"Hoot. Hoot hoo-hoo hoot-hoo." (Thank you. Even if that did sound vaguely threatening.) *perches on Rex's head*
"Hoot hoot hoo, hoo-hoot hoo hoot-hoo." (I appreciate that, though I find it slightly disturbing that my murder seems to be a subject for group discussion.)
"Hoot-hoot hoo? Hooo hoot-hoo hoot?" (Successfulness of my species? Do you see any other owls around here?)
I don't like to toot my own horn but I know a bit of owl speak. I learned a greeting from a real nice couple of owls. and I like to think I picked it up pretty fast~ hoot hoot hoot-hoot hoot (I'm a stupid moron with a ugly face and a big butt, and I like to kiss my own butt)
"Hoot hoo-hoo. Hoo-hoot-hoo hoot." (Probably Meriadoc and Rudyard. They love messing with non-avians)
