Mexican Woodnymph Thalurania ridgwayi



Conservation Status

The IUCN Red List status for Mexican Woodnymph is Vulnerable (BirdLife International 2015) due to its small range (14,500 km2) and continued habitat loss. It has a world breeding population of 6000-15,000 mature individuals (BirdLife International 2015). It is considered Threatened under Mexican law (NOM-059 SEMARNAT 2010). This is also a species of high tri-national concern (Mexico-U.S.-Canada) to Partners in Flight (Berlanga et al. 2010), as a species at greatest risk of extinction. Based on determinations of habitat loss, Berlanga et al. (2010) estimated that 15-49% of its population has been lost in Mexico during the last century.

Effects of human activity on populations

Mexican Woodnymph faces heightened risk because of its specialization on threatened tropical deciduous forest habitats. The primary threat to this species is loss of this habitat type due to unsustainable logging, wood harvesting, clearing for agriculture, and livestock grazing.
