          Abstract

          Los humedales costeros son ecosistemas que tienen una alta diversidad biológica. No obstante, en Chile existe una carencia de estudios sobre la estructura y dinámica de las comunidades de aves que los habitan. Para investigar la importancia del humedal del río Mataquito como hábitat de aves acuáticas se realizaron censos estacionales entre 2006 y 2010. Se estudió la diversidad de aves acuáticas, se caracterizó la estructura temporal del ensamble y se identificó a las especies que caracterizan el patrón temporal de la estructura comunitaria a través de un Análisis de Especies Indicadoras (IndVal). Se registró un total de 54 especies de aves pertenecientes a 18 familias, las que representan un 41% del total de especies de aves acuáticas de Chile. El 81% fueron residentes, el 17% visitantes y el 2% esporádicas. Larus pipixcan, Rynchops niger, Pelecanus occidentalis, Thalasseus elegans, Larus modestus y Haematopus palliatus fueron las especies más abundantes. La estructura del ensamble de aves no presentó un patrón temporal definido. El Análisis de Especies Indicadoras mostró que Rynchops niger, Egretta alba, Egretta thula, Anas georgica y Thalasseus elegans caracterizaron significativamente los períodos de verano-otoño. Debido a su gran riqueza de especies, este humedal cumple un rol importante como hábitat de aves acuáticas tanto residentes como migratorias.

          Temporal variability in the abundance and diversity of birds in the Mataquito River wetland, Región del Maule, Chile Coastal wetlands support high biological diversity. However, in Chile there is a lack of information in terms of the structure and dynamics of bird assemblages in this kind of ecosystems. To investigate the importance of the Mataquito River wetland for waterbirds, we conducted seasonal censuses between 2006 and 2010. We evaluated waterbird diversity, characterized the temporal pattern of the assemblage and used an Indicator Species Analysis (IndVal) to identify those bird species that characterize the temporal pattern of the assemblage structure. We recorded 54 bird species belonging to 18 families, which represent 41% of the Chilean waterbird species. The 81% of the species were resident, 17% were visitant, and 2% were sporadic. Larus pipixcan, Rynchops niger, Pelecanus occidentalis, Thalasseus elegans, Larus modestus and Haematopus palliatus were the most abundant species. The assemblage structure did not show a clear temporal pattern. Indicator Species Analysis showed that Rynchops niger, Egretta alba, Egretta thula, Anas georgica and Thalasseus elegans characterized the summer-autumn period. Due to its high species richness, this wetland has an important role for migrant and resident waterbird species.
