Timber Rattlesnakes have been employed as study subjects to test a number of novel techniques. 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). 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). Martin, W.H., J.C. Mitchell, and R. Hoggard 1992. Duran. Timber Rattlesnakes are large, oviviviparous, iteroparous, longlived and slow to mature, with a relatively long mean generation time (Brown, 1991).

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). King. 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. The last recorded sighting of a Canadian timber rattlesnake was in 1941, in the Niagara Gorge. Timber Rattlesnakes can live 25 or more years in the wild. Herpetologica 4: 107114. But, for the real treat, skip the bridge and head on. Houghton Mifflin Company, New York.

The most recent confirmed records of this rattlesnake in Ontario are from the Niagara Gorge in the 1940s. Sex ratio in a New Jersey brood was 1:1 (Odum, 1979). Foregoing reproduction in some years is apparently necessary to allow females to gain weight and store yolk protein in the developing eggs (Galligan and Dunson, 1979; Brown, 1981). ), although some public lands may have been managed with the goal of eliminating Timber Rattlesnakes because of fears that their presence might deter visitors (Cook, 1999). Timber Rattlesnakes once occurred throughout the Carolinas and Virginia, but they have been eliminated from areas of extensive deforestation and human settlement (Martof et al., 1980). Thus the proposed status for COSEWIC is extirpated. Crotalus horridus (Timber Rattlesnake) climbing. Batrachians and reptiles of Ontario. 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). 605622. Ottawa. Stewart, M.M., G.E. 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). Brown.

Field observation of the association of adult and neonatal Timber Rattlesnakes, Crotalus horridus, with possible evidence for conspecific trailing. 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. These features include slow maturation rates, low reproductive output, low juvenile survival and slow population replacement rate (Harding, 1997).

Ideal habitats are forested areas with rocky outcroppings, dry ridges and second growth coniferous or deciduous forests (Ibid.). The specific Latin name horridus means dreadful, in reference to the venomous nature of the Timber Rattlesnake (Collins and Knight, 1980). They can live up to 25 years, reaching their adult size by about 45 years. The Timber Rattlesnake is a large venomous rattlesnake, characterized by yellow or brown coloring with dark brown or black Vshaped bands across the back. The most recent confirmed records of this rattlesnake in Ontario are from the Niagara Gorge in the 1940s. Herpetological Review 23(3): 91.

In Ontario, hibernacula were most often located along the Niagara escarpment, following the limestone outcropping northward toward the Manitoulin District (Logier and Toner, 1961). Timber Rattlesnakes often hibernate with copperheads (Agkistrodon spp.) 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).

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). 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).

Logier, Frank Ross, Craig Campbell and James Kamstra), but no Timber Rattlesnakes have been found (Ibid.). The remote areas preferred by Timber Rattlesnakes are becoming increasingly less ideal because of enhanced access to such areas via fourwheeldrive and offroad vehicles (Galligan and Dunson, 1979; Brown, 1993). Designations are made on all native species for the following taxonomic groups: mammals, birds, reptiles, amphibians, fish, lepidopterans, molluscs, vascular plants, lichens, and mosses.

Herpetological Review 25(1): 28. Herpetologica 12: 326. 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. Ovulation occurs from late May to early June, while maximum spermatogenesis is reached in July, continuing through September (Aldridge and Brown, 1995; Martin, 1993).
