[EBB Sightings] Swainson's Hawks in another nearby field

When we went on Saturday 7/2 in the late afternoon, the Lindemann Road 
field near Byron Highway was bereft of Swainson's hawks, although egrets, 
herons, blackbirds, and corvids were all over the place.

But we drove up to Bruns Road and turned left, where we found a few dozen 
hawks near the southeast corner of Byron Highway and Bruns Road.

Wiser birders, pray tell: how can you best tell they are Swainson's Hawks, 
and is this normal behavior for them, to hang out in big groups at buffets?

The only resemblance I saw to any guide book pictures (among Sibley, 
National Geographic, Peterson guide, and Peterson advanced hawks book) was 
to the Sibley illustration of a late first year juvenile. Several of the 
live ones had almost entirely white faces.
