Indigo-capped Hummingbird Amazilia cyanifrons



Taxonomy

Taxonomic note
Amazilia cyanifrons and A. alfaroana (HBW and BirdLife International 2017) were previously lumped as A. cyanifrons (del Hoyo and Collar 2014), but A. alfaroana is now recognised as a good species following Kirwan and Collar (2016), who examined the sole specimen and found species-level differences from cyanifrons and no evidence of characters suggesting that it is a hybrid, with the conclusion that - subject to any future molecular analysis - it is best treated as a separate species.

Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).

Trend justification: Its wide altitudinal range, combined with an apparent adaptability to man-made habitats, suggests that the species is relatively secure at present (Weller and Boesman 2017).
