I've seen this bird in the backyard many times and I finally got a good photo of it yesterday. I think it's a juvenile red-tailed hawk, judging from the picture in The Sibley Guide to Birds. I noticed a bunch of small gray feathers right near this fence post, perhaps evidence of its latest meal. This hawk is probably looking for mice and voles, too, along with the great-horned owls which I heard hooting to each other last night.
