I can't figure out what species of bird this is. It was on the south shore of Turtle Pond. Is it just a strangely marked Rock Pigeon? If you know, please leave a comment.
I wasn't able to get close to this bird, so I'm sorry if the photographs and movies aren't that clear.
After two days, it's clear it's a Rock Pigeon. The behavior confused me, but the white cere should have been the giveaway.
