Eastern buzzard or Japanese buzzard (Diều Nhật Bản, Buteo japonicus)

The eastern buzzard or Japanese buzzard (Buteo japonicus) is a medium to large bird of prey that is sometimes considered a subspecies of the widespread common buzzard (Buteo buteo).

The bird is native to East Asia and some parts of Russia and South Asia, with some birds wintering in Southeast Asia.

The Latin/Greek meaning of Accipitridae is the family of "hawks," derived from the Latin word "accipiter" (hawk) and the taxonomic suffix "-idae" (family). While "accipiter" is the primary source, some scholars suggest a potential connection to the Ancient Greek words okypteros ("swift-winged") and okys ("swift") and -pteros winged. 
Buteo (Latin): Refers to a buzzard, a type of bird of prey.
