Long-range migration of a chinstrap penguin from Bouvetøya to Montagu Island, South Sandwich Islands
Abstract We describe a long-range migration of a pre-moulting adult chinstrap penguin from Bouvetøya, a small relatively recently established colony, to the South Sandwich Islands, where large, established colonies of this species reside. The trip lasted around three weeks, covered ∼3600 km, and the...
