Blue-tailed Hummingbird is common and widely distributed, but its natural history is very poorly known. Its foraging ecology and breeding biology are almost completely unknown. There also is no information regarding demographic factors such as life span and survivorship, dispersal, or population regulation. The taxonomic status of the three subspecies, especially of the extremely poorly known population (?) of Costa Rica, merits further investigation, as does the report of extensive hybridization or introgression with Berylline Hummingbird (Amazilia beryllina) in El Salvador.
