Hummingbirds (Trochilidae)

Rufous-vented Whitetip (Urosticte ruficrissa) - HBW 5, p. 644

French: Colibri à sous-caudales rousses German: Rotsteißkolibri Spanish: Colibrí Puntablanca Oriental

Taxonomy: Urosticte ruficrissa Lawrence, 1864, Ecuador.
On the basis of behaviour, genus belongs to a clade including Eriocnemis, Haplophaedia and Ocreatus. Genus sometimes merged into Adelomyia. Sometimes considered conspecific with U.benjamini, based on intermediate characters of birds from NE Peru; this population has often been awarded race intermedia, but differences probably constitute a cline within U. benjamini; Peruvian population of U. benjamini sometimes transferred to present species; more study required. Monotypic.

Distribution: E slope of SC Andes of Colombia (Huila, SE Nariño) to E Ecuador.
