Circus Cyaneus, commonly known as the Northern Harrier, is a medium-sized raptor found across North America and parts of Europe and Asia. This bird is easily recognized by its long wings, slender body, and distinctive facial disc, which helps it locate prey through sound. The Northern Harrier primarily hunts small mammals and birds, often flying low over fields and marshes. The breeding season for Circus Cyaneus typically occurs in spring, with nests built on the ground in tall grasses or reeds. Females lay 3 to 7 eggs, which both parents help to incubate. This species is known for its unique hunting style, gliding gracefully while scanning the ground for movement.
