MACGREGOR-FORS, Ian; SCHONDUBE, Jorge E.; MORALES-PEREZ, Lorena y QUESADA, Javier. Geographic-altitudinal range extension and suburban habitat use of the Grey-crowned Yellowthroat (Geothlypis poliocephala). Rev. Mex. Biodiv. [online]. 2008, vol.79, n.2, pp.533-534. ISSN 2007-8706.
The first record of the Grey-crowned Yellowthroat (Geothlypis poliocephala) in the Transmexican Volcanic Belt biogeographic region (Mexico), within the Morelia city suburbs is presented. Sites were this parulid was sighted / captured were located 427 m higher than its described altitudinal range. This could be due to 2 factors: 1) urbanization generates suitable habitats for this species in periurban areas, and 2) temperature values have increased in the region where the city of Morelia is located. These factors allow that a lowland bird species can inhabit in more elevated areas. Thus, our records suggest that the Grey-crowned Yellowthroat can be catalogued as potential to use suburban environments when these are similar to those used by the species on its natural distribution area.
