Owl in Ames, Iowa (2 Viewers)

No pictures yet, though I did get a peek when my son pointed it out in one of our trees using a flashlight, so I can be quite sure it is a sort of owl. I won't venture to paint it in words except to say probably between 14-16 inches in height while perched in the tree, and colored in a gray/black pattern, not real distinctive (except insofar as all owls look pretty otherworldly). To be honest I'm not very confident of either of those descriptions. I didn't get a great look.

But maybe someone can nail it down by the sound: a shriek like tires squealing, some 2 seconds in duration, with a slightly rising pitch at the end before it cuts off, covering just a half step or so on the musical scale. Then there is a pause of 20-25 seconds before it makes the same sound again, possibly from a different tree, a neighbor's yard, down the street... Volume of the shriek varies, and is sometimes very faint, which is what leads me to think it is moving around.

We've only seen it the one time, and although tonight was the first night I have heard it, my wife says she has been hearing it for weeks. (She is a lighter sleeper than I am, and stays up later.)

Any guesses based on my poor information? If not, I'll try to get a picture next time we hear it very close to the house - or make a sound recording.

The only other call I am familiar with locally is the barred owl's "who cooked for you" -- this is obviously nothing like that call, but much more discordant.
 
Followup: looking through pictures in a bird book this morning, my wife and son were sure it was an ordinary barred owl, though smaller than the 20-24 inches our book says they are supposed to grow to. Which made me wonder what that vocalization was about, as the only sound I associate with a barred owl is the hooting call mentioned in the above post.

So I searched the web for "barred owl screech juvenile" and found this page. The recording they have sounds more mellow than the tires-squealing sound we heard so close to us, but the rising pitch of it is the same. Mystery solved, I think.
 
here it is

Shot minutes ago while my wife was holding a flashlight and we were both getting devoured by mosquitoes. So not the sharpest picture ever, but should be enough to make the ID.

Barred owl, yes?

Very much a Barred Owl, and an adult. Many birds do have a number of calls other than those with which they are typically associated. The "screams" listed on this site seem to fit your description of a sound like tires squealing: http://www.owlpages.com/owls.php?genus=Strix&species=varia The site says the calls were recorded during flight.

Best,
Jim

I ended up a little obsessed with this question |=)| and talked to a wildlife veterinarian at the local university and showed her the picture. She said that based on the call, it can only be a juvenile, albeit a large one. I guess that makes it an adolescent.

Adults will only make that call occasionally when in grave distress themselves or in the presence of distressed young ones; not routinely night after night as ours has done. I have no doubt there is a variety of calls for barred owls, but she recognized this one from my imitation... something I couldn't do online!
