Species richness and density of seabirds in Isla del Coco bays, Costa Rica, related to the occurrence of breeding colonies
(2016-10-15)
Isla del Coco is one of the five oceanic islands situated on the eastern tropical Pacific Ocean and represents an important nesting and roosting site for seabirds. Despite several factors that can potentially impact its ...
New sightings records of marine mammals and seabirds off French Guiana

Skuas (Stercorarius spp.) moult body feathers during both the breeding and inter-breeding periods: implications for stable isotope investigations in seabirds
(Wiley Blackwell Publishing, Inc, 2017-04)
Seabirds are mostly thought to moult during the inter-breeding period and the isotopic values of their feathers are often therefore assumed to relate to their assimilated diet during such periods. We observed Brown Skuas ...
Intraspecific variability in isotopic composition of a monomorphic seabird, the Common Tern ( Sterna hirundo ), at wintering grounds
(Csiro Publishing, 2019-04)
Understanding sex differences in foraging behaviour has important implications for breeding biology and population ecology. This requires the evaluation of segregation throughout the annual cycle, including the non-breeding ...
First evidence of anthropogenic debris in nests of the Kelp Gull (Larus dominicanus) from a small semi-desert Argentinean coastal ecosystem
(Pergamon-Elsevier Science Ltd, 2021-09)
Here, we present the first findings of anthropogenic debris (AD) used as nest material by the Kelp Gull (Larus dominicanus) on a small semi-desert coastal ecosystem in northern Argentine Patagonia. Anthropogenic debris was ...
Differential predation by mammals and birds: Implications for egg-colour polymorphism in a nomadic breeding seabird
(Oxford University Press, 2002-02)
Selection for crypsis in varying environments has long been established as the main evolutionary force promoting the huge variation in avian egg coloration. In several avian species, variation in egg coloration exists, but ...
Post-moult movements of sympatrically breeding Humboldt and Magellanic Penguins in south-central Chile
(Elsevier, 2016-07)
Ten Humboldt (Spheniscus humboldti) and eight Magellanic Penguins (S. magellanicus) were successfully equipped with satellite transmitters in March 2009 on Islotes Puñihuil in central south-Chile to follow their post-moult ...

Spatial overlap between foraging seabirds and trawl fisheries: Implications for the effectiveness of a marine protected area at Golfo San Jorge, Argentina
(Cambridge University Press, 2010-09)
La evaluación de las actividades humanas y la comprensión de su interacción con las aves marinas son importantes para la elaboración adecuada de esquemas de planificación para la conservación. Se analizó el uso espacial ...
