Pernis is a genus of medium-sized broad-winged birds of prey. Birdlife International recognises an additional fourth species the Philippine honey-buzzard (Pernis steerei), normally considered a subspecies of Pernis celebensis and lists it as Least Concern. They breed in temperate and warmer climates of the Old World, and are specialist feeders on wasp larvae. The two temperate species, the European and crested honey buzzards, are migratory. They breed in woodland, and are often inconspicuous except when displaying.
