CONSERVATION PRIORITY SETTING FOR BIRDS IN LATIN AMERICA The Nature Conservancy’s Wings of the Americas Program and the University of Arkansas, Center for Advanced Spatial Technologies
This project was designed to develop and distribute high quality bird distribution data that could be used as a tool to help determine conservation priorities in Latin America. During the course of the project, a comprehensive list of bird species of conservation concern in Latin America was generated, using a consensus of opinion from a variety of sources. The list includes species considered of conservation concern by the Conservancy and the Network of Natural Heritage Programs and Conservation Data Centers; IUCN/BirdLife International; and Parker, Stotz, and Fitzpatrick in their publication “Neotropical Birds: Ecology and Conservation.” Existing geographic range information for each species was collected and converted into a digital mapping format. The format used was a 15-minute grid cell base and all ranges were placed into the WORLDMAP biodiversity mapping software package. A total of 1289 species were included in the data base, out of which 164 species of conservation concern are present in Mexico, 74 of them endemic to the Country (shaded). Bird Species of Conservation Concern are defined for this exercise as any Latin American specie considered as:

G1, G3/4 Global Ranks proposed by The Nature Conservancy; G1 = Critically Imperiled-Critically imperiled globally because of extreme rarity or because of some factor(s) making it especially vulnerable to extinction. G2 = Imperiled-Imperiled globally because of rarity or because of some factor(s) making it very vulnerable to extinction or elimination. G3 = Vulnerable-Vulnerable globally either because very rare and local throughout its range, found only in a restricted range (even if abundant at some locations), or because of other factors making it vulnerable to extinction or elimination. G3/G4 = Uncertainty about the exact status of a taxon, which might be Apparently Secure-Uncommon but not rare.
Other taxa of recent description or that have been elevated from subspecie to specie, after the publication of the above mentioned documents. Bird Species of Conservation Concern distribution data for Mexico was taken from Howell, S.N.G. & Webb, S., 1995, A Guide to the Birds of Mexico and Northern Central America. Oxford University Press, Oxford, UK., and noumerous other aditional publications.
