Very high speed attack with no warning. Got me on the left ear. Didn't bleed but was pretty sore. Other cyclist nearby said his girlfriend had also been clipped on the left ear, so I guess this is the side it goes for. I would highly recommend walking through this area.
Until now this bird seems to have been content to only swoop those riding on the road - today he decided it was time to give those on the bike path a go! No contact, but several swoops
