The California tree frog or California chorus frog (Pseudacris cadaverina) is a "true" tree frog (family Hylidae) from southern California (USA) and Baja California (Mexico).[2] Until recently, the California tree frog was classified in the genus Hyla.[2][3]


It is a cryptically colored species of tree frog, often resembling granitic stones. It is grey or light brown on its dorsum with darker blotches, and has a whitish venter. It is yellow on the undersides of its legs, groin, and lower abdomen; males of the species have a dusky-yellow throat. The California tree frog has conspicuous toe webbing and pads, and its dorsal skin is roughened and warty. It is 2.9–5 cm (1.1–2.0 in) long.[3][4]

Habitat and conservation[edit]

This species is most likely to occur along streams with abundant boulders and cobbles in their channels. Its distribution is spotty and localized. These frogs are easily handled.[4]

California tree frog is not considered threatened by IUCN: it is a relatively common species with broad distribution, and there are no major threats, except perhaps UV radiation that reduces embryonic survival.[1]
