Tamaulipas Pygmy-Owl Glaucidium sanchezi



Conservation Status

The IUCN Red List status for Tamaulipas Pygmy-Owl is Least Concern (BirdLife International 2015); its population size (20,000 – 49,000 mature individuals) and distribution (27,200 km2) do not meet the thresholds for classification as Vulnerable (BirdLife International 2015). It is considered Endangered 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

Tamaulipas Pygmy-Owl faces heightened risk because of its specialization on threatened tropical highland forest (cloud forest) habitats. The primary threat to this species is loss of this habitat due to unsustainable logging, wood harvesting, clearing for agriculture, and livestock grazing. It also faces threats from climate change that will only become more severe over time.
