Abstract

The feeding ecology of Gallinula chloropus galeata was studied collecting seasonal samples (spring, summer and winter). Twenty eight stomachs were analyzed. In each one the volume of each taxonomic entity was registered. The Weighted Resultant Index (Mohan and Sankaran 1988) and Seasonal amplitude of the niche (Levins 1968) were calculated. This study revealed for Gallinula chloropus galeata an opportunistic behavior. The trophic breath of the niche did not show seasonal variations.
