New Magellanic penguin Spheniscus magellanicus colony in a subantarctic island: good or bad news?

This paper provides data on a newly discovered colony for Magellanic penguin Spheniscus magellanicus in the southwest Atlantic Ocean. A new settlement for the species in the area was found while conducting southern rockhopper penguin Eudyptes chrysocome studies in the San Juan de Salvamento colony in Staten Island, Argentina. The newly established colony holds 88 breeding pairs. While the origin of the founders was not recognized, it is possible that individuals recently reached from the nearby Observatorio Island colony located ~ 20 km away. New colonies grant populations to expand and colonize new areas which holds promise in a climate change scenario. Nonetheless, this expansion might be in detriment of sibling species that already occupied the area.
