The two species of Gray Treefrog (Hyla chrysoscelis and H. versicolor) can be told apart by voice, but not by sight.

This silent individual, photographed in Nags Head Woods, Dare Co., NC, 24 March 2002, is identified as Cope's Gray Treefrog (Hyla chrysoscelis) by the range map. H. versicolor occurs only in the mountains.

See Josh Rose's site for another photo of this individual. It's almost as big as the last digit of a thumb!

Waiting patiently under a porch light for a moth to fly into his gape (which happened shortly after I took this photo)!

This frog was actually facing upwards. The brown patch is a piece of plant debris.

A bumpy lump of treefrog tucked in on a railing near my apartment. They are quite tame and generally will not move if you gently touch them.

It's hard to beat a treefrog for cuteness!
