I have attached a recording of an unusual owl I heard at the McLellan Conservation Area in Spokane County, Washington State, USA. The Cornell Bioacoustic online analysis tool gives a 100% probability that it is a Spotted Owl, which would be, I believe, unprecedented so far east of the Cascade mountains. It gives a 50% probability that it is a Flammulated Owl, which is rare in the area but other records exist. I would like feedback on the recording, either comments about the ID or referrals to owl experts I can contact. Thank you.
