I'd never had the pleasure of hearing wood frogs (Rana sylvatica) "live in concert" before but following up on a tip from a friend I was thrilled to find a huge number at a vernal pool at Kickapoo State Park. Temperature was upper 60's though my understanding is that they will breed at much lower temperatures. In the picture of the pond itself all the glowing spots are frog eyes. Although Spring Peepers were also present in large numbers, the males were not calling from in the water itself, so I suspect all the eyes in that shot are wood frogs.

Dang, already? I guess spring has truly sprung in the east, then. I like how they sound a bit like ducks, and how a chorus sounds like 100s of evil nocturnal zombie ducks. Your eye shine pic is awesome.
Also, FYI, you need to hit "Lookup" in the Add Observations form for the species to "stick." I need to figure out a way to make that more obvious.
Thanks for the tip.
