Narrow-tailed Emerald (Chlorostilbon stenurus)


French: Émeraude à queue étroite German: Schmalschwanz-Smaragdkolibri Spanish: Esmeralda colifina

Panychlora stenura

Cabanis and Heine

, 1860,

Mérida, Venezuela


Closely related to C. poortmani. Very similar to and apparently sympatric with race alice of latter. Race ignotus sometimes considered synonymous with alice, or treated as a hybrid. Birds of Colombia have been separated as race acuticaudus, but regarded as doubtfully valid. Two subspecies recognized.
