Density and habitat associations of the Altamira Yellowthroat Geothlypis flavovelata in Veracruz, Mexico: an endemic vulnerable species

The Altamira Yellowthroat Geothlypis flavovelata is endemic to north-eastern Mexico, with a restricted distribution due to the spatial arrangement of its major habitat: wetlands.

Description
Summary:The Altamira Yellowthroat Geothlypis flavovelata is endemic to north-eastern Mexico, with a restricted distribution due to the spatial arrangement of its major habitat: wetlands. Given the lack of information regarding this vulnerable and endemic landbird, here we describe and analyse the sites where we recorded it in Northern Veracruz, as well as its population density, and natural history information. Our results show that the average density of this endemic yellowthroat is 1.006 ind/ha, with more individuals recorded in Tecolutla when compared to Tuxpan. We found a strong association between the Altamira Yellowthroat and southern cat-tail Typha domingensis, although we found scenarios under which the presence of the cat-tail was not a determinant of Altamira Yellowthroat presence. In light of the strong anthropogenic pressures on wetlands in the region, the Altamira Yellowthroat has become highly vulnerable. Thus, if we aim to preserve this endemic species, together with other wetland-dependent species, it is crucial to moderate –and even stop– human pressures on these ecosystems and mitigate past damages.
