Coopers Hawk Hunting Near Bird Feeder

Looking out my home office window, I watched this awesome rapter, the sharp-shinned hawk, tenaciously walk around a bush near my bird feeder where two sparrows were hiding. The squirrel was also fascinated by this hunt. The hawk's attempts lasted about 15 min. until he finally fly away when raccoons arrived. The raccoons also heard the birds rustling, peering into the bush and the birds flew off safely. The next day, the hawk returned and made two attempts to grab a pigeon, pinning the second pigeon to the ground, which I also vidoed until I decided to intervene and broke it up. This happened in my West Seattle yard.
[Update Dec. 2011: Thank you to all you smart birders who identified this fellow as a Coopers Hawk. My title said "Sharp-shinned Hawk" for a year, but I've just corrected it to "Coopers Hawk". I wanted to explain for future visitors why the comments were all pointing it was a Coopers and being confused since my title says so - now.
