Great advice, friendly people, and lots of frogs!
Eastern Gray Treefrog, Hyla versicolor Female
my gray tree hasnt sang or changed colors...
Well only males sing and they don't do it much if there's only one of them. As for changing colours it really depends what they're sitting on. This one goes from nearly black to white, though she never gets green. The boys who live with her mostly range between brown and green.
