I was in the back yard taking a break from all day renovation work when I heard that sound again.
Large group of Crows really noisy in the front of the house, not as close this time. I spotted a Red Tail in the same tree with the Crows.
The Red Tail took off headed East and the Crows continued their pursuit in the other direction.
A few minutes pass and here come the Crows again in hot pursuit of a Great Horned Owl.
Took a few snaps not very good but you get the idea. I had to crop it and brighten it..

Weird, the crows don't look real
p.s. Someone in Milton submitted an image of a Barred Owl to the local news paper taken Christmas eve.
