Came across this after getting the Cornell bird-listening/identifying app. Pretty cool!
And some good photos in there , too.

Who doesn’t luv a chubby birb?
A very nice selection of calls! (Though starting the list with a Barn Owl without any prior sound to let you know how l of us your volume is set is a tad cruel!)
Different vocalizations can help differentiate species, like the Eastern and Western Screech or Northern and Southern White Faced Owls.
Their voices are also unique, and they can tell other owls apart. One can differentiate its mate from an outsider, for example.
They are also not limited to one or two types of sounds, but I’ve seen some estimates at around 2 dozen, from sounds they make as babies asking their parents for help to adult courting and defensive calls.
I was surprised on our Halloween nighttime walkthrough that Elliot, our Great Horn, made a noise that sounded like a very large croaking frog. I’ve heard a lot of GHO noises, but never that one!
Like seemingly everything else about them, owl voices are a lot more complex than they first seem.
