Unusual bald eagles' (Haliaeetus leucocephalus) flying behavior?

Observation by Niina Jyränen:

On Summer Bay Road near the Unalaska landfill there were two bald eagles flying together, doing swoops and changes in the air. Usually this time of the year (early June) bald eagles hatch their eggs so one of the eagles would stay near the nest? Is this kind of flying behaviour normal or what could be an explanation for this?

Comments from LEO Editors:

According to the American Eagle Foundation, during breeding season, male bald eagles do much of the food provisioning, while female eagles remain closer to the nests. Depending on food availability, male eagles may travel farther distances than females. Bald eagles are often observed soaring alone, however more than one eagle may be seen if there is an especially plentiful food source, or if the area provides protection from the strong winds characteristic of the Aleutian Islands.
