Erect-crested penguin (Eudyptes sclateri) & Eastern Rockhopper penguin (Eudypes filholi) colony boundaries on the Antipodes Islands, New Zealand (2024)

GeoJSON polygons and orthomosaics delineating the boundaries of Erect-crested penguin (Eudyptes sclateri) and Eastern Rockhopper penguin (Eudypes filholi) breeding colonies surveyed on the Antipodes Islands, New Zealand, during October-December 2024. Colony boundaries were derived from 90th percentile kernel density contours of individual penguin locations mapped from drone survey orthomosaics. Data were collected as part of a comprehensive population assessment of the entire global range of the species.
