Pacific Treefrogs, or Pacific Chorus Frogs, abound around our house and the whole Pacific Northwest. We hear them calling from our pond, find them in the bushes sunning themselves (a bit of a surprise to find frogs sunning) and find newly metamorphosed frogs in the lawn.
Pacific Treefrogs vary in color, and can change the darkness of their skin color in a few minutes.
You can recognize a Pacific Treefrog by the black stripe through the eye and the rounded toe pads (image 6).
The genus and species names of this frog have changed, and remain somewhat controversial. See Wikipedia
