Cope's gray treefrog

Well that's why I also added that the Gray/Cope's Gray has the white patch just below the eye which is diagnostic, and that's what this guy has. That is really good that they are breeding in your area well though :)

Hi Ashley, we only have Cope's Gray Treefrogs at Huntley Meadows. But they have literally just begun breeding this year - the first eggs were found last week - so I didn't think that this could be a young Cope's. Also, recent green treefrog metamorphs may lack a distinctive white stripe and yellow flecks (not even all adult green treefrogs have yellow flecks), so that's not particularly diagnostic. I didn't really pay attention to the legs though - which are diagnostic in metamorphs and are striped in the Cope's gray/gray and not in the green. So I will be changing the spotting based on that. Maybe some eggs were laid during the unexpected warm patch we had earlier this year when both species began calling earlier than has previously been recorded.

There are no ways to externally tell Gray and Cope's Gray Tree Frogs apart so I gave the suggestion as it could be either species.
This is not a Green Tree Frog due to the lack of white stripe down the side and lack of yellow flecks on the back. Also, there is a white spot below the eye which is diagnostic for the Gray/Cope's Gray treefrogs which vary widely from gray to green in color.
