The Houston area is very popular for overwintering hawks, primarily red tails, this fall I've already had a hawk dive into the rough of the golf course about 100 yards a way and then casually fly over my yard with a fat rat in it's talons.
Last winter I noticed 4 fat doves on the ridge of my roof as backed out one morning, 10 seconds later I realized I forgot something and turned around to get it, as I pulled into my driveway I noticed no doves but thousands of underfeathers roling down my roof - I guess this was the hawk's version of a breakfast buffet
