This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

|Range Description:||The Antarctic Prion breeds on islands in the southern oceans, including the the Crozet Islands and Kerguelen Island (French Southern Territories), Macquarie Island and Heard Island (Australia), the Auckland Islands (New Zealand), South Georgia (Georgias del Sur ), the South Sandwich Islands (Islas Sandwich del Sur), Scott Island and the Scotia Archipelago. All birds leave the colonies after breeding, dispersing from pack ice in Antartica to as far north as Peru, and also occuring off South Africa and Australia1. |
