When I go into my garage right after work it’s usually to fill our bird/squirrel feeder. I’ve noticed for the last couple months that when I go into the garage in the late afternoon now, I’ll hear the crows and scrub jays start to call each other moments later. They’ve usually found all the in-shell peanuts in the feed within an hour.

Yep, pigeons can differentiate human face traits (generally speaking).
Though many keepers have told me that raptors tend to distrust them if their clothing is different (shirt, hairstyle, hat, glasses, etc.)
Haven’t heard the same behavior from columbidae.
