Sometimes referred to as the Pacific tree-frog, this frog gave us the “ribbet” in cartoons. There is nothing like the sounds of the pacific chorus frog at night in spring. This however is a single frog separated in a lone pond living quite happily.
This frog is chiefly nocturnal, spending the day beneath logs, rocks, or other debris. During breeding season, males will call to attract females. A number of calling males is known as a chorus. A dominant male, or chorus master, leads off the calling which is then followed by subordinate males. If an intruding male comes instead, the Pacific Tree-frog changes its usual two-part “ribbet” to a one-part encounter call. An observer trying to locate the Pacific Tree-frog can mimic their calls and take over as chorus master, enticing the other frogs to begin calling as well. If this is done, be prepared to take on the responsibilities that come with being the chorus master!
