Description

Habitat

Typically found at an altitude of 0 to 2,110 meters (0 to 6,923 feet).[1]

Ecology: It inhabits a wide variety of habitats , ranging from forests to prairies, wherever there is sufficient moisture and food. It hides under objects or burrows underground when inactive . In New York, distribution is apparently influenced by soil pH (Wyman 1988). It breeds in nearly any slow or standing body of water , including both permanent and temporary pools , generally in sites with few if any fishes (e.g. , Holomuzki 1995). Eggs are laid and larvae develop in shallow areas. Embryo survival declines greatly at pH below 4.5 (J. Herpetol. 26:70). In northern Minnesota, successful reproduction in acidic bog water either does not occur or is a rare event (Karns 1992).[2]

Similar Species

Common in the piedmont and mountain regions of NC, this species is very similar to Fowler's Toad. American Toads are distinguished from Fowler's Toads by a couple of ways: 1. Generally, Americans have only one or two large warts in the big black blotches on the back, whereas Fowler's have 3 or more. 2. In Americans, the parotoid gland (long oval bump behind the eye) does not touch or just barely touches the ridge behind the eye, sometimes connected by a spur. (In Fowler's they touch for a significant length.) Even after looking at these characters, they can be an ID challenge!
