Falco severus

Horsfield

, 1821,

Java

.

Probably closest to F. longipennis, the two perhaps members of the F. subbuteo group (which see). Variation in size and plumage slight and clinal; papuanus darker and on average slightly smaller than nominate, but differences possibly insufficient for racial differentiation. Two subspecies tentatively recognized.

Subspecies and Distribution

  • F. s. papuanus Meyer & Wiglesworth, 1893 – Sulawesi E through Moluccas to New Guinea, Bismarck Archipelago and Solomon Is.
