The Northern Harrier (Circus hudsonius) is a migratory bird of prey that breeds in the northern region of the northern hemisphere in Canada and the United States; it migrates to southern parts of the United States, Mexico, and Central America in the winter. The species like to occupy moorland, bogs, prairies, marshes, and other assorted open areas. They have long wings and tails, and like other harriers, the Northern Harrier has distinct male and female plumage. The adult male has a dark gray plumage and spectral aura, and the adult female’s plumage is more rufous. A majority of the diet is small mammals like voles, cotton rats, and ground squirrels.
