Management
| Threats The threats to which this taxon is subject. |
Egg loss and chick mortality is primarily due to adverse weather conditions and occasional predation by skuas. |
Taxon Biology
| Diet and Feeding Diet and feeding details |
Euphausiid shrimp, pteropods, cephalopods, fish and medusae form the basis of the Antarctic petrel's diet. They feed while swimming but can dive well from the surface and the air. |
| Habitat Includes realm (e.g. Terrestrial etc) and climatic information (e.g. Boreal); also includes requirements and tolerances; horizontal and vertical distribution; |
Antarctic petrels are found in open water with scattered ice bergs, ice floes and in open pack ice. They often nest on low snow-free cliffs exposed to wind. |
| Breeding biology Reproduction including mating habits, habitat usage in breeding, duration of breeding. |
One egg is laid in late November to early December each year. The incubation period lasts more than 45 days and chicks fledge from late February to mid-March. |
