National Museum of Natural Sciences, National Museums of Canada, Ottawa, Ontario. The western diamondback rattlesnake ( Crotalus atrox) is one of the best-known venomous snakes in North America. Copeia 1960: 336337. Of the populations that remain, many have been reduced to 1520% of their numbers a few decades ago (Martin, 1983). Striped mutations and amelanistic partial albinos have also been recorded (Hudson and Carl, 1985; Dundee, 1994a). Alfred A. Knopf, New York. Authorities have recovered the mother's body . It was an old specimen measuring 56 inches in length as this one was such an old specimen and as no others have been taken there in recent years, Mr. Patch was of the opinion that it was the last of its race. Villarreal, X., J. Bricker, H.K. The most recent confirmed records of this rattlesnake in Ontario are from the Niagara Gorge in the 1940s. They are very loyal to their den site and will return year after year. Copeia 4: 976981. 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). Fatal bites often involve small children (Guidry, 1953), who are more sensitive to venom due to their smaller size. You won't find any rattlesnakes in Alaska, Delaware, Hawaii, Maine, and Rhode Island. Identifying a Gopher snake starts by approaching it with caution.

Pit vipers are venomous snakes that have heat-sensing pits on the sides of their face that help them detect prey. Herpetologica 25: 6566. Matthews. 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). Crotalus horridus (Timber Rattlesnake) coloration. 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.

In Ontario, the Natural Heritage Information Center determined that the Timber Rattlesnake is extirpated, the chance of rediscovery being very small. 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). 1988b. Brown, W.S. These features include slow maturation rates, low reproductive output, low juvenile survival and slow population replacement rate (Harding, 1997). First, they responded to the lower Niagara River gorge, near Devil's Hole, after a young man slipped into the fast rushing water there. I've heard that there have been reports of people seeing or hearing rattlesnakes at the G12 area, so I found this article about the snake and what to do. 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. 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). 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.). Although some of the snakes in this region are very common, many of these snakes are endangered and at risk. Timber Rattlesnakes prefer areas not frequented by people (Ditmars, 1907; Anderson, 1965), although few such sites still exist (DeGraaf and Rudis, 1983). The Timber Rattlesnake receives varying degrees of protection throughout its range in the United States.

Taken together, these factors result in a small number of new individuals added to the population each year. 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). The Timber Rattlesnake has already been designated as extirpated in Ontario by the Nature Conservancy (Oldham, 1997), and the vast majority of experts agree that the Timber Rattlesnake no longer exists in Canada. Edgren, R.A. Jr. 1948. 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). Conspecific scenttrailing by newborn Timber Rattlesnakes, Crotalus horridus. 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.). and C.H. The last sighting of one of these venomous . 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. COSEWIC status reports are working documents used in assigning the status of wildlife species suspected of being at risk. Dundee, H.A. Moler 1994. This is true for two reasons; first, a segment is added each time a snake sheds (not necessarily once a year) and second, segments are continually being broken off most wildcaught individuals have between five and nine segments in their rattles (Schmidt and Davis, 1941). Harding, J.H. It's fairly rare to see a rattlesnake along the PCT in Oregon, but it does happen. In Galligan and Dunson, 1979 (above).

Favourite basking rocks are used year after year, and may attract many snakes at one time (Harwig, 1966). Reinert, H.K. 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 snake feeds on rodents and other small mammals. Here are our top five vantage points to take in the sights of the Niagara Gorge.

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). COSEWIC HistoryThe Committee on the Status of Endangered Wildlife in Canada (COSEWIC) was created in 1977 as a result of a recommendation at the Federal-Provincial Wildlife Conference held in 1976. The winter habitat is primarily the den, which is located on a south facing rocky outcrop. 1908. Neill, W.T. Hudson, R. and G. Carl. 2001. Foraging success and the ability of females to regain mass may be the main determinant of the length between successive reproductive events (Brown, 1991). However, in light of its rangewide decline, the U.S. 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. 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).

Ironically, the food habits of the Timber Rattlesnake make it an economically valuable species which, were it not for its venomous nature, might actually have been encouraged to set up residence in Ontario (Logier, 1939; Martof et al., 1980). 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). It's common for rattlesnakes to be mistaken for gopher snakes, so you need to be able to tell them apart. Time: 1 - 2 hours.

However, the rush of over 6 million cubic feet of water per minute, approaching the cascade at about 25 miles per hour, and plunging 70 to 190 feet across a distance of about 3000 feet, make it one of the natural wonders of the world. 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. The Timber Rattlesnake is a heliothermic species, with the ability to regulate its temperature by radiation absorption throughout its daytime activities (Odum, 1979). 1984.

Ontario Herpetofaunal Summary. 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. Logier, E.B.S. Reinert, H.K., D. Cundall and L. Bushar. The Midget Faded Rattlesnake is only found in the Flaming Gorge area, but it's worth noting because it is far more deadly than most other rattlesnakes. 1981. 365 pp. The most important habitat component of northern Timber Rattlesnakes is the communal den within which hibernation takes place. Follow the service road 0.2 mile, and turn right onto US 62/Niagara Falls Blvd. Population declines have also been noted throughout the Timber Rattlesnakes range in the United States, particularly in New York, Pennsylvania, Virginia, Connecticut and New Jersey (Brown, 1981, 1993; Reinert, 1990). Anderson, P. 1965. Unpublished Timber Rattlesnake account in The Natural History of Amphibians and Reptiles in Canada. Timber Rattlesnakes can live 25 or more years in the wild.
