How to identify it
Small treefrog, 19-50 mm snout-vent length, with small toe pads. [1][2]
Dorsal colour varies (green, reddish, tan, gray, brown or black) but typically green or brown; usually a dark eye stripe that rarely extends beyond the shoulder. [1][2]
Versus the California treefrog: dark eye stripe more often present, green more common, toe pads smaller and less conspicuous. [1][2]
Call is a loud two-part 'kreck-ek'; shorter, lower and less musical than the California treefrog's call. [1][2]
No distinct morphological criteria separate it from the Pacific treefrog. [1][2]
Compared with the california treefrog: Larger toe pads and usually no dark eye stripe. [1][2]
Compared with the pacific treefrog: Not separable by morphology; range and genetics are used. [1][2]
