It’s That Time Of Year Again…

June 14th, 2016. The breeding season for Cope’s Gray Treefrogs (Hyla chrysoscelis) has arrived again. These frogs like to breed in small pools of water and will use watergarden containers, of which we have several near the house. 

As the breeding season approaches, we’ll often hear soft, chirping calls as they settle in near the containers. This year was no exception and prompted us to check the window frames on the front of the house where we’ll often find one or two encamped.

This young frog – judging by its size – was hunting insects on the side of a window frame.

I caught it and it managed to wiggle free. I was, however, able to hold it so that I could photograph the…

bright yellow color on the inside of its thigh. This color serves as a key characteristic for distinguishing a Cope’s Gray Treefrog from a Bird-voice Treefrog (Hyla avivoca) in areas where both species are endemic.

Although the frog was desperate to wriggle free from my grasp, once free, it was quite content to…

sit on my hand and pose for photos from several angles. Perhaps it was enjoying the warmth of my hand because it was reluctant to…

return to the window frame.

Sure enough, within a couple of days the frogs began their raucous mating calls and eggs are visible in some of the water containers.
