A hawk visits the radio tower

Some kind of hawk visited the radio tower for a few minutes today. It could have been a red-tailed hawk - there are lots of them in Oregon, but I've never seen a hawk on our tower. They can usually be found perching on the power poles over freeways. I saw a heron on our tower once, but it's unusual to have interesting birds perch there. The picture was taken at the extent of my zoom, and I couldn't get any closer. Someday it will be fun to have a longer lens for moments like this. I then took some pix of the water and missed the raptor's flight off the tower.
