Resumen:
Riparian habitats are important sites for avian conservation in western North America. These sites are also places of increasing human exploitation due to water availability and vegetation composition. Degradation and habitat patchiness of these systems may cause declines in avian species that are obligate breeders or use these habitats as corridors during migration. Our objective was to examine species composition and diversity of birds inhabiting a patchy Mesquite landscape in central Mexico. The study was conducted in the Salado River watershed in the Tehuacan-Cuicatlan Biosphere Reserve. We conducted bird censuses using circular plot surveys in four zones of similar size differing mainly in proximity to town. We compared bird presence and density with plant coverage and density measured at the same points. We recorded 80 bird species, 53.6% of which were winter migrants. The four zones studied were not statistically different in bird species composition but differed in bird densiti
