Dispersal and habitat preference of juvenile emperor penguins

Fisheries management

Antarctic ecosystem

This study tracked nine juvenile emperor penguins fitted with satellite transmitters at the Atka Bay colony in western Dronning Maud Land, Antarctica, during the austral summer of 2016/2017. The fledglings migrated northward over 1,800 km to the northern extents of CCAMLR subareas 48.4 and 48.6, reaching as far as 52° S and spanning 63° of longitude. After a brief period at their northernmost positions, all individuals made a synchronous southward return to the marginal ice zone (MIZ) between mid-April and mid-May. The MIZ appears to represent critical feeding habitat for juvenile emperor penguins. The study found that current and proposed marine protected areas (MPAs) in the Southern Ocean do not adequately cover the MIZ year-round, and that juvenile penguins were excluded from the proposed Weddell Sea MPA for over four months. The authors recommend dynamic, spatio-temporal management approaches to better protect these young penguins during their vulnerable first trip to sea.
