Communication and Perception
Pacific treefrogs have a very rapid call that has been described as a “kreck-ek” noise. The rapid call is called the chorus note; this serves to bring individuals in the area together for breeding. Pacific treefrogs also have an encounter call that warns other males not to get too close during mating season. This differs from their normal call, which is lower pitched and longer. Research has shown that males avoid overlapping calls in order to increase each male’s chance to attract a mate. Typically, up to three males can call without overlapping, if timing is well synchronized. Pacific treefrogs have well developed senses of sight, smell, and hearing. Hearing is particularly well-developed, as these frogs must be able to call to each other during mating season.
