Other Observations:

A very unusual sighting (perhaps never seen before at the site???) was a group (the word "flock" doesn't sound right for this) of six Golden Eagles (4 adults, 2 unaged) at 2 pm, flying north (opposite to the migration direction) over Mount Patrick. They then milled around for 15 or 20 seconds over the north ridge of Patrick, interacting and diving, before somehow dispersing (two continued north lower down, but I didn't see where the other four went). I've never seen more than two non-migrants at a time that I can remember, so what brought six together at the same time seems a bit of a mystery. Maybe there was some carrion further south that attracted some non-migrants?? I don't know why so many would fly off together, though.
