Fish and Wildlife Service is conducting a review of the Timber Rattlesnake for possible protection under the federal Endangered Species Act (Casper and Hay, 2001). Timber Rattlesnakes are large, oviviviparous, iteroparous, longlived and slow to mature, with a relatively long mean generation time (Brown, 1991). DeGraaf, R.M. Sex independent ground colour in the Timber Rattlesnake, Crotalus horridus horridus. 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. .

The Timber Rattlesnake is a large venomous rattlesnake, characterized by yellow or brown coloring with dark brown or black Vshaped bands across the back. 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). 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). Thompson. to Brown, 1993). Journal of Herpetology 6: 234237. Symptoms of Timber Rattlesnake poisoning include swelling, pain, respiratory difficulty, weakness, giddiness, haemorrhage, weak pulse or heart failure, nausea, vomiting, ecchymosis, heart pain, gastric disturbance, paralysis and unconsciousness or stupor (Hutchinson, 1929).

In Ontario, hibernacula were most often located along the Niagara escarpment, following the limestone outcropping northward toward the Manitoulin District (Logier and Toner, 1961). 2001. Timber Rattlesnakes can live 25 or more years in the wild. They are very loyal to their den site and will return year after year.

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. Hibernation in the northern parts of the Timber Rattlesnakes range occurs in the cracks of rocky ledges, usually facing south (Odum, 1979). The Timber Rattlesnake was among the first snakes to be officially designated as an endangered species under Ontarios Endangered Species Act, 1973 (Weller, 1982). As officers frantically searched for the man, they. The species has not been sighted in Canada in almost 60 years. Behler, J.L.

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 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. 1 and 2. These demographic characteristics also make the Timber Rattlesnake a species in which there is little natural harvestable surplus of adult individuals (Brown, 1993). How to comment on protecting species at risk, How to get an Endangered Species Act permit or authorization. In Ontario, the Timber Rattlesnake has been assigned a rank of SX by the Natural Heritage Information Centre as apparently extirpated from Ontario (Oldham, 1997). Uhler, F.M., C. Cottam and T.E.

Genetic variation and gene flow within and between local populations of the Timber Rattlesnake, Crotalus horridus. 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. Odum, R.A. 1979. Michelle Starin The trail is oftentimes said to be less than spectacular. Several biological traits of the Timber Rattlesnake greatly reduce its ability to recover from largescale losses of adults in a population. . Spend a few hours out on the rocks testing your strength.

Knight. 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. However, the species has been extirpated from many states, including Louisiana, and it is a candidate for the US Fish and Wildlife Service's Endangered Species List. ** Formerly described as Not In Any Category, or No Designation Required.*** Formerly described as Indeterminate from 1994 to 1999 or ISIBD (insufficient scientific information on which to base a designation) prior to 1994. Clearing of land, killing by humans and commercial exploitation have all contributed to the decline of the Timber Rattlesnake throughout its range (Weller, 1982; DeGraaf and Rudis, 1983). Populations of Timber Rattlesnakes are limited in the northern parts of their range by a small number of suitable nest sites. Colour phases of newborns are readily distinguished after the first molt (Ibid.). Canadian Association of Herpetologists Bulletin 11(2): 39. 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. Bushar, H.K. In Kentucky, we have four venomous snakes: the timber rattlesnake, pygmy rattlesnake (mainly found . 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). However, carrion, reptiles, amphibians, birds and their eggs are also eaten (Uhler et al., 1939; Myers, 1956; Anderson, 1965; Keenlyne, 1972). This weight loss represents 41% of female body weight (Galligan and Dunson, 1979). See Figure 1 for the North American range. State Park Police said their dispatchers received "multiple calls", at about 12:30 p.m., reporting that an "adult female and her child fell into the Niagara Gorge between Terrapin Point and the Cave of the Winds." 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. Authorities have recovered the mother's body . In summer, the preferred habitat for males and nonpregnant females is a wellcanopied forest with thick vegetation, whereas pregnant females prefer a more open forest with many fallen logs and a warmer climate. Be prepared for a chilly breeze, whirlpool rapids, and watching gallons of water rushing to the trough. 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). 1983.

SARA establishes COSEWIC as an advisory body ensuring that species will continue to be assessed under a rigorous and independent scientific process. This ability could be crucial to the survival of newborns through their first winter, as they may be born a considerable distance away from any suitable hibernaculum (Reinert and Zappalorti, 1988a). Rattlesnakes are a member of this family. Kim has also written COSEWIC status reports on the queen snake (Regina septemvittata) and the northern ribbon snake (Thamnophis sauritus septentrionalis). The specific Latin name horridus means dreadful, in reference to the venomous nature of the Timber Rattlesnake (Collins and Knight, 1980). The site also contains some of the best-exposed fossils you'll find in the entire Niagara Region. Timber Rattlesnakes prefer areas not frequented by people (Ditmars, 1907; Anderson, 1965), although few such sites still exist (DeGraaf and Rudis, 1983). An eastern chipmunk (Tamias striatus), a cottontail rabbit (Sylvilagus floridanus) and an unidentified bird were also taken, each representing 5% of total prey consumed in the above study.

Fatal bites often involve small children (Guidry, 1953), who are more sensitive to venom due to their smaller size. Habitat: They are found in field areas, wetlands and edges of moist forests. Wright, A.H. and A.A. Wright. In Ontario, the Natural Heritage Information Center determined that the Timber Rattlesnake is extirpated, the chance of rediscovery being very small. Brown, W.S. Fitch, H.S. From easy to challenging trails - including steep stairways and a little boulder hopping, hiking is recommended between April and mid-November. 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). Royal Ontario Museum of Zoology, Handbook No. Brown, W.S., D.W. Pyle, K.R. human destruction of nesting habitat through direct action, mining, logging, drilling gas wells. The now extinct Timber Rattlesnakes were once common to the area, and where much feared by locals. Spring emergence is likely affected, but not completely determined, by temperature (Galligan and Dunson, 1979). Klauber, L.M. Dundee, H.A. Neill, W.T. The practice of paying bounties on Timber Rattlesnakes in New York ended in 1971 under the Fish and Wildlife Law (Brown, 1981). Stechert, R. 1982.

Males and nongravid females utilize forest habitat with greater than 50% canopy closure, thick surface vegetation and few fallen logs (Reinert and Zappalorti, 1988b). and J.L. The reptile book. 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 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).

Mean body temperature during this time was 26.9C (Ibid.). 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). An area of approximately 50 km of suitable habitat is required to sustain a population (Brown, 1993). Threatened (T) A wildlife species likely to become endangered if limiting factors are not reversed.

During courtship, the male repeatedly strokes the neck region of the female with his chin (Anderson, 1965). 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. Timber Rattlesnakes are seasonally migratory, from den to summer range and back (Brown, 1993). 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). A Louisiana Timber Rattlesnake lived 36 years, 7 months and 27 days in captivity, reaching a total length of 1770 mm (Cavanaugh, 1994). The most distinctive behaviour of rattlesnakes in general is the use of the rattle itself. Identifying a Gopher snake starts by approaching it with caution. Stewart, M.M., G.E. L.K. Others doubt the negative impacts of increased shading, and believe that selective tree removal as a management strategy may actually do more harm than good (Reinert, pers. Moler 1994. Female Timber Rattlesnakes may or may not return to hibernation sites to give birth to young (Galligan and Dunson, 1979; DeGraaf and Rudis, 1983). Penalties can range as high as a $5,000 fine and/or imprisonment for 180 days, in addition to a restitution payment of $2,000 per animal killed (Ibid.). An upstate police department is warning locals to "beware of rattlesnakes" after it received two separate calls over the weekend regarding sightings of venomous timber rattlers. The Birds on the Niagara celebration opens on Friday, February 14 th with a bird tour of the Outer Harbor, followed by Birds and Brew at the Flying Bison Brewery, 840 Seneca Street, from 6:00 . Notes on the herpetology of Point Pelee, Ontario. 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). Introduction to Canadian Amphibians and Reptiles. Field observation of the association of adult and neonatal Timber Rattlesnakes, Crotalus horridus, with possible evidence for conspecific trailing.

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. 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). During hibernation in the same population, mean body temperatures from September through May ranged from 4.3C to 15.7C, with a mean value of 10.5C (Brown, 1982).

During follicle development, females either ate more, or were more efficient at converting food to stored visceral fat. Niagara Fishing ; Fishing Forum ; Rattlesnake Article Mountain Lion . 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). Taken together, these factors result in a small number of new individuals added to the population each year. 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. 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.). Timber Rattlesnake Distribution Map - NYS Dept. 168 pp. Figure 2. Very few snakes can truly be called poisonous, which means the animal releases toxins once eaten.

Harwig, S.H. . 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. Bushar, L.M., H.K. Extinct (X) A wildlife species that no longer exists. 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). Copeia 1948: 132. 5. 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).

Reproduction, growth, and sexual dimorphism in the canebrake rattlesnake (Crotalus horridus atricaudatus). 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).
