(Waterbird Society, 2005-03)
The foraging behavior and feeding locations of the Red-legged Cormorant (Phalacrocorax gaimardi) were studied at Ria Deseado, Argentina during the last week of the incubation period in 1999. VHF radio-transmitters were ...
Foraging Behavior and Feeding Locations of Imperial Cormorants and Rock Shags Breeding Sympatrically in Patagonia, Argentina
(Waterbird Society, 2003-12)
Although there have been several studies of the foraging behavior of the Imperial Cormorant (Phalacrocorax atriceps) and the Rock Shag (Phalacrocorax magellanicus), none document the feeding performance and the use of ...
Corrigendum to “Lousy chicks: Chewing lice from the imperial shag, Leucocarbo atriceps”
(Australian Society for Parasitology, 2018-08)
The authors regret an involuntary mistake in the specific determination of Pectinopygus turbinatus, where the correct name is Eidmanniella pellucida. As follow we present the revised taxonomic review for this species: ...
Evidences of Rock shags (Phalacrocorax magellanicus) and Imperial cormorants (Ph. atriceps) leaving their nest by night
(African Seabird Group, 2002-12)
Imperial Cormorants Phalacrocorax atriceps and Rock Shags P. magellanicus are foot-propelled pursuit divers usually described as visual feeders (Johnsgard 1993). Previous studies describing Imperial Cormorant and Rock Shag ...
Serosurvey for selected infectious agents in two sympatric species of cormorants (Phalacrocorax atriceps and Phalacrocorax magellanicus) from coastal Patagonia, Argentina
(Wildlife Disease Association, 2013-01)
We conducted a serologic survey for selected infectious agents on two sympatric cormorants, the Imperial Cormorant (Phalacrocorax atriceps) and the Rock Shag (Phalacrocorax magellanicus). Blood was collected from 267 ...
Dive depth and plumage air in wettable birds: the extraordinary case of the imperial cormorant
(Inter-Research, 2007-12)
Cormorants are considered to be remarkably efficient divers and hunters. In part, this is due to their wettable plumage with little associated air, which allows them to dive with fewer energetic costs associated with ...
Long-term population trends of the Red-legged Cormorant Phalacrocorax gaimardi on the Argentine coast
(Cambridge University Press, 2015-06)
The world population of Red-legged Cormorant Phalacrocorax gaimardi is reasonably small and has showed rapid declines. In Argentina, this species breeds in 13 localities and is considered as 'Endangered' by the national ...
Diet of the Neotropic Cormorant Phalacrocorax olivaceus at West Chubut, Patagonia, Argentina
(Waterbird Society, 2009-09)
A total of 124 pellets (regurgitated casts) produced by the Neotropic Cormorant (Phalacrocorax olivaceus) were collected monthly between January 2004 and November 2005 from a roosting site at Rosario Lake Chubut, Patagonia, ...
Induced Regurgitation Versus Stomach Sampling: Assessing Their Value for the Characterization of Imperial Cormorant (Phalacrocorax atriceps) Diet
(Waterbird Society, 2017-06)
Several studies have applied induced regurgitations to characterize the diet of cormorants, but none have presented quantitative information indicating complete stomach contents were obtained. Our goal was to test the value ...
