White-tailed Hummingbird has only a small geographic range, within which habitat loss has been extensive (Collar et al. 1992, BirdLife International 2013). The IUCN Red List status for Blue-capped Hummingbird is Vulnerable (BirdLife International 2013), due to its restricted range and population size (a world breeding population of 10,000-19,999 mature individuals and a resident distribution of about 4,000 km2 according to BirdLife International 2013). It is considered threatened under Mexican Law (NOM-059 SEMARNAT 2010). White-tailed Hummingbird also is listed on Appendix II of CITES. This species also is considered a species at greatest risk of extinction by Partners in Flight (Berlanga et al. 2010). Based on determinations of habitat loss, Berlanga et al. (2010) estimated that 15-49% of its population has been lost during the last century.

In proper habitat, however, the relative abundance of White-capped Hummingbird is assessed as fairly common to common (Binford 1989, Collar et al. 1992, Navarr0 1992, Howell and Webb 1995).

Effects of human activity on populations

The threatened status of White-tailed Hummingbird is entirely due to habitat loss, for agriculture (Collar et al. 1992, BirdLife International 2013) within its restricted geographic range. White-tailed Hummingbird also faces future threats from climate change.
