I went to Oxbow this morning hoping the Red-sholdered Hawks reported by Fred Petersen might be around. They weren't, but on my way back to the car I spotted a Peregrine Falcon perched in one of the tall dead trees in the old burn area. I decided to wait and see if I could get some pics of it flying. While I was waiting, a male Kestrel landed nearby. A minute or two later a female flew right under the Peregrine , then over to another tree where the male joined her. I think this is the possible nesting pair that Fred also reported. There was no interaction between the Kestrel's and the Peregrine. But a Magpie promptly flew ingot the tree below the falcon and began a one-bird mob. The falcon stretched a bit and moved to a different spot on the branch. The both birds took off. I'm not sure which went first, but it looked like the falcon was after the Magpie when the they dropped down behind some trees and out of sight.
Here are links to a couple of the pics I got.
