Title A name given to the resource Urbanizing the wild: shifts in bird communities associated to small human settlements Urbanizando la naturaleza: cambios en las comunidades de aves asociadas con asentamientos humanos pequeños Creator An entity primarily responsible for making the resource Ian MacGregor-Fors, Jorge E Schondube Description An account of the resource Urbanization limits the number and type of species that can colonize urban environments. As habitat change and large abundances of urban exploiter species have been related to changes in urban bird communities, we evaluated shifts in the bird communities in 2 small sized settlements, 1 with exploiter species and one without them. Our results show that bird species richness decreases when an area becomes urbanized, regardless of the presence of urban exploiters. While bird densities were low in the human settlement lacking urban exploiters, they were high in the other settlement due to the numbers of 2 urban exploiter species. Bird community evenness decreased from forests to the human settlement lacking urban exploiters, while decreased importantly in the settlement dominated by urban exploiters. The composition of bird communities was highly similar between forest conditions and the settlement lacking urban exploiters, and highly different to that from the settlement with urban exploiters. Our results thus suggest that when an area becomes urbanized, changes in habitat structure and their subsequent invasion by urban exploiter species generate a significant loss in bird species richness, favoring those species that can inhabit and exploit the new urban condition.La urbanización limita el número y tipo de especies que pueden colonizar a los ambientes urbanos. Debido a que los cambios de hábitat y las elevadas abundancias de especies explotadoras de ambientes urbanos han sido relacionadas con cambios en las comunidades de aves, en este trabajo evaluamos los cambios en las comunidades de aves en dos asentamientos humanos pequeños, uno con especies explotadoras y otro sin ellas. Nuestros resultados muestran que la riqueza de especies de aves disminuye cuando un área es urbanizada, sin importar la presencia de especies explotadoras. Las densidades de aves fueron bajas en asentamientos humanos sin especies explotadoras y fueron significativamente más altas en el otro asentamiento, básicamente debido a la presencia de dos especies explotadoras. La equitatividad de las comunidades decreció de los bosques a los asentamientos humanos. La composición de las comunidades de aves fue más similar entre las condiciones de bosque y el asentamiento sin especies explotadoras, y altamente diferente en relación con el asentamiento con especies explotadoras.
