Frogs and Wilsons Snip
Recordist: James Thatcher
Recommended charity: Washington Environmental Council
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.
