Pacific Chorus Frogs

Pseudacris regilla

Pacific Chorus Frogs are native to the western United States, from as far north as British Columbia, and as far south as Baja California. Only growing to about 2 inches, Chorus Frogs are often heard more often than they are seen. Across this range, they serenade their habitats with a chorus of “rib-its”, being the only frogs to make the well known sound!

These frogs are also known for their color variation, as they can appear both green and brown with dark splotches across the backs. Pacific Chorus Frogs can quickly switch back and forth from light to dark based on brightness! It takes weeks for them to change fully, but this adaptation allows them to better camouflage when hiding from predators.

When they are fully grown, the frogs are tiny carnivores that eat a variety of invertebrates, including spiders, beetles, flies, and ants. As larvae, they are herbivores, and the switch in food is one of the final components of their metamorphosis.

Pacific Chorus Frogs are excellent climbers due to their circular toe pads that adhere to smooth surfaces, but actually spend lots low to the ground and in bushes. They lay their eggs in still bodies of water and stay near water while terrestrial.

Lindsay is home to a colony of Pacific Chorus Frogs, most of which were brought from a nearby wildlife facility when they closed. They can be seen in our exhibit hall as well as on daily programs!
