About These Birds
雀鹰
The Eurasian Sparrowhawk (<em>Accipiter nisus</em>) is a widespread and well-known raptor of the family Accipitridae (Hawks, Eagles & Kites), occurring across much of Europe and Asia. It is closely associated with forest habitats, including mixed woodland, conifer plantations, and wooded farmland where it hunts small birds with remarkable speed and agility. Detailed plumage and behavioral descriptions of this species are limited in the available literature for this record, though the species is known to display strong sexual dimorphism in size. …
