| dc.description.abstract | Laguna de Sayula, a seasonal freshwater wetland in Jalisco, western Mexico, supports many resident and migratory bird species, particularly during the dry season (October to May). We documented changes in habitat condition (i.e., water vs. mudflat vs. land cover) and occurrences of 12 waterbird species during the dry season. From October to February, much of the lagoon was covered with water and mudflats, and the avifauna was dominated by resident killdeer (Charadrius vociferus) and migratory long-billed curlew (Numenius americanus). Between March and May, there was significantly less area covered by water and mudflats, and killdeer and the migratory spotted sandpiper (Actitis macularia) were most common. Species tended to co-occur in plots, often in large numbers, suggesting that they were tracking patchy resources within the study area. = La Laguna de Sayula, una cuenca endorreica estacional ubicada en Jalisco, en el occidente de México apoya muchas especies de aves residentes y migratorias, particularmente durante la estación seca (octubre a mayo) Documentamos los cambios en las condiciones del hábitat (i.e., agua vs. lodazal vs. cobertura del suelo) y la presencia de 12 especies de aves acuáticas durante la estación seca. De octubre a febrero, en su mayoría la laguna estuvo cubierta por zonas acuáticas y lodosas, y las aves dominantes fueron el chorlito tildío (Charadrius vociferus; residente) y el zarapito piquilargo (Numenius americanus; migratorio). Entre marzo y mayo, se presentó una cobertura de agua y lodo significativamente menor, y el chorlito tildío y el playero alzacolita (Actitis macularia; migratorio) fueron los más comunes. Varias especies ocurrieron en los mismos sitios, frecuentemente en grandes cantidades, lo cual sugiere que seguían los parches de recursos dentro del área de estudio. | |
