The Southern rockhopper penguin (Eudyptes chrysocome) is a highly charismatic species of the Southwestern Atlantic, primarily breeding on subantarctic islands. The northernmost colonies are found in Argentina, on Isla Pingüino in Santa Cruz, and on Isla de los Estados, in Bahía Franklin and San Juan de Salvamento. This penguin is an excellent swimmer, feeding mainly on krill and small fish. In Argentina, it is listed as “Endangered” (MAyDS and AA, 2017), with one of the main threats being climate change, as the species is highly sensitive to environmental fluctuations. Globally, it is categorized as “Vulnerable” (BirdLife International, 2020).
