[birding] Cooper's Hawks quarreling?

[Linda Fink]

A couple days ago, I heard a sound I didn't recognize from in front of
the barn. A similar sound started up from the other side of the house. I
could see neither culprit. After a bit, one of the callers erupted into
what sounded like a Cooper's Hawk scold to me. So I taped the sounds and
put them on youtube. Here's the URL.

I scan back and forth toward where each sound was coming from. After
turning off the camera, I wandered around and finally did see the now
silent hawk in front of the barn. It was high in a leafless maple,
mostly hidden, with its back to me. My impression was the size of a
Cooper's. As soon as I lifted my binocs, it flew down and out of sight,
accipiter-like. Meanwhile, it turned out my husband who was by his shop
behind the house had seen the other hawk and said it "seemed smaller
than a red-tail but had a light front like a red-tail". He did not have
binocs and just noticed that it was making a "weird noise".

So, are they Coopers?

Thanks!
