Northern Harrier — Water Connection

During migration, Northern Harriers, like other raptors, are reluctant to fly over long stretches of open water, although they do take advantage of the strong thermal air currents that rise over land and are especially strong at the border of land and water. As a result, good places to see migrating raptors are at “funneling points” at the ends and edges of the Great Lakes.

Though its prey is usually fairly small, a Northern Harrier may take larger animals like rabbits or ducks. Harriers have been known to subdue large prey by drowning them.
