Yosemite Photos, Video and News

From my post on:

I had been hearing this weird screeching noise in the meadow at night. After a little research I believe it is the call of the Barn Owl as the sound from this video is exactly what it sounded like. Very eerie.

I looked around and could not find any info about Barn Owls in Yosemite Valley. Do they live there?
