Falco longicauda

Lesson and Garnot

, 1828,

New Guinea


Part of monophyletic clade with Hamirostra and Lophoictinia#R. Closely related to H. infuscatus, and has been considered conspecific, but separated by plumage. Proposed race fraterculus (from Yapen I) barely distinct from longicauda; minimus (W Papuan Is and Aru Is) supposedly smaller, but size varies clinally with altitude in mainland New Guinea (birds smaller in coastal lowlands, larger in highlands). Treated as monotypic.


W Papuan Is, New Guinea (including islands in Geelvink Bay) and Aru Is.
