Agustina Gomez-Laich, Auteur ; Carolina Pantano, Auteur ; Rory P. Wilson, Auteur ; Walter S. Svagelj, Auteur ; Ken Yoda, Auteur ; Richard Gunner, Auteur ; Flavio Quintana, AuteurLeg rings are frequently used to mark aquatic birds in order to identify individuals, and study population dynamics and migration patterns, with the proviso being that the rings should not affect the birds. The effects of tags and rings are of p[...]
Article
Walter S. Svagelj, Auteur ; Agustina Gomez-Laich, Auteur ; María Rita Pérez, Auteur ; Gustavo M. Somoza, Auteur ; Flavio Quintana, AuteurThe environment experienced during development is a key factor determining intraspecific variation in postnatal growth. In sexually size-dimorphic species, the larger sex typically grows at a higher absolute rate and consequently is more sensiti[...]
Article
Agustina Gomez-Laich, Auteur ; Ken Yoda, Auteur ; Flavio Quintana, AuteurBetween 25-30 November 2013, 2014 and 2015, miniaturized video cameras were attached to Magellanic Penguins (Spheniscus magellanicus; n = 14) in Punta Norte/San Lorenzo, Peninsula Valdes, Chubut, Argentina. The objective was to examine prey sele[...]

Marcela M. Uhart, Auteur ; Luciana Gallo, Auteur ; Flavio Quintana, AuteurAlbatrosses (Diomedeidae) and large petrels (Macronectes and Procellaria spp.) are among the world’s most rapidly declining birds. Some of the most endangered species, Amsterdam Albatross Diomedea amsterdamensis, Indian Yellow-nosed Albatross Th[...]

María Soledad Leonardi, Auteur ; Walter S. Svagelj, Auteur ; Agustina Gómez Laich, Auteur ; Flavio Quintana, AuteurPrevious studies on vertical transmission of lice on terrestrial birds have shown that the intensity of parasitism can vary within broods in relation to the hatching order of chicks. In species where the hatching order has an important effect on[...]

Article
Luciana Gallo, Auteur ; Flavio Quintana, Auteur ; Walter S. Svagelj, Auteur ; Marcela Uhart, AuteurAbstract. Plasma biochemistries provide a complementary method for assessing physiological and nutritional status of free-ranging wild birds. Triglycerides, total protein and alkaline phosphatase were determined in 110 free-living Imperial Cormo[...]
Article
Walter S. Svagelj, Auteur ; Flavio Quintana, AuteurAbstract. Cormorants and shags (Phalacrocoracidae) are sexually monomorphic in plumage but dimorphic in size with males larger and heavier than females. Such size dimorphism has been capitalized upon for several species in the family to sex adul[...]
Article
Alexandra Sapoznikow, Auteur ; Flavio Quintana, AuteurThe rock shag (Phalacrocorax magellanicus) is an endemic species from southern Argentina and Chile. In Argentina, the population is distributed along the Patagonian coast in 143 small colonies (5-377 pairs). We studied colony and nest site fidel[...]
Article
Juan E. Sala, Auteur ; Rory P. Wilson, Auteur ; Esteban Frere, Auteur ; Flavio Quintana, AuteurSeabirds have to deal with environmental variability and are predicted to modulate foraging behavior to maximize fitness, with particularly strong selection pressure for optimal behavior during chick provisioning when energy demands are high. We[...]
Article
Esteban Frere, Auteur ; Flavio Quintana, Auteur ; Patricia Gandini, Auteur ; Rory P. Wilson, AuteurRadiotelemetry was used to assess the distribution and diving behaviour of Rock Shags Phalacrocorax magellanicus and Red-legged Cormorants Phalacrocorax gaimardi breeding in sympatry, and Rock Shags breeding in isolation. When breeding in sympat[...]
Article
Luciano Calderon, Auteur ; Walter S. Svagelj, Auteur ; Flavio Quintana, Auteur ; Stephen C. Lougheed, Auteur ; Pablo L. Tubaro, AuteurIn long-lived birds with significant paternal care contribution, as the case of seabirds, extra-pair paternity (EPP) is an infrequent phenomenon. Intriguingly, and in contrast to the general pattern exhibited by seabirds, EPP rates appear relati[...]
Article
Pablo Yorio, Auteur ; Flavio Quintana, Auteur ; Patricia Dell'Arciprete, Auteur ; Diego Gonzalez-Zevallos, AuteurAssessing human activities and understanding their interaction with seabirds constitute important steps in the development of adequate conservation planning schemes. We evaluated the spatial use of the marine environment by foraging Magellanic P[...]
Article
Sabrina Harris, Auteur ; Andrea Raya Rey, Auteur ; Carlos Zavalaga, Auteur ; Flavio Quintana, AuteurIndividual consistency in foraging behaviour can generate behavioural variability within populations and may, ultimately, lead to species diversification. However, individual-based long-term behavioural studies are particularly scarce in seabird[...]
