Taxonomy

Taxonomic note

Phaethornis longirostris, P. mexicanus and P. baroni (del Hoyo and Collar 2014) were previously lumped as P. longirostris following SACC (2005), and before then were also lumped with P. superciliosus as P. superciliosus following Sibley and Monroe (1990, 1993).

Population justification: The global population size is unknown given recent taxonomic splits.

Trend justification: The population trend has not been investigated, but declines are suspected as a consequence of the loss and degradation of forested habitat. Tree cover within the range is lost at a rate of 8% over ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). As the species is not strictly forest-dependent but also occurs in secondary growth, edges and plantations (del Hoyo et al. 2020), the rate of population decline is unlikely to exceed the rate of tree cover loss. Tentatively, declines are here placed in the band 1-19% over ten years.
