated (see Cook, 1999 and Mlanon, 1950 for more detailed summaries of Quebec reports). xxx + 450 pp. Occasional papers of the Museum of Natural History, University of Kansas 118: 1-11.
