Taxonomy

French: Épervier des Nicobar German: Nikobarensperber Spanish: Gavilán de Nicobar
Taxonomy:

Astur butleri

Gurney, Jr

, 1898,

Car Nicobar

.

Traditionally combined in a species-group with A. badius and A. brevipes, and often also A. soloensis and A. francesiae (see A. badius). Sometimes considered a race of A. badius, but quite different in plumage (especially that of juvenile), in structure (short-winged) and in habitat choice (upper storeys of forest). Two subspecies recognized.

Subspecies and Distribution
  • A. b. butleri (Gurney, Jr, 1898) – Car Nicobar I (N Nicobar Is); possibly extinct.
  • A. b. obsoletus (Richmond, 1902) – Katchall I and possibly Camorta I (C Nicobar Is); individuals recently recorded on Nancowry probably of this race#R.
