There was one such bird in my driveway this weekend - completely freaked out, yet unafraid of people. I got a stick, put it under him (which he then stood upon) and moved him out of the driveway. I didn't want to touch him in case he was still of the age in which he was seeing his parents for food (so my person-scent wouldn't be on him). He was gone an hour later - hopefully not into the belly of a local cat.
