About The Hen Harrier

Intermediate in appearance between the slim bird hawks (genus Accipiter) and thick-set buzzards (genus Buteo), the Northern Harrier is most easily identified by its size (17 ½ - 24 inches), long wings, long squared-off tail, and conspicuous white rump patch. Male Northern Harriers are light gray above and pale below, while females are solid brown above and streaked brown and tan below. Like most species of raptors, females are larger than males. The Northern Harrier is found widely across Eurasia (where it is known as the Hen Harrier) and North America. In the New World, this species breeds across Canada, Alaska, and the northern tier of the United States. In winter, Northern Harriers may be found from the southern Great Lakes and Pacific Northwest south to Mexico, Central America, and the West Indies. In the Old World, this species breeds across northern Europe and Asia south to Portugal and northern China, wintering as far south as North Africa and South Asia. The Northern Harrier inhabits a variety of open habitats, including grassland, marshes, and agricultural fields. This species avoids built-up areas and forests. The diet of the Northern Harrier consists primarily of small mammals and songbirds. Due to this species’ preference for open habitat, Northern Harriers may be most easily observed flying low over the tops of tall grasses in search of prey. Less frequently, Northern Harriers may be seen soaring high over open areas, displaying their characteristic long tail and wings. This species is primarily active during the day.

Hen Harrier (Circus cyaneus)
Not 100% sure on ID. Originally ID was Pied Harrier, but the dark trailing wing and gray head point to rarer Northern Harrier.
