qiao1's Identifications

Either a Cope's gray treefrog (Hyla chrysoscelis), eastern gray treefrog (Hyla versicolor), or pine woods treefrog (Hyla femoralis). It was sitting on its toe pads and I couldn't look at inner thigh color either, so ID probably not possible. The Cope's is known to be at this location, though one publication said it was unlikely to still be there (salt water encroachment).

I think Cope's more likely because it was really hot and dry out (and they can tolerate that more, I gather) and because this frog looks tiny relative to pics of H. versicolor I've seen. The H. versicolor is tetraploid and thus on larger size (I think ... because polyploids have larger cells usually).
