Swainson's Hawk living large

Dropping off some dry-cleaning this morning, I looked up to see a cluster of raptors circling over the Beverly Hills Four Seasons (Doheny/Burton Way). Three Red-tails and a Swainson's Hawk. I almost never see Red-tails south of Sunset Blvd. in the Hollywood/Farmer's Mkt area, so they caught my eye. They continued east in a straight line out of sight.
