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!
