Guess the Nature Geek Photo of the Week!

Cope's Gray Tree Frog, MHSP Pike Marsh b

 This adorable little frog was spotted inside a brochure box at the Pike Marsh picnic area. (Yes, this photo is upright, as the frog is clinging to the side of the box.) Here's a fun fact about it: an individual frog of this species can be gray, brown, green, pearl-gray or nearly white depending partly on changes in its activities or the surrounding environment.
