I noticed this hawk as it made a short flight across my field of view. It landed on a branch, and we watched each other for a couple of minutes. The hawk preened, and fluffed its feathers. After I had all the photos I wanted, we got tired of each other. The hawk few off, a short flight back away, staying among the branches. Thanks to Charlie Quinn for the suggested ID: "How about an immature Red-shouldered Hawk?
That would be my best guess - the bib of dark streaks on the breast and the barring on the belly is a key feature." 10:57:50 am.
