Gray tree frog

Description:

It is sometimes referred to as the Eastern Gray Treefrog, Common Gray Treefrog, or Tetraploid Gray Treefrog to distinguish it from its more southern genetically disparate cousin, the Cope's Gray Treefrog (Hyla chrysoscelis). It may sometimes be referred to as the North American Tree Frog by Europeans to distinguish it from their European Tree Frog (Hyla arborea).

Habitat:

The grey tree frog is most common in forested areas, as it is highly arboreal. Their calls are often heard in rural residential areas of the east coast.

Notes:

I think maybe some type of tree frog? It was on the seat of our swingset.
