 Sonoran green toad

Similar to Green Toad but vividly marked above with network of black or brownish that sets off oval areas of greenish yellow ground color. These oval areas are about twice the size of those on Green Toad of similar size. Nocturnal. Voice: A combined high-pitched buzz and whistle, a wheezy call usually lasting 1 - 4 seconds, gradually lowering in pitch or remaining constant and ending abruptly. May be highly ventriloquial, , sounding as if 20 ft. (6m) away when within 5 ft (1.5 m). Voice resembles the Great Plains Narrow-mouthed Toad’s.
