I know what a redtail hawk looks like and this is NOT one. It has a relatively "narrow" wing profile, seems smaller than a redtail hawk. It swoops and dives. It has rather long, straight tail feathers. Color is dark-ish. Im tempted to say a falcon of some sort. It is also NOT a sparrow hawk, because those are about the size of a bluejay or slightly larger. This hawk is bigger, maybe the size of a large crow. I started looking around at pictures, at first thinking it might be a harris hawk, but the tail feathers arent right. This bird has the tail feathers of a falcon - long and straight when in flight. Ive seen sparrow hawks in flight and "hovering" and it acts very similar.
