Northern red-legged frogs (Rana aurora) are an amphibian species in the true frog family. They have greenish- to reddish-brown skin, red hind legs, dark spots across their backs, and dark facial masks. As a member of the genus Rana, this species is considered a true frog, with characteristic smooth skin and a narrow waist. These frogs are distributed along the Pacific coast of the United States and Canada, from Northern California to southwest British Columbia. There is some range overlap with the federally protected California red-legged frog. Northern red-legged frogs generally breed from January to March, laying eggs in water with submerged vegetation.
