Cleptoparasitismo intra e interespecífico en una colonia mixta de gaviotines Real (Sterna maxima) y Pico Amarillo (S. eurygnatha)

Mostrar todas las versiones(3)

Within seabirds, terns are frequently affected by foodrobbing. We document the occurrence of kleptoparasitism at a mixed-species colony ofRoyal (Sterna maxima) and Cayenne (S. eurygnatha) terns at Punta León, Chubut. In two seasons we observed both inter- and intra-specific food robbing by adult ter...
