Species- and sex-specific differences in foraging behaviour and foraging zones in blue-footed and brown boobies in the Gulfo of California
(Marine Ecology Progress Series, 2009)
When two closely related species, with each species presenting strong sex specific differences in size, coexist resource partitioning can be expected. We studied the sex specific foraging behaviour of two sympatric seabird ...
Do penguins share? Evidence of foraging niche segregation between but not within two sympatric, central-place foragers
(Inter-Research, 2016-04)
Niche theory predicts that sympatric species should differentiate ecologically in order to co-exist and conspecifics will also differentiate to reduce intra-specific competition. As central-place foragers, colonial breeding ...
Flexibilidad del comportamiento de forrajeo del cormorán guanay (Phalacrocorax bougainvillii) bajo un ambiente marino impredecible
(Universidad Peruana Cayetano HerediaPE, 2022)
El Sistema Norte de la Corriente de Humboldt es altamente productivo, pero impredecible. Las aves marinas endémicas en esta región, las cuales evolucionaron bajo condiciones ambientales cambiantes, exhiben estrategias ...
Prey Search Behavior of the Imperial Cormorant (Phalacrocorax atriceps) during the breeding season at Punta León, Argentina
(Waterbird Society, 2012-05)
Behavior by a foraging seabird during the breeding season can be examined by analyzing time invested throughout the foraging route to determine the presence of Area-Restricted Search (ARS) as well as other characteristics ...
Insights into diet and foraging behavior of imperial shags (Phalacrocorax atriceps) breeding at Staten and Becasses Islands, Tierra Del Fuego, Argentina
(Wilson Ornithological Society, 2016-12)
Diet and behavior are essential aspects of ecological studies, and are even more informative if both aspects are studied together. We collected samples of feathers (n = 10 of unknown sex at Becasses Island in 2013) and of ...
High-coverage genomes to elucidate the evolution of penguins
(Oxford University Press, 2019-09)
Background: Penguins (Sphenisciformes) are a remarkable order of flightless wing-propelled diving seabirds distributed widely across the southern hemisphere. They share a volant common ancestor with Procellariiformes close ...
Differences in diet composition and foraging patterns between sexes of the Magellanic penguin (Spheniscus magellanicus) during the non-breeding period as revealed by δ13C and δ15N values in feathers and bone
(Springer, 2014-03)
In diving seabirds, sexual dimorphism in size often results in sex-related differences of foraging patterns. Previous research on Magellanic penguins, conducted during the breeding season, failed to reveal consistent ...
Comportamiento de alimentación del pingüino penacho amarillo del sur Eudyptes chrysocome y del pingüino de Magallanes Spheniscus magellanicus en Isla de los Estados, Tierra del Fuego, ArgentinaForaging behavior of southern rockhopper penguin Eudyptes chrysocome and Magellanic penguin Spheniscus magellanicus at Isla de los Estados, Tierra del Fuego, Argentina
(2016-08-22)
El comportamiento de alimentación y dieta de las aves marinas, engeneral, varía con la localidad, el sexo y el estadio del ciclo anual. Además, en una misma región pueden alimentarse distintas especies con requerimientos ...
