As every year for the last 12 years, a study plot of 280 nests of Black-Browed Albatrosses Thalassarche melanophris has been monitored on New Island, Falkland Islands (Islas Malvinas)*. This season the “Albatross Dream Team” consisted of Letizia Campioni, Deborah Pardo and Paulo Catry.

Individual presence, breeding success and laying dates were recorded to construct a solid demographic data set. At the same time, the main goals for this season were to deploy GPS and GLS trackers on breeding birds so as to record movements and activity during both incubation and chick-rearing. This tracking information will be used in conjunction with isotopic analyses of blood and feathers.

In addition, a large part of the project was to improve knowledge of the at-sea movements of pre-breeding immature birds. Seventy-five GPS trackers were deployed on three- to seven year-old birds previously banded as chicks that had returned as non-breeding “loafers” within the colony. These immatures were marked with TESA tape on their metal bands to aid in their identification for recapture. Again blood samples were taken for isotopic analyses as well as for genetic sexing. GLS loggers were then deployed for studying their wintering areas and we hope to recover them in the following years.
