| Scenes from a Foothill Yellow-legged Frog breeding site along a river in Oregon, including air and underwater calls. (The underwater calls were not recorded along with the video, they were added later, however, the frogs depicted underwater are male frogs who had been calling.) | A Foothill Yellow-legged frog calls at the edge of a small pool in a river with just its head out of the water, producing a call that can be heard in the air and underwater. The sounds heard here were recorded with an underwater microphone placed about 3 feet behind the frog. | |
