Pacific Chorus Frog, Pseudacris Regilla

Day 213: On March 9, I posted a photo of a grey-brown Pacific Chorus Frog, the little critter almost indistinguishable from the decaying leaves on which it was resting. This image shows a specimen in typical spring/summer coloration. This species is highly variable because Pseudacris regilla has the ability to camouflage itself, although the transformation of its color and markings may take weeks to occur. The alteration is initiated by a response to light rather than to environment, i.e., a long period of cloudy weather would return this frog to the dull browns of winter.
