Re: Saw-whet Owl?
Phil and all,
Not ruling saw-whet owl out but Birds of North America Online says calling speed is “about 2 per second.” I can vouch that an agitated saw-whet will briefly produce notes even faster. I think a speed nearing a second apart would be more in the Merriam’s Chipmunk range.
