I have a question: a small frog (the body and head are about four inches long), pale grey-brown in color with a whitish stripe down his back, has been sitting in the thin upper leaves of a low tree in our garden for two days. He's clinging to leaves and branches, barely moving, just shifting position now and then, now sitting upright and now hanging upside down. We've never seen anything like this before in the garden, and wonder if he (or she) should be left alone, whether he's sick or just looking for food, or such. I showered him with a fine rain of water from a hose and he lifted up his head and licked up the water so I know he's alive, he looked avid for the water. Any advice would be much appreciated. I don't want to try rescuing the frog if it doesn't need to be rescued but it seems so out of place. I should say that we're in upstate NY.
