Hematology, Biochemistry and Serum Protein Analyses of Antarctic and non-Antarctic Skuas
(Waterbird Society, 2015-06)
Determination of hematological and biochemical parameters provides important data to assess the physiological condition in wild birds. Therefore, to carry out ecophysiology or conservation studies it is essential to establish ...
Diet of the Brown Skua (Stercorarius antarcticus lonnbergi) at Hope Bay, Antarctic Peninsula: differences between breeders and non-breeders
(Springer, 2019-02)
Top predators exhibit a critical role in ecosystem functioning and in the stability of the food web, so research on diet is relevant to understand their foraging behavior. Seasonal variation in diet and prey selection may ...
Diet of South Polar Skua chicks in two areas of sympatry with Brown Skua
(Waterbird Society, 2011-12)
The food provided to South Polar Skuas (Stercorarius maccormicki) chicks was determined at two Antarctic sites where South Polar Skuas breed sympatrically with Brown Skuas (S. antarcticus). At Harmony Point on Nelson Island, ...
Declining health status of Brown Skua (Stercorarius antarcticus lonnbergi) parents and their offspring during chick development
(Springer, 2018-01)
During breeding, Brown Skuas (Stercorarius antarcticus lonnbergi) perform a great physical effort in the care and maintenance of the nest. Interestingly, the breeding colony on which this work was conducted is in steady ...
Trophic interactions between brown and south polar skuas at Deception Island, Antarctica
(Springer, 2012-02)
It is broadly accepted that the brown skua (Stercorarius antarcticus lonnbergi) competitively excludes the south polar skua (S. maccormicki) from penguin colonies when breeding sympatrically, forcing the latter to feed on ...
