For your listening pleasure. Frog song in Western Washington. This was recorded at my parents' house which is in the midst of wetlands. I went out to the front porch to record. There's nothing to see in the video - the lights that appear briefly are a neighboring house.
I love the frogs and listening to them sing is one of the things I miss living on the boat. No frogs on salt water, alas. So every spring, I go spend a night at my folks' place. Just to get my hit.
