Wildlife Spotting

Ashley is correct. It is a newly metamorphosed grey treefrog. They are green when they first emerge from the water. It is not a green treefrog.

This is definitely not a Green Tree Frog, it doesn't have any of the characteristics of one. And Guy Bird's suggestion is also not correct. Like I said in my earlier comment, they is no way to tell them apart by a picture, and both are in range, so you cannot call it either one of the species definitively. You can only say it is one or the other.

It's a little out of it's mapped range, but this looks like a green treefrog - Hyla cinerea. Check it out at http://www.npwrc.usgs.gov/resource/herps/amphibid/species/hcinerea.htm

These two species are visually indistinguishable and are both in range, so at this point you cannot tell which species it is.

Nice spotting!
