Spanish: Gavilán Flanquirrojo
Other common names: Chestnut-flanked Goshawk, Chestnut-bellied Sparrowhawk
Taxonomy: Accipiter castanilius Bonaparte, 1853, South America; error, Gabon.
Apparently fairly close to A. toussenelii and A. tachiro, but distinguished by smaller size and long inner claw. Birds of W Zaire sometimes separated in race beniensis, on grounds of larger size. Monotypic.
Distribution: Nigeria E to Zaire River basin. Purported presence in Upper Guinea forests W of Nigeria requires confirmation.
