Camo Chorus

Day 166: Yesterday, I mentioned the variation of colour one might expect to see in specimens of Pseudacris regilla (aka Pacific Chorus Frog, Pacific Treefrog). Here is an example. Identifiable by the shape of the head/snout and facial markings, this little feller must have emerged from the mud only recently. Its skin has not had time to adapt to exposure to sunlight. If you look closely, you can see where a few patches of bright green are beginning to appear on its side just above the arch of the thigh. Whether an instinctive response prompted this specimen to perch on brown wood as opposed to my previous example's settling on green moss is speculative at best, but is an interesting thought to entertain.
