Crotalus horridus (Timber Rattlesnake) longevity. Census data of whitefooted mice around a Pennsylvania rattlesnake den revealed a density estimate of 61 mice/ha (Galligan and Dunson, 1979). 1950. 1908. This species was last sighted in Canada in 1941. Because the larger snakes somewhat resemble rattlesnakes and they tend to do a lot of basking in the sun, they can scare people. Approximately half of a Timber Rattlesnakes daily activity cycle is spent basking, in order to maintain its preferred body temperature (Ibid.). Be prepared if you go hiking in the Gorge! I normally would. Photo by Rob Moore 1996. Rattlesnakes are found from southern Canada to central Argentina but are most abundant and diverse in the deserts of the southwestern United States and northern Mexico.

Death from a Timber Rattlesnake bite can occur in as little as 35 minutes (Hutchinson, 1929), particularly if the individual is allergic to pit viper venom (Parrish and Thompson, 1958). Toner. Data Deficient (DD)*** A category that applies when the available information is insufficient (a) to resolve a species eligibility for assessment or (b) to permit an assessment of the species risk of extinction. 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). Habitat destruction of Timber Rattlesnake sites includes blasting and fillingin of dens with concrete, logging, mining, and gas wells (Brown, 1993). Aldridge, R.D. 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.

A 5-year-old was rescued Monday after he and his mother jumped into the Niagara Gorge in Niagara Falls State Park. Only found in Bergen Swamp near Rochester and. and F.M. Thus the proposed status for COSEWIC is extirpated. There are two big factors that make this hike so hard. Keenlyne, K.D. Timber Rattlesnakes are large, oviviviparous, iteroparous, longlived and slow to mature, with a relatively long mean generation time (Brown, 1991). White Water Walk. If the rattle becomes accidentally lost, the end of the tail remains blunt, never pointed (Ibid.). Oldham, M.J. 1997. Herpetological Review 27(3): 144145. 1968. 1994b. This rattlesnake was found along the Niagara Escarpment, primarily in the Niagara area. Male Timber Rattlesnakes may use scent trailing to locate receptive females (Reinert and Zappalorti, 1988b). Weller, W. 1982. All available evidence indicates that the population size of the Timber Rattlesnake in Canada is zero.

The Niagara Gorge Trailhead Center will be on your left in 0.2 mile. 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). 1981. This species occurs throughout the eastern and central United States, although it is locally extirpated in many areas. Figure 1. According to Casper and Hay (2001), C. horridus is designated as extirpated in Maine and Rhode Island, endangered in Connecticut, Massachusetts, New Hampshire, New Jersey, Ohio, Vermont, and Virginia, threatened in Illinois, Indiana, Minnesota, New York, and Texas, a protected species in Maryland and Kansas, protected from take in Oklahoma and Pennsylvania and a protected wild animal in Wisconsin.

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. 1972. Brown, W.S., L. Jones and R. Stechert. Emergency crews performed life . Though they are mostly active by day, during a hot summer they may also be active at night. Gravid individuals comprised 84% of female Timber Rattlesnakes turned in during organized snake hunts in Pennsylvania (Reinert, 1990 in Brown, 1993). Opinion varies as to whether females give birth at den sites or at maternity rocks some distance away (Galligan and Dunson, 1979). Herpetological Review 25(4): 166. Villarreal, X., J. Bricker, H.K. As with all pit vipers, there is an opening visible between the eye and the nostril.

Because they are large and poisonous, Timber Rattlesnakes engender a large amount of human hostility (Plourde et al., 1989). and D.D. the Ministry of Natural Resources and Forestry tracks species at risk such as the Timber rattlesnake; try to develop an appreciation for snakes; they play an important role in our environment; whether in a field or in your backyard, if you come across a snake, keep in mind that you are much larger than it is and the snake is more afraid of you than you are of it, if you come across a snake, please dont try to capture it, handle it or kill it; snakes can be delicate and improper handling can cause serious injury; also, certain species are protected under legislation, which makes it illegal to harass, harm or kill them; be respectful and observe from a distance, watch for snakes that may be crossing roads between May and October; road mortality is a serious threat to snakes because they are slow moving, hard to see on the road and are sometimes intentionally run over; if it is safe to do so, help snakes across the road in the direction they were headed, private land owners have an important role to play in species recovery; you may be eligible for stewardship programs that support the protection and recovery of species at risk and their habitats, report poaching of snakes and other animals to, volunteer with a local nature club or provincial park to participate in surveys or stewardship work focused on species at risk, this rattlesnake is a sit and wait predator; it frequently coils up adjacent to a small mammal scent trail and may wait for several days for the unsuspecting small mammal, individuals return to the same hibernation site year after year, although the Timber rattlesnake is venomous, there are few records of human fatalities; More people die every year from insect stings than rattlesnake bites. Snake hunters report that it is not difficult to hunt out (i.e. The snake is slow to mature, has few snakelings in each litter and a low juvenile survival rate. Brown, pers. Newborn Timber Rattlesnakes have yellow on the lateral and ventral surfaces of their tails, but are not thought to use their tails as lures, as do other juvenile snakes with similar colouration (Neill, 1960). Timber Rattlesnake life history is characterized by delayed maturity, low reproductive potential and high longevity (Fitch, 1985). By Harold McNeil Buffalo News. An introduction to the reptiles and amphibians of the United States. 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.

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). . In Logier, 1925 (above). Fat stores are extremely diminished in postpartum females (Gibbons, 1972), with a mean mass difference of 306 g between gravid and postpartum females in a New York population (Brown, 1991). Sex ratio in a New Jersey brood was 1:1 (Odum, 1979). Herpetological Review 23(1): 26. Timber Rattlesnakes prefer areas not frequented by people (Ditmars, 1907; Anderson, 1965), although few such sites still exist (DeGraaf and Rudis, 1983). The locality was near an Indian village called Otinaoustettaoua, which is near presentday Waterdown, in Halton County (Ibid.). Bulletin of the Antivenin Institute of America 3: 4357. 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). 2001. Of a litter of twelve born to a New York snake, one was stillborn and an infertile egg was also deposited (Stewart et al., 1960). 1881. The severity of a snakebite depends on the amount of venom injected, the toxicity of the venom, and the depth and location of the bite (Minton, 1953). Movements of gravid females are generally confined to thermally optimal gestation sites, such as open outcrop knolls in the vicinity of the den (Reinert and Zappalorti, 1988b; Brown, 1991). WGRZ. A high-level whistleblower, who spoke on condition of anonymity, has revealed information that a den of Eastern Massasauga rattlesnakes, which are protected by law as a New York State endangered species, was observed in close proximity to the controversial construction site as recently as two years ago. Special Concern (SC)* A wildlife species that may become a threatened or an endangered species because of a combination of biological characteristics and identified threats. The preferred prey is rodents and other small mammals; however, the snakes also eat carrion, reptiles, amphibians, and birds, and their eggs. 1951. In Galligan and Dunson, 1979 (above).
