Plump and deep-voiced, the Colorado River toad (Bufo alvarius) is the Orson Welles of amphibians. The largest toad native to the United States exudes a paralyzing, hallucinogenic poison that can kill a dog that bites or mouths it. The “field guides” at this site from eNature are full of fun facts about the Colorado River toad and 4800 other species of North American wildlife. Sponsored by the National Wildlife Federation, eNature peddles all sorts of outdoor products, but the field guides are free. Pithy species profiles cover the taxonomic spectrum, from the American horse fly to the white sturgeon to the saguaro cactus. You can listen to the calls and songs of vocal creatures such as birds and frogs and learn to recognize the tracks of mammals.
