Pseudacris regilla

Pacific Chorus Frog (Pseudacris regilla)

Where found: The Pacific Chorus Frog, formerly the Pacific Tree Frog (Hyla regilla) is a species of chorus frog native to the pacific coast of North America from Baja California in Mexico, through the states of California, Oregon, Washington (it is the Washington state frog), and into Canada and extreme southern Alaska. It ranges east into Nevada and Idaho.

Description: This is probably the most commonly heard and encountered frog in California and its call is often heard as a nighttime background sound in Hollywood movies. The Pacific tree frog can reach up to about 5 cm in length. The males are often smaller than the females. These frogs can have highly variable color on their bodies anywhere from gray, brown, tan or bright green and can even change between them. They are usually a pale or white color on their bellies. They have many variations of markings on their back and sides that are usually dark and spotty. The one identifiable mark is a dark stripe that goes over the eye from the nose to the shoulder. Their skin is covered in small bumps. They have long legs compared to their bodies and they tend to be slender. Their toes are long and are only very slightly webbed. On the end of each toe, there is a round sticky pad that is used for climbing and sticking to surfaces.
