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). The population trend appears to be stable, and hence the species does not 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.

Habitat and Ecology [top]

Habitat and Ecology: The Antarctic Petrel nests on snow-free cliffs and rock faces. Nesting sites are mostly coastal or on offshore islands, but it has been found to nest up to 250 km inland. The diet of this species is comprised mostly of krill, but also fish and squid. Prey is obtained mostly by surface-seizing but diving from the air and surface is also seen (del Hoyo et al. 1992).
