Abstract (en):
Nesting colonies represent key areas for the reproduction of the most characteristic and abundant waterbirds
from the Colombian and Venezuelan flooded Llanos. During the rainy season of 2012 and the onset of the
2013 dry season, I located a colony in a ranch called Las Cadenas, located in the Casanare department. Eleven
species were observed nesting, which places it as the most diverse of those described to date in the region of the Llanos. According to the owners of the property on which sits the colony, birds begin to nest with the arrival of rainfalls in April and leave the colony in November. Compared to other colonies described for the Colombian and Venezuelan Llanos and given its size (6,3 has) and the estimated number of nests, around 500, this colony can be considered small.
Abstract (es):
Las garceros constituyen áreas clave para la reproducción de las aves acuáticas más características y abundantes de los Llanos inundables de la Orinoquia. Durante la estación de lluvias de 2012 y el inicio de la estación seca de 2013, se localizó un garcero en la finca de Las Cadenas, ubicada en el departamento de Casanare, en el que se observaron 11 especies anidando, lo que lo sitúa como el más diverso de los descritos hasta la fecha en la región de los Llanos colombianos. Según la información aportada por los propietarios, las aves comienzan a anidar con la llegada de las precipitaciones en abril, y abandonan el garcero en noviembre. Con base en el área que ocupa el garcero (6,3 ha), y el número de nidos, estimado en unos 500, este garcero puede considerarse pequeño en relación a otros descritos para los Llanos colombo-venezolanos.
