Breeding success of Northern Rockhopper Penguins (Eudyptes moseleyi) at Gough Island, South Atlantic Ocean

Northern Rockhopper Penguins (Eudyptes moseleyi) on Gough Island exhibit breeding success strongly linked to the density of nests and the birds' response to threats. While brood loss peaks during incubation (33–61%), most hatchlings (71%) survive to form crèches, with 73% molting into juvenile plumage. The study found that higher nest densities within a 1.5-meter radius and proactive threat responses by breeding birds significantly improve survival rates, highlighting critical factors for this declining species. Researchers tracked brood loss and analyzed behavioral and environmental influences on breeding success, providing insights into conservation strategies for one of the world's most vulnerable penguin populations.
