Cope's Gray Tree frog hanging on to a leaf

How to Identify:

1 1/4 - 2 in. (3.2-5.1 cm); green to gray to brown; light spot beneath eye; bright yellow or orange on concealed surfaces of hind legs; large toe pads.
Note: There aren't many differences between this and the gray treefrog. Cope's tends to be smaller, has smoother skin, and when calling, is totally green without dark markings on its back. Their calls, however, are distinct.


Trees or shrubs growing in or near water.


May through mid-July.


A short, loud trill lasting up to 30 seconds; faster and harsher than the gray treefrog. A nasally "wa-a-a-a-a."
