Justification: 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 increasing, 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: | This species is solely marine and is mostly found in zones with light ice pack. Its diet is comprised almost exclusively of Antarctic krill, but it will also take fish and other species of crustaceans when possible. Prey capture is apparently by pursuit-diving up to a depth of 70 m, but mostly less than 45 m. It breeds on irregular rocky coasts in ice free areas, forming large colonies of hundreds and thousands of birds and beginning laying in November at the earliest1. |
