What is a "montagu's harrier"?

A Montagu's harrier is a medium-sized bird of prey known for its graceful flight and striking appearance. It features long, narrow wings, a slender body, and a distinctive facial disk. The male has pale gray plumage with black wingtips, while the female exhibits a brown coloration with streaks and a white rump. This harrier is known for its agile hunting technique, gliding low over grasslands and marshes to locate its prey, which primarily consists of small mammals and birds. Montagu's harrier is a migratory species, nesting in open habitats across Europe and parts of Asia during the breeding season and spending the winter months in Africa. The female constructs a nest on the ground, where she lays a clutch of eggs.
