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.
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.
