Species Spotlight: The Gray Treefrog Complex

The "Gray Treefrog Complex" consists of the Common Gray Tree Frog (Hyla versicolor) and the Cope's Tree Frog (Hyla chrysoscelis). These two species are basically only distinguishable by their calls and number of chromosomes, meaning they're extremely difficult to identify by a photo alone. Both frogs have gray-green, almost lichen-like skin that gives them excellent camouflage. Their exterior is warty like a toad, and they have the sticky toe pads distinctive of tree frogs. When it comes to telling them apart, it's easier done by sound than by sight. Listen to both calls, and then let us know which one you've heard at TNI!
