The Pacific Tree Frog is one of our smallest but loudest amphibians of the Pacific Northwest. Pacific Tree Frogs live from southern B.C. south to California and east to Montana and Nevada. Its color varies from almost a bronze brown to a light lime green.
Individuals can change color in green and brown tones in a few minutes.
This color change is related to the temperature and amount of moisture in the air, not the background color as in most other amphibians and reptiles. This color change gives it the protection of camouflage as it hops and crawls about on low leaves, branches and on the ground in open forests and forest edges looking for flying and crawling insects to eat. This is an adaptable species who can live in coastal rainforests as well as ponds near treed areas of the interior dry belt. Male tree frogs are smaller than females and have a dark throat patch, created by the stretching of the skin while vocalizing. Male frogs are territorial and protect their part of the pond from other males by repeating their two-toned mating call at night.
