I love that last pic. He looks so expressive! I think you should give him a little kiss.
I think we have a record number of Cope's Gray tree frogs this year. The other night I heard 5 or 6 starting to converge on my swamp pond. I had procrastinated enough, so I got out there and cleaned it out. Then a cold front came through, the temps dropped 40 degrees, and the frogs disappeared!
