Congregations like this are very common outside of the breeding season, for a few reasons.
One likely made a kill or discovered something to scavage and others investigated in hope of sharing a meal.
Eagles are no longer tied to their breeding territories and those which don't migrate south (of us) tend to move to the coast. Interior waters are generally frozen and the land is snow covered, severely limiting hunting and scavenging opportunities.
The open water, unfrozen intertidal zone, and abundance of seasonal food on the coast are attractive.
Red Breasted Mergansers and gulls, especially Ring Billed, are two principal winter foods.
Dead and winter-weakened animals are also easier to find in coastal areas.
The winter population of Eagles in the Passamaquoddy Bay region had held fairly constant for several decades at 200+.
Some travel considerable distance. One used to come Downeast every winter from Alberta.
Regards,
Ralph.

I wonder if this connected to some sort of fish run. Last year, in November we were there at low tide and counted at least 50 Bald Eagles, the vast majority of which were immatures or sub-adults.
Seems like it would be a good place for their cousin to hang out--the Steller's that is.
