Mystery Sounds: unknown owl vocalizations
South Fork Crooked River, Crook County, Oregon
May 4 2012, approximately 1 hour after dusk.

Recorded outside the foot of my tent with AT3032 microphones and a SD702 re=
corder. There are also some rustling and sounds in the vicinity from other =
campers in our group settling in for the night.
Edits:  the recording was amplified approximately 12 dB over natural, sever=
al car doors and one stomach grumble were edited out.

If you have a guess which species might make such sounds, please feel free =
to comment.

My guesses: short-eared owl, long-eared owl, or western screech owl.
