Last year I watched a hawk in my backyard spend about a half hour eating a bird. I got some good pictures, but nothing like the great picture above!! After it flew away, the yard was littered with feathers!! I have to say, I would have enjoyed watching the hawk take down a squirrel - it's one less squirrel crawling around in my eaves!!
Also, last spring, there was either a hawk or an eagle nesting in a windowsill at Somerville High!
