The Timber Rattlesnake is a heliothermic species, with the ability to regulate its temperature by radiation absorption throughout its daytime activities (Odum, 1979). It arose from the need for a single, official, scientifically sound, national listing of wildlife species at risk. Natural Heritage Information Centre, Ontario Ministry of Natural Resources (updated 15012001). The snake uses the rattle to warn potential aggressors to back off or to distract prey. 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.).
