Abstract

RAMIREZ-ALBORES, Jorge E.; GORDILLO-MARTINEZ, Alejandro  and  NAVARRO-SIGUENZA, Adolfo G.. Noteworthy records and avifauna in an area of the Sierra Gorda Biosphere Reserve, Guanajuato, Mexico. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.4, pp.1058-1064. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2015.06.017.

We report new records and range extensions for 7 bird species in the Biosphere Reserve Sierra Gorda, Guanajuato, Mexico. Five of these species (Trogon mexicanus , Ara militaris , Cyanocorax yncas , Euphonia elegantissima and Spinus notatus) extend their known distribution and 2 (Buteogallus anthracinus and Myiozetetes similis) were not reported for the state, in addition to 98 other bird species observed in this region. Our records indicate the importance of this region at state and national level as an important area for bird species richness and as contact area of tropical bird affinity distribution in eastern Mexico to the dry conditions with the Mexican Plateau, as well as the presence of indicator bird species of good conditions of forest habitats. A greater research effort will allow complete knowledge of the birds in the Sierra Gorda in Guanajuato and be able to assess the real state of conservation of the bird community and populations within it.
