Geographical variation in egg size dimorphism in rockhopper penguins
(Springer, 2010-04)
All crested penguins present a unique reversed hatching asynchrony: the larger second-laid egg (B-egg) hatches before the smaller first-laid egg (A-egg). Although both eggs often hatch, the A-chick generally dies of ...
New records of South American sea lion Otaria flavescens predation on southern rockhopper penguins Eudyptes chrysocome at Staten Island, Argentina
(Springer, 2012-02)
Predation by fur seals and sea lions has been identified, among others, as a potential cause of the declines in rockhopper penguin populations. Here, we report a multiple predation event of southern rockhopper penguins ...
Diving patterns of breeding female rockhopper penguins (Eudyptes chrysocome): Noir Island, Chile
(Springer, 2009-12)
The diving behaviour of female southern rockhopper penguins (Eudyptes chrysocome) was studied at Noir Island (54°30′S-73°00′W), Chile, in the southeast Pacific Ocean. This isolated island is located at the edge of the ...
Avian Predation at a Southern Rockhopper Penguin colony on Staten Island, Argentina
(Springer, 2008-12)
We studied predation risk in relation to nest location and subcolony size in Southern Rockhopper Penguins (Eudyptes chrysocome chrysocome) during the chick-rearing period. Striated Caracaras (Phalcoboenus australis), the ...
Taxonomy based on limited genomic markers may underestimate species diversity of rockhopper penguins and threaten their conservation
(Wiley, 2021)
Aim Delimiting recently diverged species is challenging. During speciation, genetic differentiation may be distributed unevenly across the genome, as different genomic regions can be subject to different selective pressures ...

Population trends of the Southern Rockhopper Penguin (Eudyptes chrysocome chrysocome) at the northern limit of its breeding range: Isla Pingüino, Santa Cruz, Argentina
(Springer, 2016-08)
During the last century, there has been a steady decline in the global breeding population of Eudyptes chrysocome chrysocome, and this species has been exposed to many different threats. However, the small breeding population ...
Effect of oceanographic conditions on the winter dispersion of Eudyptes chrysocome chrysocome
(Inter-Research, 2007-12)
We used Argos satellite transmitters to monitor the movement and oceanographic habitats used by rockhopper penguins Eudyptes chrysocome chrysocome during their winter dispersal from Staten Island, Argentina, for 2002 (n = ...
