An endangered California Red-legged Frog which I almost stepped on while birding today. First time I've been able to confirm one, but I've likely seen them before. With this I only have 2 more amphibians to see in the county.
Hard to tell since we only have part of one song in the recording but seems to be the right cadence and tone for Spotted Owl, they're pretty common in Samuel P. Taylor as well.
