I recorded this pair of barred owls caterwauling tonight with my digital camera from the deck of Mr. Neil's writing gazebo. It's only about 25 seconds long. It's dark so you can't see the owls, but you sure can hear them!
It was my fault. I had suspected there was one barred owl hanging out behind the gazebo, so, I played the "Barred Owl Female Solicitation Call" from Cornell's Voices of North American Owls on my iPod...powerful stuff.
