Gray Treefrog Species Complex

The Gray Treefrog Species Complex is a fascinating duo of practically indistinguishable amphibians: the Eastern Gray Treefrog (Dryophytes versicolor) and Cope's Gray Treefrog (Dryophytes chrysoscelis). These small, arboreal acrobats are renowned for their remarkable ability to change color, shifting from mottled gray to striking shades of green or brown to perfectly match their surroundings. This incredible camouflage makes them masters of disguise among the tree bark and lichen of their woodland homes. What truly sets this complex apart is a hidden genetic secret. While they look identical to the naked eye, the Eastern Gray Treefrog has twice the number of chromosomes as its sibling species. The easiest way to tell them apart in the wild is by listening to their trilling calls during the spring breeding season. Found clinging to branches, resting on leaves, or hanging around porch lights, these adaptable frogs are a beloved, vocal staple of eastern North American forests.

Hábitat: Found predominantly in deciduous forests, woodlands, and suburban areas, typically living high up in the canopy but descending to shallow, fishless wetlands and ephemeral pools to breed.
