When my parents lived in Westport, CT, a very young bald eagle visited town. It perched on some pilings and some girders on a bridge. Newspapers aid he was a bald eagle, but I wouldn't know. The colors did not seem very distinct, and I didn't think coastal CT was within their range. It was a very urban area!
I think the appeal was a fish store. Could they have been throwing fish guts right back into the river? The hoards of seagulls seemed to think so.
Those gulls were sure perturbed by the presence of the young eagle! They complained a lot and flapped around agitatedly.
Eventually they would work up the courage to scrounge around the fish store, which would make the eagle wake up and take a lazy circle around the area. Just "flap flap cruise ...". That had the same effect on the gulls as a strafing run by a squadron of Luftwaffe.
Then the eagle would fly back to his piling and apparently go back to sleep.
People flocked around with cameras. After a week or two, he moved on.
