Mouvements en mer des puffins fouquets reproducteurs de la colonie de Gouaro Deva (Nouvelle- Calédonie) : compte rendu de mission, 25 février – 14 mars 2014

Abstract : We aimed at determining the feeding areas of wedge-tailed shearwaters from New Caledonia during the breeding season. Thirty eight active burrows were identified in the Temrock colony at Gouaro Deva. Forty-three adult individuals using these burrows were captured and fitted with a GPS logger. Thirty five GPS loggers were recovered from the birds returning to the colony, between one day and 13 days after birds had been fitted with it. GPS logs provided position data for a total of 45 trips, of which 35 were completely or near completely recorded. Trip duration ranged from one day to at least five days. Departure from the colony was systematically within the hour and half after sunrise. Return occurred all night long. The maximum distance to the colony during a trip ranged from 50 km to at least 898 km. Most of the movements of the birds occurred within an area of the ocean forming a rectangle parallel to the northwest coast of New Caledonia’s Grande Terre, about 300 km long and about 150 km seaward. The chicks were weighed at regular intervals throughout the experiment, to compare their growth with that of chicks from two other shearwater colonies in the Coral Sea. At the end of the experiment, 30 adults were fitted with light-sensitive loggers (GLS) in order to obtain information on bird movements outside the breeding season. These GLS loggers should be recovered in late November 2014, when the birds will return to the colony.
