Black morph hawk (photos)

I disturbed a hawk who was eyeing the La Franchi freerange chickens in the field across from the Nicasio Reservoir. Somehow I don’t think the Alsatian guard dogs will be able to keep this fellow at bay. What kind of hawk, it’s like a Mexican hawk, brown all over. Cooper’s hawk comes to mind. Not a red tail. Darker. Not striped, so not a red shouldered hawk, more like a red tail hawk, but melanistic. There are several dark hawks along Nicasio reservoir. I have many photos of them. He was upset with me because I was too close to him—and his  coveted chickens....he turned around on his post to give me a baleful stare. If looks could kill. I was shooting from inside the car but clearly that didn’t fool him. He stood his ground. Geoff Davis said, Yearling redtail—only ONE stripe on tail feathers, immature and hungry and been wet. I thought maybe his fishing expedition failed, and he was trying his luck in greener pastures.
