Abstract: | We studied the predation of the Western Gull (Larus occidentalis) on the Eared Grebe (Podiceps nigricollis) from December 2002 to June 2003 at a solar saltworks. Mechanisms of predatory behavior, such as use of perching site, attack maneuvers and killing and catching grebes, as well as behavior of the grebes as a response to the presence and attacks by gulls, were recorded. In all 35 cases where a gull attempt to feed was seen, it was successful in every case. This is the first report about predation by the Western Gull on the Eared Grebe. |
