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). They can live up to 25 years, reaching their adult size by about 45 years. Rare and endangered reptiles in Ontario (Part I). It stretches 11 kilometers (6.8 miles) north of Niagara Falls.

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). Ron Brooks and Glenn Barrett supplied advice and technical assistance. 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). A production note will be provided if additional information on the status report history is required. Putnams Sons, New York. Opinion varies as to whether females give birth at den sites or at maternity rocks some distance away (Galligan and Dunson, 1979). Photo by Rob Moore In addition, it is designated as endangered by both the Ontario Ministry of Natural Resources Committee on the Status of Species at Risk in Ontario and the Ontario Endangered Species Act. Journal of Herpetology 29(3): 399407. 1950. 264 pp. 1985. Until recently, southern populations of the Timber Rattlesnake were widely recognized as a separate subspecies, the canebrake rattlesnake (C. h. atricaudatus) (Schmidt and Davis, 1941; Anderson, 1965; Martof et al., 1980). Temperatures of freeliving New York Timber Rattlesnakes ranged from 12.5C to 33.3C from early June to early August (Brown et al., 1982). They are very loyal to their den site and will return year after year. 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). 1958. 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 5-year-old was rescued Monday after he and his mother jumped into the Niagara Gorge in Niagara Falls State Park. Today, road accidents and human destruction of habitat (either directly or indirectly), and deliberate killing of venomous snakes all contribute to the Timber Rattlesnakes population reduction. Continuous disturbance of this sort may eventually cause snakes to abandon these sites altogether (Ibid.). State Park Police said their dispatchers received "multiple calls", at about 12:30 p.m., reporting that an "adult female and her child fell into the Niagara Gorge between Terrapin Point and the Cave of the Winds." In the nineteenth century, hunting parties would attack den sites and kill all the snakes that could be found.

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). This weight loss represents 41% of female body weight (Galligan and Dunson, 1979). A population is defined by its den, which is critical to the survival of the entire population (Brown, 1993). That evening we drove up with the kids to see if we could see any for ourselves. The Ministry of the Environment, Conservation and Parks works to protect and sustain the quality of Ontarios air, land, and water. All available evidence indicates that the population size of the Timber Rattlesnake in Canada is zero. Protected public lands and privately owned nature preserves have contributed significantly to the conservation of Timber Rattlesnakes where they still exist (Ibid. 1981. We also coordinate Ontarios actions on climate change in the name of healthier communities, ecological protection and economic prosperity. 1994. Niagara Gorge Scooter Tour.

An introduction to the reptiles and amphibians of the United States. Amphibians and reptiles of the Carolinas and Virginia. 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). Due to their appearance and frightening actions, people assume snakes to be dangerous (Edward & Foote, 1979). Aldridge, R.D. Brown, W.S. 1105 pp. Quarterly Journal of the Florida Academy of Sciences pp. 1996. Fitch, H.S. The cessation of feeding was apparently induced by the development of large offspring. COSEWIC Secretariatc/o Canadian Wildlife ServiceEnvironment CanadaOttawa, ONK1A 0H3, Tel. Granitic escarpments and ledges with accumulations of talus are common features of den sites (Brown, 1991), the majority of hibernacula being found on south facing slopes (Galligan and Dunson, 1979). Rattlesnakes have a thick, broad body and a distinctive diamond-shaped head, although this is also true of some of our non-venomous snakes. 472 pp. comm.

The area around Niagara Falls is home to a wide variety of wildlife, including mammals, bird, reptiles and amphibians. Migration distances of males in general are greater than those of females because they actively engage in seeking mates (Reinert and Zappalorti, 1988b). 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). Similarly in Virginia, the three leading foods were mice, chipmunks and cottontail rabbits (Uhler et al., 1939). 1974. The Timber Rattlesnake is a heliothermic species, with the ability to regulate its temperature by radiation absorption throughout its daytime activities (Odum, 1979). The head is triangular with a distinct neck. The mean summer temperature of a Timber Rattlesnake is 26.9C and the mean winter (hibernation) temperature is 10.0C. 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). 2. 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). Variation in venom samples from copperheads (Agkistrodon contortrix) and Timber Rattlesnakes (Crotalus horridus).

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 of their gregarious nature, hundreds were sometimes killed in a raid on a single den (Schmidt and Davis, 1941).
