Adult male Cope's Gray Treefrog (Hyla chrysoscelis) calling at night adjacent to a puddle, Johnson County, Iowa
I'm familiar with the calls of our gray treefrog species, and I tracked this chrysoscelis to its location by following its call.
With Heidi Eaton, so some overlap in observations.
About 8-10 inches in length
Encouraged this guy to get across the road before someone ran him over
Mixed hardwood woodland. Under small piece of bark on top of leaf litter.
