Resumen
WE DESCRIBE FOUR METHODS TO CAPTURE KELP GULLS (LARUS DOMINICANUS) AND ESTIMATEDITS EFFICIENCY IN TALCAHUANO, CHILE. THE FOUR METHODS WERE: (I) HAND-NET, (II) SLIDING BOW LASSO,(III) PLIABLE ARCH, AND (IV) ADAPTED BAL-CHATRI. THE MOST SUCCESSFUL METHOD WAS THE ADAPTEDBAL-CHATRI FOLLOWED BY THE SLIDING BOW LASSO. THE HAND-NET AND THE PLIABLE ARCH WERE THE LEASTEFFICIENT METHODS. THE EFFICIENCY OF THESE METHODS DIMINISHED AFTER THE FIRST CAPTURE SEEMINGLYDUE TO RAPID LEARNING BY THE GULLS. WE ALSO COMMENT ON THE GULL?S BEHAVIORAL DISPLAYS DURINGCAPTURE EVENTS.
