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). Saenz, D., S.J. All available evidence indicates that the population size of the Timber Rattlesnake in Canada is zero. 1966. Female snakes usually do not eat during gestation. Observations on gravid females in captivity also indicated that the snakes did not feed during gestation (Odum, 1979).

Weller. 1983. 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). There are no known populations of the Timber Rattlesnake in Canada and the last sighting was almost sixty years ago. Female reproductive ecology in a northern population of the Timber Rattlesnake, Crotalus horridus. Copeia 1950: 100107. The famous rattle noise comes from . Martin, W.H., J.C. Mitchell, and R. Hoggard 1992. ), 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). Hudson, R. and G. Carl. Barton, A.J. In general, they are very mildmannered and will not strike unless provoked. It also provides some amazing unobstructed views of the southernmost section of the Niagara Gorge. Brown, W.S. Extirpated (XT) A wildlife species no longer existing in the wild in Canada, but occurring elsewhere. 1908. Herpetologica 6(3): 6670. 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). Jensen was moving cows when he spotted a rattler. The Timber Rattlesnake is a heliothermic species, with the ability to regulate its temperature by radiation absorption throughout its daytime activities (Odum, 1979). University of Toronto Press, Toronto, Ontario. data). Herpetologica 4: 107114. 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. The Niagara Region is home to 14 snake species excluding those who have become extinct. The last state lifted the bounty on Timber Rattlesnakes in 1971. 1939. The timber rattlesnake (Crotalus horridus) is the only wide-ranging woodland rattlesnake of deciduous forests in eastern North America (Smith 2001). 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. Copeia 1953: 212215. Since 1996, the Nature Conservancy has ranked the Timber Rattlesnake G5 (Oldham, 1997). In a Timber Rattlesnake population in New York, male roadkills outnumbered female roadkills 3.9:1.0, and humancaused mortality rates in general were much higher for males than for females (13:1) (Aldridge and Brown, 1995). Many translocated snakes immediately leave the area in which they are released (Galligan and Dunson, 1979). The ideal habitats for this rattlesnake are forested areas with rocky outcrops, dry ridges and second growth coniferous or deciduous forest. Populations of Timber Rattlesnakes are limited in the northern parts of their range by a small number of suitable nest sites. 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. 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. The Massasauga rattlesnake has nine large scales on its head, whereas the Timber Rattlesnake has many small scales on its head. An unrecorded food item of the Timber Rattlesnake. Journal of Herpetology 2: 107-112. The locality was near an Indian village called Otinaoustettaoua, which is near presentday Waterdown, in Halton County (Ibid.). Odum, R.A. 1979. 2. Have fun, hike safe, be respectful, be cautious and be aware in Oregon's rattlesnake terrain! 1956. Genetic variation and gene flow within and between local populations of the Timber Rattlesnake, Crotalus horridus. Foregoing reproduction in some years is apparently necessary to allow females to gain weight and store yolk protein in the developing eggs (Galligan and Dunson, 1979; Brown, 1981). 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). As with most other reptiles, roadkill is an additional aspect of humaninduced mortality (Martin et al., 1992; Dundee, 1994b; Jensen et al., 1994). Penalties can range as high as a $5,000 fine and/or imprisonment for 180 days, in addition to a restitution payment of $2,000 per animal killed (Ibid.). The Timber Rattlesnake has many small scales, whereas the Massasauga has nine large scales (Ibid.). National Museum of Natural Sciences, National Museums of Canada, Ottawa, Ontario. Hutchinson, R.H. 1929. 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). Pp. 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. Niagara Gorge Scooter Tour. 2000. Pp. Logier, E.B.S. . They can live up to 25 years, reaching their adult size by about 45 years. 1981. Emergency crews performed life . 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). Batrachians and reptiles of Ontario. Davis. Journal of Herpetology 16(2): 145150. Timber Rattlesnakes produce stillborn young and abort infertile eggs at a frequency of about 20% (W.S. Department of Education, Toronto, Ontario. Figure 2. and W.S. 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). Rattles are vibrated sideways at about 48 cycles per second (Schmidt and Davis, 1941). 22 pp. Male Timber Rattlesnakes may use scent trailing to locate receptive females (Reinert and Zappalorti, 1988b). Timber Rattlesnakes generally begin to rattle when approached within 12 m (Barbour, 1950). Natural Heritage/ Natural History Inc., Toronto. In the northern parts of their range females reproduce on average every three years (Brown, 1993; Martin, 1993), with 1075% of females in a population reproducing in any given year (Galligan and Dunson, 1979). Field book of snakes in United States and Canada. 1996. 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. and F.W. Distribution of the Timber Rattlesnake (Crotalus horridus) in Ontario. Threatened (T) A wildlife species likely to become endangered if limiting factors are not reversed. Males are much longer and heavier than the females. The pits enable the snake to sense warm-blooded animals and even tell the size of the animal. Duran. Distance: 4 km. A 5-year-old was rescued Monday after he and his mother jumped into the Niagara Gorge in Niagara Falls State Park. COSEWIC. and F.M. Timber Rattlesnakes may swim across lakes during their seasonal migrations (Neill, 1948), and small Timber Rattlesnakes have been found as high as 9 m in trees (Saenz et al., 1996). Look at the eyes. They have been extirpated from the states of Maine and Rhode Island, and may be close to extirpation in New Hampshire (Brown, 1993). Brown. 3. Journal of Herpetology 29(3): 399407. New York State Park officials received multiple calls at approximately 12:30 p.m. regarding a woman and child who had fallen into the gorge in the area near the Cave of the Winds entrance at Niagara Falls State Park. Adventure Tours. 1983. Committee on the Status of Endangered Wildlife in Canada. Ditmars, R.L. 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.). The colonial nature of Timber Rattlesnakes was a factor contributing to their extirpation from Canada by humans (Plourde et al., 1989). 1939. Most rattle growth occurs within the first four sheddings, and the increase in diameter of successive segments is less than 5% after the seventh ecdysis (Fitch, 1985). The natural lifespan of the Timber Rattlesnake in the northern part of its range is approximately 25 years (Brown, 1993). 1950. White Water Walk.

Sex independent ground colour in the Timber Rattlesnake, Crotalus horridus horridus. A snake den in Tintic Mountains, Utah. Variations of these colour phases occur in the western and southern portions of its range (see canebrake rattlesnake, below) (Conant and Collins, 1991). COSEWIC assessment and update status report on the Timber Rattlesnake Crotalus horridus in Canada. Though they are mostly active by day, during a hot summer they may also be active at night. A study of the variation in eastern Timber Rattlesnakes, Crotalus horridus Linnae (Serpentes: Viperidae). Morris, P.A. and D.D. Villarreal, X., J. Bricker, H.K. It's common for rattlesnakes to be mistaken for gopher snakes, so you need to be able to tell them apart. Copeia 1988(4): 964978. 124 pp. Bushar, H.K. Herpetological Review 27(3): 145. Reason for designationThe 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. Greene and J.B. Friedlaender. Niagara Glen Add to Itinerary. In the nineteenth century, hunting parties would attack den sites and kill all the snakes that could be found. Niagara River Habitat Conservation Strategy Completed in 2014,this document identifies critical habitats and priority actions for the 900,000+ acre Niagara River watershed. Herpetological Review 16(1): 2829. The combat dance of the Timber Rattlesnake. The snake feeds on rodents and other small mammals. Collins. Other common names include American viper, bastard rattlesnake, black rattlesnake, common (timber) rattlesnake, eastern rattlesnake, great yellow rattlesnake, mountain rattlesnake, mountain timber rattler, North American (horrid) rattlesnake, Northern banded rattlesnake, northern rattlesnake, pit viper, rock rattlesnake, velvet tail, yellowish brown rattlesnake and yellow rattlesnake (Wright and Wright, 1957). In Kentucky, we have four venomous snakes: the timber rattlesnake, pygmy rattlesnake (mainly found . extirpate) an entire den (Galligan and Dunson, 1979). Translocated males have significantly larger activity ranges, range lengths and mean distances moved per day than native males (Rupert and Reinert, 1992). SARA establishes COSEWIC as an advisory body ensuring that species will continue to be assessed under a rigorous and independent scientific process. Reinert, H.K. Niagara is far from the highest waterfall in the world, or even in New York. 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). The foraging behaviour of Timber Rattlesnakes was studied in detail in Pennsylvania (Reinert et al., 1984). Similarly, in a New Jersey litter of 13 born in captivity, one snakeling was born dead, and another had a birth defect that would prevent it from eating (Odum, 1979). COSEWIC Status Report on the Timber Rattlesnake Crotalus horridus in Canada 2001. Reptiles and amphibians: Eastern and Central North America (3rd Edition). Small mammals are the favoured prey; different species are consumed in proportion to their prevalence at the site. Timber Rattlesnakes in the Big Black Mountain area of Kentucky play a prominent part in certain religious rites in the area (Barbour, 1950). Ron Brooks and Glenn Barrett supplied advice and technical assistance.
