Monday, June 18, 2012 Snakes in the Niagara Gorge Who would have thought that the largest snake I ever saw in New York would be in the Niagara Gorge. Journal of the Pennsylvania Academy of Sciences 64: 136144. Timber Rattlesnakes can live 25 or more years in the wild. Figure 2. Here are our top five vantage points to take in the sights of the Niagara Gorge. 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). Crotalus horridus (Timber Rattlesnake). Rattlesnakes are not usually found above 6,000 feet in . From 1996 to 1998, she conducted field work on a variety of taxonomic groups, including marine invertebrates and sea ducks, marine fishes, reptiles, waterfowl and mammals. Fatal bites often involve small children (Guidry, 1953), who are more sensitive to venom due to their smaller size. The last sighting of one of these venomous . The predominant ambush position of this sitandwait predator involves coiling adjacent to a fallen log with the head positioned perpendicular to the long axis of the log. Time: 1 - 2 hours. 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. Herpetological Bulletin of the New York Herpetological Society 17 2324. Contributions of the Royal Ontario Museum Life Sciences 53: 192. 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. Frank Darroch collected the last confirmed Timber Rattlesnake in the Niagara Gorge on August 22, 1941 (Cook, 1999). The cessation of feeding was apparently induced by the development of large offspring. Hiking with Rattlesnakes. decimation of population through hunting, road-kills, persecution because of discrimination against venomous snakes. Crotalus horridus (Timber Rattlesnake) reproductive phenology. Pp. In Galligan and Dunson, 1979 (above). Species designated at meetings of the full committee are added to the list. Herpetological Review 25(2): 70. Greene and J.B. Friedlaender. I normally would. Timber Rattlesnakes generally begin to rattle when approached within 12 m (Barbour, 1950). 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). Stewart, M.M., G.E. It also provides some amazing unobstructed views of the southernmost section of the Niagara Gorge. Rare. The last recorded sighting of a Canadian timber rattlesnake was in 1941, in the Niagara Gorge. and J.L. WGRZ. Spend a few hours out on the rocks testing your strength. The pupil of the eye is always vertically elliptical in the pit vipers, a feature associated with nocturnal habits (Ibid.). Royal Ontario Museum of Zoology, Handbook No. Cover illustration/photo:Timber Rattlesnake -- Illustration by Marisa Bonofiglio, Woodbridge, Ontario. Kim has also written COSEWIC status reports on the queen snake (Regina septemvittata) and the northern ribbon snake (Thamnophis sauritus septentrionalis). Average shedding rate of Timber Rattlesnakes in northern New York was 1.44 sheds per year (Brown, 1988), compared to two sheds per year in Kansas (Fitch, 1985). It is almost a certainty that the Timber Rattlesnake has been extirpated, as demonstrated by the following quotes: 1881 Garnier: rapidly becoming extinct [in Ontario] 1908 Nash: formerly common and generally distributed throughout the province now nearly extinct 1939 Logier: that the early distribution of this snake in Ontario was more extensive seems likely 1982 Weller: may very well have been extirpated in Ontario 1984 Cook: the last specimen taken in Ontario was from Niagara Glen in 1941 1989 Johnson: extirpated from Ontario 1989 Plourde et al. Hike Description . Stahnke. and F.M. Many translocated snakes immediately leave the area in which they are released (Galligan and Dunson, 1979). The Timber Rattlesnake is a sit and wait predator. Journal of Herpetology 16(2): 151161. A snake den in Tintic Mountains, Utah. 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. In addition to bounty hunting, rattlesnakes have also been harvested for their oil (Ibid.) 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. The most distinctive behaviour of rattlesnakes in general is the use of the rattle itself. 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. Located deep in the Niagara Gorge, stairways lead to four kilometres (2.5 miles) of rugged hiking paths that wind through this pristine pocket of Carolinian Forest, past prehistoric geological formations, wild flora and fauna. Female Timber Rattlesnakes may or may not return to hibernation sites to give birth to young (Galligan and Dunson, 1979; DeGraaf and Rudis, 1983). A woman is dead after plunging into the Niagara Gorge with her 5-year-old son Monday in what officials believe was a deliberate act. Mating takes place in late summer (Martin, 1993) and young are born from late August to midSeptember (Galligan and Dunson, 1979). There are more than 24 rattlesnake species and all of them have that most-famous feature: the rattle! 200 pp. Eastern Massasauga Rattlesnake This is the smallest of the three venomous snakes in New York, with an average size of 1 to 3 feet in length. Wildlife Species A species, subspecies, variety, or geographically or genetically distinct population of animal, plant or other organism, other than a bacterium or virus, that is wild by nature and is either native to Canada or has extended its range into Canada without human intervention and has been present in Canada for at least 50 years. Brown, W.S., D.W. Pyle, K.R. A profile and impact assessment of organized rattlesnake hunts in Pennsylvania. The climb up Shortoff Mountain is 1,500 feet in about a mile. An area of approximately 50 km of suitable habitat is required to sustain a population (Brown, 1993).

The climb up Sitting Bear is shorter but harder. Reinert and L. Gelbert. Mountain Lion . 85 pp. Although some authors believe that colour phases are sex related (Ditmars, 1907), others have suggested that the variation is a thermoregulatory adaptation, as black specimens occur with greatest frequency in mountainous regions (Schaeffer, 1969). University of Missouri Press, Columbia, Missouri. Niagara Falls, NY (14301) Today. Typical litter size varies from five to thirteen young, according to geographic location (Edgren, 1948; Anderson, 1965; Galligan and Dunson, 1979; Brown, 1993) and gestation period can vary as much as four to six weeks, depending on weather (Martin, 1996). Cameron, Toronto, Ontario. Harwig, S.H. Since this time, many researchers have conducted searches (including Frank Darroch, E.B.S. Sheds can be measured directly by painting the rattle and then counting unpainted segments upon recapture (Brown, 1991). 1956. Of the populations that remain, many have been reduced to 1520% of their numbers a few decades ago (Martin, 1983). While there are many different types of snakes found at New River Gorge National Park and Preserve, only two types are venemous; the Northern Copperhead and the Timber Rattlesnake. Alan Berner/Seattle Times A relentless sun was beating down as I walked back to my. "Our rescuers, along with Niagara Falls Fire Department, were able to reach pretty quickly both of the victims," the police captain said. Pp. 743 pp. Due to their appearance and frightening actions, people assume snakes to be dangerous (Edward & Foote, 1979). Timber Rattlesnakes can be confused with Massasauga rattlesnakes and some nonvenomous species, such as the fox snake. 1997. . Copeia 1958: 8386. 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). 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). 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). Male snakes mature at a mean age of 4 years, while females mature at a mean age of 6 years, depending on the location of the population. A case in herpetological conservation: notorious poacher convicted of illegal trafficking in Timber Rattlesnakes. Zoos have reportedly been known to attach additional rattles on the end of broken ones to make them appear more impressive (Ditmars, 1907; Schmidt and Davis, 1941). 1974.

Favourite basking rocks are used year after year, and may attract many snakes at one time (Harwig, 1966). Figure 1. Batrachians and reptiles of Ontario. 5. Historical records are widely scattered and anecdotal and do not provide a clear picture of the species former abundance and distribution (Cook, 1999; see also Fig. Transactions of the 4th North American wildlife conference. 1994. Bulletin of the Antivenin Institute of America 3: 4357. Approximately half of a Timber Rattlesnakes daily activity cycle is spent basking, in order to maintain its preferred body temperature (Ibid.). In Galligan and Dunson, 1979 (above). The most recent confirmed records of this rattlesnake in Ontario are from the Niagara Gorge in the 1940s. Jensen, J.B., B.W. 1907. The natural lifespan of the Timber Rattlesnake in the northern part of its range is approximately 25 years (Brown, 1993). 1957. We also coordinate Ontarios actions on climate change in the name of healthier communities, ecological protection and economic prosperity. * Formerly described as Vulnerable from 1990 to 1999, or Rare prior to 1990. Niagara Glen Add to Itinerary. SSAR Herpetological Circular No. Palmer, J.R. Bailey and J.R. Harrison. The colonial nature of Timber Rattlesnakes was a factor contributing to their extirpation from Canada by humans (Plourde et al., 1989).
