Resumen:
We observed adult Kelp Gulls (Larus dominicanus) capture and eat Olrogs Gull (L. atlanticus) chicks in the Bahía Blanca estuary, Argentina. This estuary holds the largest breeding colony of Olrogs Gulls. There are no previously published reports of Kelp Gulls capturing and eating Olrogs Gull chicks. Our data supports suggestions made by other authors about the possible existence of conflicts in colonies where both species breed in close proximity.
