Natural recolonisation of sub-Antarctic Marion Island by Common Diving Petrels Pelecanoides urinatrix
Nocturnal burrow-nesting seabirds are notoriously difficult to study and can go unnoticed for years in remote areas. One of these species is the Common Diving Petrel Pelecanoides urinatrix, which has a circumpolar breeding distribution in the Southern Ocean, including at the sub-Antarctic Prince Edw...
