Don't know what species chased it, but the window in a conference at my old office had the oiled image of a pigeon's head (eye, beak) and wings (even the alulae) where it crashed into the window. Like seals that chase salmon into gill nets, even a "small" hawk can eat pigeon if there are good windows around.

I will add to that that Cooper's Hawks take pigeons regularly. I photographed one eating a Rock Pigeon at Magnuson Park in Seattle some years ago, and I have actually seen 5 Band-tailed Pigeons killed by Cooper's Hawks in our yard in the 30 years we have lived here. All but one of the hawks were females, but a male took one by causing it to fly into a window, which stunned it enough for the hawk to capture and kill it. Male Cooper's Hawks are the same weight as Band-tailed Pigeons, females considerably larger.

> Bob, regarding your p.s. about the possibility of the Prairie Falcon that you saw taking a Rock Pigeon, I would say that there is a good chance that it could. When I was visiting the Garden of the Gods near Colorado Springs, CO, in February, 2000, I saw a Prairie Falcon hunting the Rock Pigeons that were on the cliffs. I didn't see it catch one, but it sure was trying.

One time a Cooper's Hawk took a Rock Dove off my feeder, and then struggling, flew with it to the bottom of the hill that was my back yard. There on the ground the Coop and the Rock Dove wrestled, desperately. It was a wild, lengthy tussle, but in the end the Coop won. The Coop then ate on the Dove until full, so full that the Coop could hardly move. Eventually it managed to hop up on the nearby fence. There it sat for a few hours before eventually flying away. So if an overachieving Coop can take a Rock Dove, I would guess that a Prairie Falcon could too.
