I noticed the seagull gave him a wide berth....
We have bald eagles flying over the house all the time. The gulls give them a wide berth but the crows frequently dog them.
It's because they raid their nest for eggs/young...like crows and ravens do to smaller birds all the time...and (shocka!) none of them like it.
Funniest chase I saw was about 5-6 smaller birds like blackbirds chasing a big 'ol raven taking turns diving at it.
I see some eagles at home, mostly in-transit between river systems, at the lake all the time. The loons belt out their warning cry whenever one is overhead, sometimes they just come swooping over the house or parallel to the shore or are circling and diving.
Last week I saw an Osprey, used to have a nesting pair years ago...wonder if a pair is setting up or one was passing through. I've seen them at Yellowstone catching fish, not at my lake, eagles yes. Last year one pinched a decent sized northern and had it in my neighbors tree while he munched it. One of the nesting pair we have on the western shore.
Oh, my father watched an eagle get in a death-circle with a hawk...hawk can fly quicker and tighter, but an eagle can make better use of currents...he said they would circle up and then the eagle would try to turn and dive and the process just kept going on for quite a while till the larger eagle got tired of it.
