Abstract (en):
We identified 83 species of birds in the flooded savannas of Meta and Casanare (Colombia) states during July and November 2012 and March and April 2013. We added four species to the checklist of birds of the Colombian Orinoco Basin. In both the rainy and dry seasons, wading birds had the largest number of species and individuals. Most species congregated and bred during the rainy season and abundance of aquatic birds varied according to the season. We also identified six sites that harbored the largest concentration of Neochen jubata (Orinoco Goose), Mycteria americana (Wood Stork), Phimosus infuscatus (Bare-Faced Ibis), Eudocimus ruber (Scarlet Ibis) and Phaetusa simplex (Large-billed Tern) in Colombia.
Abstract (es):
En las sabanas inundables de los departamentos del Meta y Casanare (SIMC), Colombia, se identificaron 83 especies de aves acuáticas durante los meses de julio y noviembre de 2012 y marzo y abril de 2013. Cuatro especies fueron adicionadas a la lista de aves de la cuenca del Orinoco colombiano. Tanto en época lluviosa como seca, el grupo de aves vadeadoras presentó el mayor número de especies e individuos. Una de las principales características de las aves acuáticas de las SIMC es la de ser en su mayoría gregarias. La mayoría de estas aves se reproducen en la época lluviosa y existe variación de la abundancia de acuerdo con el periodo climático. También se identificaron seis áreas de alta concentración de individuos, algunas de las cuales albergan las mayores densidades de poblaciones en Colombia de Neochen jubata (pato carreterro), Mycteria americana (cabeza de hueso), Phimosus infuscatus (coquito), Eudocimus ruber (corocora) y Phaetusa simplex (gaviotín picudo).
