The western diamondback rattlesnake ( Crotalus atrox) is one of the best-known venomous snakes in North America. White footed mice (Peromyscus leucopus) and redbacked voles (Clethrionomys gapperi) comprised the bulk of the diet of one sample, at 65% and 20% respectively (Ibid.). The snake is slow to mature, has few snakelings in each litter and a low juvenile survival rate. One Utah rattlesnake population heavily hunted for only one year had still not recovered 12 years later (Woodbury and Hansen, 1950 cited in Galligan and Dunson, 1979). 2000. Rattlesnakes have a thick, broad body and a distinctive diamond-shaped head, although this is also true of some of our non-venomous snakes. Identifying a Gopher snake starts by approaching it with caution.

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). Copeia 1988(4): 964978. Natural Heritage Resources of Ontario: amphibians and reptiles.

Historically, they have been subject to human exploitation, such as bounty hunting, collection and sport hunting. Martof, B.S., W.M. Migration distances of males in general are greater than those of females because they actively engage in seeking mates (Reinert and Zappalorti, 1988b). Explore the Niagara Gorge Trail System, made up of a series of smaller trail sections that parallel the Niagara River Gorge, offering some of the best hiking and biking trails in Niagara Falls USA. In contrast, gravid females prefer less densely forested areas with 25% canopy closure, equal proportions of vegetation and leaf litter on the forest floor, frequent fallen logs and warmer climatic conditions (Ibid.). Ernst. Crotalus horridus (Timber Rattlesnake). Herpetologica 25: 6566. Growth rate slows after maturity (Galligan and Dunson, 1979), and adult total length ranges from 9001890 mm (Conant and Collins, 1991). Favourite basking rocks are used year after year, and may attract many snakes at one time (Harwig, 1966). Gravid individuals comprised 84% of female Timber Rattlesnakes turned in during organized snake hunts in Pennsylvania (Reinert, 1990 in Brown, 1993).

The pit and the vertical nature of the pupil are characteristics that can be used to distinguish the Timber Rattlesnake from similarly patterned nonvenomous snakes, such as the eastern fox snake (Elaphe gloydi)(Harding, 1997). The foraging behaviour of Timber Rattlesnakes was studied in detail in Pennsylvania (Reinert et al., 1984). 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). Timber Rattlesnakes prefer areas not frequented by people (Ditmars, 1907; Anderson, 1965), although few such sites still exist (DeGraaf and Rudis, 1983). 1951.

Historical depletion of Timber Rattlesnake colonies in New York State. Conspecific scenttrailing by newborn Timber Rattlesnakes, Crotalus horridus. 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. Minor range extensions have been reported relatively recently in Virginia (Martin et al., 1992), Louisiana (Lutterschmidt, 1992; Dundee, 1994b) and Florida (Jenson et al., 1994). Timber Rattlesnakes have been employed as study subjects to test a number of novel techniques. Look at the eyes. COSEWIC Mandate The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) determines the national status of wild species, subspecies, varieties, and nationally significant populations that are considered to be at risk in Canada.

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. 1960. 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). Copeia 1958: 8386. The colonial nature of Timber Rattlesnakes was a factor contributing to their extirpation from Canada by humans (Plourde et al., 1989). 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). Brown, W.S., L. Jones and R. Stechert. 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. The last state lifted the bounty on Timber Rattlesnakes in 1971. Several varieties of snakes can be found in the area including the more common garter and milk snakes.

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. They have been extirpated from the states of Maine and Rhode Island, and may be close to extirpation in New Hampshire (Brown, 1993). Now go up the Genesee River and the probability of finding a rattlesnake goes up dramatically. 1985. Optimal forest composition and management strategies for Timber Rattlesnake habitat remain a subject of debate because canopy cover is a significant factor in the temperature profile of a den site.

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. There are many ways to contact the Government of Ontario. A family outing at the Niagara Falls State Park turned deadly earlier this week. Copeia 4: 976981. The Ontario Ministry of Natural Resources Committee on the Status of Species at Risk in Ontario (COSSARO) has designated the Timber Rattlesnake an endangered species under the following criteria: any native species that, on the basis of the best available scientific evidence, is at risk of extinction or extirpation throughout all or a significant proportion of its Ontario range if the limiting factors are not reversed (Ibid.). In 1978, COSEWIC designated its first species and produced its first list of Canadian species at risk. I normally would. 2001. 1981. The combat dance of the Timber Rattlesnake. 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). Committee on the Status of Endangered Wildlife in Canada. CW6914/1112002EINISBN 0662318803. Clearly, the potential impacts of human persecution are enormous. and C.H. A population is defined by its den, which is critical to the survival of the entire population (Brown, 1993). 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). Sheds can be measured directly by painting the rattle and then counting unpainted segments upon recapture (Brown, 1991). Assessment based on a new status report. American Zoologist 28(4): 195A. The rattle is the most obvious behavior of these snakes, apparently used when the individual feels angry or threatened. The reptiles of Missouri.

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). Timber Rattlesnakes are seasonally migratory, from den to summer range and back (Brown, 1993). The dynamics of this population suggests a rapid turnover, with newly matured adults comprising a high proportion of the total population. Designations are made on all native species for the following taxonomic groups: mammals, birds, reptiles, amphibians, fish, lepidopterans, molluscs, vascular plants, lichens, and mosses. The facial or loreal pit, which is present between the eye and the nostril on all pit vipers, functions in detecting the body heat of endothermic prey (Schmidt and Davis, 1941). 1958. Cook, F.R. Additionally, some snake hunters claim that Timber Rattlesnakes will not leave the den until they have shed (Ibid.). As there have been no recorded observations of the Timber Rattlesnake in almost 60 years, it is assumed not to exist in Canada. Adults usually vary in length from 0.5 to 2 metres (1.6 to 6.6 feet), but some can grow to 2.5 metres (8.2 feet). Copeia 1998(2): 411422. There are no known populations of the Timber Rattlesnake in Canada and the last sighting was almost sixty years ago. By the early 1970s, the Timber Rattlesnake had been nearly extirpated in all but the most remote sections of the United States (Morris, 1974). 1939. Crotalus horridus (Timber Rattlesnake) longevity. Brown, C.W. 1994. Figure 1. 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. They are called Rattlesnake Islands, and we are told they are so infested with these reptiles that the air is infected with them." 2 Jonathan Carver, on his way from Detroit to Niagara in 1768, elaborated upon the theme and added some quaint embroidery: "There are several islands near the west end . Ohio Conservation Bulletin 15: 14. Brown, W.S. According to . One seemingly harmless, yet potentially significant example of habitat alteration is the repositioning of basking and shelter rocks by people looking for Timber Rattlesnakes (Brown, 1993). Photo by Rob Moore 1969. 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). 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 . Aldridge, R.D. A 5-year-old boy was rescued and his mother died after the two jumped 90 feet into the Niagara Gorge at Niagara Falls State Park on Monday, officials said. The adult snakes are large, ranging from 887-1892 mm (34.92 - 74.49 inches) in total length (Collins and Knight 1980). Conservationist 36: 2729. Rupert, R. Jr. and H.K. Males migrate further than females, likely to search for mates. Contrary to popular belief, rattlesnakes cannot be aged directly by counting the number of segments in the rattle. Brown, pers.

A variety of habitats are traversed throughout the active season, depending partly on individual age and reproductive state. But, for the real treat, skip the bridge and head on. The most distinctive behaviour of rattlesnakes in general is the use of the rattle itself. Because of their gregarious nature, hundreds were sometimes killed in a raid on a single den (Schmidt and Davis, 1941). Additionally, the population genetics of Timber Rattlesnakes have been analyzed using microsatellite markers (Bricker et al., 1996; Villarreal et al., 1996; Bushar et al., 1998). 743 pp. Herpetological Review 25(1): 3334. The site also contains some of the best-exposed fossils you'll find in the entire Niagara Region. In the northern part of their range, they hibernate from September to April (an average of 7.4 months) in communal dens. In Kentucky, we have four venomous snakes: the timber rattlesnake, pygmy rattlesnake (mainly found . Toner. Figure 2. 253 pp. 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. 1919.

They can live up to 25 years, reaching their adult size by about 45 years. The natural lifespan of the Timber Rattlesnake in the northern part of its range is approximately 25 years (Brown, 1993). 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). on wood turtles with Dr. Ron Brooks at the University of Guelph.
