The Unbearable Cuteness of Tree Frogs
This is either a Common Gray Treefrog or a Cope’s Gray Treefrog. Even though they have gray in their name, they can be brown or green or blotchy. One characteristic that helps identify them is that there is a bright orange area on the underside of their thighs. The two species look exactly the same, except the Cope’s has half the number of chromosomes as the Common Gray, and it trills faster (from National Audubon Society Field Guide to Reptiles and Amphibians). I haven’t heard them trill, so I can’t tell. I never saw them before, but this year I have seen them almost every night.
