Resumen:
Two different types of food samples from the Black Skimmer were collected during the nonbreeding season. These two samples were analyzed and differed in the number of taxonomic categories presentes, the number of fish prey species found and the estimated size of fish prey. Given that collecting pellets involves little effort and low disturbance to the birds, the value of the analysis of pellets to monitor long-term dietary changes in Black Skimmers and other seabird species of similar size and diet is considerable. Correction factors are proposed to overcome underestimation of size and mass of fish prey remains found in pellets.
