American robin
The main predators of the Cascades frogs are the raccoon, mink coyote, water bugs (Belostomatidae), garter snakes ("Thamnophis sirtalis"), and several bird species, such as the sharp shinned hawks, owls, Canada jays, and American robin. The long-toed salamander and adult "R. cascadae" frogs are predators to the eggs and tadpoles, as well.
