This male peeper had his colors reversed, I’ve never seen one with light markings on a dark body.

Here’s a video of him making noise!
This one was calling from the edge of the towpath and can be heard calling when the temperatures drop. I hear some calling last year after a 3-4 inch spring snowfall.

 A female Green frog. You can tell the females from males because their eardrums are about the same size as their eyes. The Green frogs started calling several weeks ago during the warmup, and began again last night, but will stop calling with the temperature drop. With the Valley’s water levels being so low, compared to last year, she was probably coming from the adjacent pond to the more permanent deeper lock, where the larger frogs breed. There tadpoles can take up to 2 years to metamorphose, so they need the more permanent water environments.
