for somebody. What kind of owl (I assume it is an
owl) would be flying around in the middle of the night, over typical
Seattle-urban 'East Side' wooded hillsides uttering short screeches (~1 sec)
at ~10-12 second intervals? Barn, great horned, screech, or something else?
This is the Eastgate area.

It sounds like a barn, though short and a little less raspy; a little soft
for great horned though similar to those noises young birds make; and not
sure what a screech might make in flight. There are great horned and screech
around the neighborhood sometimes, though haven't heard them hooting/tooting
for a couple of years, and there are barn owls a short distance away around
the south end of Lake Sammamish and this side of Issaquah. This has been
going on every night this past week, usually between midnight - 0200am.
Sounds like I might be a bit of a 'night owl' myself, huh. The bird always
seems to be 'commuting' to or from somewhere, just passing over on a direct
course, usually from north to south, but I haven't been able to detect a
silhouette against the glowing Seattle night sky. Maybe it's justa northern
hawk owl, no? <g> Thanks. --Richard
