Frogs and Wilsons Snip
To me these sound like Pacific Chorus Frogs, and from what I’ve been able to research this is one of the species found in Colville National Forest. I am more confident however in ID’ing the winnowing of Wilson Snipe in this recording. At the time I recorded it I was unaware of this behavior, or that snipe are to be found in the area. This sound eerily swirls around and moves around in the stereo field in such a way that it was a little unsettling when I didn’t know what it was.
