Hummingbirds (Trochilidae)

Sapphire-vented Puffleg (Eriocnemis luciani) - HBW 5, p. 640

French: Érione catherine German: Langschwanz-Höschenkolibri Spanish: Calzadito Colilargo Norteño
Other common names: Long-tailed Puffleg

Taxonomy: Trochilus luciani Bourcier, 1847, Guaca, Ecuador.
Often considered conspecific with E. sapphiropygia, and intermediate specimens exist, but morphological differences support treatment as separate species. Doubtful species “E. soederstroemi” is regarded by some authors as a hybrid of present species and E. nigrivestis, or a race or aberrant form of E. godini. “E. isaacsonii”, known only from three Bogotá trade skins which are not identical, may be a hybrid of undetermined species of Eriocnemis x Heliangelus. Monotypic.

Distribution: Andes of SW Colombia (Nariño) and W Ecuador.
