|a We used mist nets to survey small migrant and resident birds of scrub habitats in arroyos and adjacent uplands of the northern Chihuahuan Desert during late February-early May 1993-1997. We captured 723 individuals of 49 species. Species diversity was greater in arroyos than in adjacent uplands. Black-throated sparrows (Amphispiza bilineata), white-crowned sparrows (Zonotrichia leucophrys), and green-tailed towhees (Pipilo chlorurus) were captured most frequently. Rates of capture for residents, short-distance migrants, and Neotropical migrants were higher in arroyos than in adjacent shrubland and showed an increase after mid-April caused by an influx of Neotropical migrants heading north to their breeding grounds. Our results suggest that arroyos are important as stopover sites during spring for many migrants, especially Neotropical migrants, as they cross the northern Chihuahuan Desert. Utilizamos redes de niebla para muestrear aves residentes y migrantes en el habitat de matorrales de los cauces secos y de las mesetas adyacentes de la parte norte del desierto de Chihuahua durante finales de febrero hasta principios de mayo de los años 1993 a 1997. Capturamos 723 aves pertenecientes a 49 especies.La diversidad de las especies fue más grande en los cauces secos que en las mesetas adyacentes. Las especies capturadas con más frecuencia fueron los gorriones pecho negro (Amphispiza bilineata), gorriones de corona blanca (Zonotnchia leucophrys), y toquis cola verde (Pipilo chlorurus). Las tazas de captura para las aves residentes, los migrantes de una distancia corta, y los migrantes neotropicales fueron más altas en cauces secos comparadas al matorral adyacente y mostraron un aumento después de mediados de abril por causa de la llegada de migrantes neotropicales rumbo al norte a sus áreas de apareo. Nuestros resultados sugieren que los cauces secos son importantes como sitios de parada durante la primavera para muchas aves migrantes, en particular para los migrantes neotropicales, mientras pasan la región norteña del desierto de Chihuahua.
