Probably a hawk about to get some dinner...had one about like that swoop in full attack mode, with talons extended and wings cupped, in front of me on the hwy apparently chasing a mouse or a rat feeding on a road kill carcass at the edge of the grass at the shoulder earlier this week...'caused the wife to scream a litle in fright when it came within inches of her side of the windshield at 75+ mph...still don't know how I didn't hit him.
