Abstract: Geographical distribution and habitat characterization of the Trochillidae family (Birds) in the state of Guerrero, Mexico. The distribution and abundance of species of the Trochillidae family is usually influenced by the flowering and phenology of plants used by them as a feeding source, mainly in primary forest, so that changes in vegetation cover could represent affectations in their populations. We analyzed and characterized the geographical distribution and habitat for 22 species of resident hummingbirds in the state of Guerrero using the vegetation and land use maps of INEGI Series IV (2007-2010). Distribution models were generated with the Genetic Algorithm for Rule Set Production (GARP), using historical records of scientific collections and fieldwork (2001-2009), in combination with climatic and topographic variables. Of the 22 modeled species, six are endemic to Mexico, the same number of species found in a risk category. The highest concentration with regards to richness, endemism and number of threatened species of hummingbirds occurs in the biotic province of the Sierra Madre del Sur. However, the hypothetical distribution of most of the hummingbirds occurs in disturbed sites or agroecosystems as a result of changes in land-use. For Campylopterus hemileucurus , Lamprolaima rhami y Heliomaster longisrostris , their hypothetical distribution is highest in areas of primary vegetation. The areas of highest concentration of hummingbirds do not coincide with the Areas of Importance for the Conservation of Birds in Guerrero, considering that, despite its diversity and its extreme popularity among human beings, from the conservation perspective hummingbirds have received relatively little attention.
