So, twice in one day last week I saw a hawk that I thought was a Coopers Hawk due to the large broad wings and abnormally long tail.  I was driving at the time, but I noticed a conspicuous white rump patch, large white wing bars, and jet black wingtips.  The rest of the underside was an indistinguishable brown from where I was.  When I came back to look for actual pictures, it didn't actually seem to match anything.  Maybe just an interesting variation on a Coopers Hawk?
