Species Description
The Hen Harrier (Circus cyaneus) breeds in the Northern Hemisphere in parts of Canada and Northern Eurasia. Hen Harriers can grow from one and a half to two feet long with up to a four foot wingspan. Hen Harriers exhibit sexual dimorphism, as the females are one and a half times larger than the males. Hen Harriers inhabit open terrains such as moorland, bogs, and farmland; in their habitats, Hen Harriers stealthily hunt small animals and birds. When trees are planted, Hen Harriers lose a lot of their habitat and are forced out of locations where forestry is prevalent. Four to six white eggs are laid when breeding, and Hen Harriers cover a large area with about 1.3 million birds covering 1-20 million square kilometers. Even with their diverse population, illegal hunting causes regional threats of extinction.
