Résumé
Community composition, species densities and distributional patterns of breeding birds were studied during the late spring and early summer of 1985 on a bajada in southern New Mexico. Twenty-eight species were included in the sample, of which the 13 more commonly found were chosen for statistical analyses. Mean densities of all species were compared among four sampling transects, as well as among three physiognomically distinct habitats (i.e., basin slope, creosotebush, and piedmont). Comparisons between transects yielded a few significant differences that cannot be attributed to features of the habitat. Significant variation among habitats was found for most species ; the creosotebush band had the lowest densities and the other two varied mainly in species composition.
