Imagem de Anaxyrus boreas (Baird & Girard 1852)

Descrição:

Adult males examined with grayish belly and obvious webbed feet. Two dozen male toads observed in calm bank water. Toads congregated in relatively small section of lake and were evenly spaced apart. Male toads contacted by another toad would sound by chirping, apparently announcing to the aggressing toad that he is engaging another male.
