This frog was trying to engage in amplexus with a Bufo punctatus toad. The toad was attempting escape in vain, as the frog was still chasing it after 2 minutes when we left the scene. Further information on the night found in other 5/15/13 observations.
These frogs were found in amplexus at about 10:00pm in a caliche tank (~50 ft long, ~20ft wide) surrounded by grassland. These frogs were distinguished from H. versicolor by their shorter call. An explosive breeding event was occurring due to 2 inches of rain the night before. These frogs formed a chorus, along with B. nebulifer, G. olivacea, and B. punctatus (with separate iNat observations). We saw 40-60 H. versicolor individuals at this tank, with similar sightings at nearby tanks (~.5 mile away). It was about 75° with ~10 mph wind.
I thought it was toad, because we don't have any ponds around my house. But my friend taught me this is cope's gray tree frog.
I thought kind of rare in OH.
Heard dozens of them on our Elementary night frog hunt, saw 3.
After I took these photos, when the weather turned colder, this frog took up residence in our outside phone box... between the phone box and the house and was there for a number of weeks, not sure exactly how long.
Large leks heard on warm, humid summer nights (most nights in TN) in a roadside creek near a private residence.
