Abstract We surveyed the coast of Chile between Isla Terhalten (54° 20′ S) and Islote Leonard (55°  44′ S) by boat during November–December 2005 to document breeding locations of Rockhopper (Eudyptes chrysocome chrysocome) and Macaroni (E. chrysolophus) penguins, and to count the number of nests during the early incubation period. A yacht-based observation recorded 1,000 Rockhopper Penguin nests at Isla Terhalten. Ground-based counts at Isla Noir estimated a total of 158,200 Rockhopper and 3… 

Foraging ranges in Southern Rockhopper Penguins (Eudyptes chrysocome chrysocome) on Isla Noir, Chile

The Southern Rockhopper Penguin, Eudyptes c. chrysocome, breeds on the Falkland/Malvina Islands, Isla Pingüino, and Ilsa de los Estados in the Atlantic Ocean and on Barnevelt, Terhalten,

BREEDING PHENOLOGY OF ROCKHOPPER PENGUIN Eudyptes chrysocome (SPHENISCIDAE) BY CAMERA MONITORING ON ISLA NOIR, CHILE: Breeding phenology of rockhopper penguin Eudyptes chrysocome (Spheniscidae) by camera monitoring on isla Noir, Chile

The reproductive phenology in penguin taxa may differ between colonies due to latitudinal and environmental effects as reported in early studies (Gwynn, 1953; Murphy, 1936; Warham, 1972), and the

Significant decline of endangered Antipodes Island penguins: Is extreme weather an additional impact?

Worldwide, most crested penguin species (Eudyptes spp.) are in decline. New Zealand's subantarctic Antipodes Islands are of international significance for erect‐crested (Eudyptes sclateri) and

Diving patterns of breeding female rockhopper penguins (Eudyptes chrysocome): Noir Island, Chile

It is confirmed that the diving behaviour of rockhopper penguins varies as a function of the physical and biological characteristics of the foraging areas and of the particular stage of the breeding season.

The Evolution of Seabirds in the Humboldt Current: New Clues from the Pliocene of Central Chile

The Horcon fossils suggest the existence of a mixed avifauna in central Chile during the Pliocene in concordance with the latitudinal thermal gradient, which resembles the current assemblages from the transitional zone.

Potential for redistribution of post‐moult habitat for Eudyptes penguins in the Southern Ocean under future climate conditions

Anthropogenic climate change is resulting in spatial redistributions of many species. We assessed the potential effects of climate change on an abundant and widely distributed group of diving birds,

Observaciones sobre el pingüino de penacho amarillo Eudyptes c. chrysocome en isla Gonzalo, archipiélago Diego Ramírez, Chile

The globally population decline of Southern Rockhopper penguins does considered this species as v ulnerable. However, in the Diego Ramirez archipelago (southern Chile) during the recent years the

Site-specific reproductive failure and decline of a population of the Endangered yellow-eyed penguin: a case for foraging habitat quality

Feral house cats Felis catus are potential predators of Endangered yellow-eyed penguins Megadyptes antipodes and were considered the principal causal factor in the species' decline on Stewart Island/Rakiura, New Zealand but predation by cats was not considered.

Estimates of Southern Rockhopper and Macaroni Penguin Numbers at the Ildefonso and Diego Ramírez Archipelagos, Chile, Using Quadrat and Distance-sampling Techniques

Abstract Populations of Southern Rockhopper (Euduptes chrysocome chrysocome) and Macaroni (E. chrysolophus) Penguins at key breeding sites in the Southern Hemisphere have declined substantially in

The distribution and abundance of Antarctic and Subantarctic penguins

This report provides the second comprehensive summary of the global distribution and abundance of Antarctic and Subantarctic penguins. It replaces the previous treatment by Wilson (BIOMASS Scientific

Population of the Macaroni Penguin Eudyptes Chrysolophus at Marion Island, 1994/95–2002/03, with Information on Breeding and Diet

There is indication that numbers of macaroni penguins Eudyptes chrysolophus at subantarctic Marion Island have decreased since the early 1980s, but error on estimates of abundance at these colonies precludes demonstration of a significant decrease in the overall population.

Re-evaluation of Historical Rockhopper Penguin Population Data in the Falkland Islands

Re-calculations of historical Rockhopper Penguin population trends in the Falkland Islands have important implications for the assessment of the global population size and long-term trends of this species.

Status and Numerical Trends of King, Gentoo, and Rockhopper Penguins Breeding in the Falkland Islands

The number of King Penguin chicks decreased by 19% from 339 to 275, which is probably a reflection of variable breeding success, rather than a decline in breeding pairs.

Penguins of the Magellan region

A review of the breeding populations of penguins within the Magellan region was conducted during the last five years, which included population censuses of all the surface breeding species throughout the Falkland Islands and southern South America.

Are penguins and seals in competition for Antarctic krill at South Georgia?

The hypothesis that the increased fur seal population at South Georgia may have resulted in greater competition for the prey of macaroni penguins, leading to the decline in their population is tested.

The spatial relationships between migratory parulid warblers and their ecological counterparts in the neotropics, p. 109-130, shows how the distribution and habits of these birds have changed over time.

Significant changes in plant communities in seabird colonies appear to result mainly from altered soil nutrient concentrations and pH, increased physical disturbance, and seed dispersal by seabirds and humans, however, few studies have rigorously studied the relative importance of these alterations.
