This species has a very 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 is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to 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:||Phalacrocorax atriceps is found on the southern tip of South America, from central Chile round to central Argentina, and on the Falkland Islands (Islas Malvinas). Phalacrocorax (atriceps) bransfieldensis breeds on the Antarctic Peninsula and the South Shetland Islands. Phalacrocorax (atriceps) georgianus is found on the islands of South Georgia (Georgia del Sur), the South Orkney Islands, South Sandwich Islands (Islas Sandwich del Sur) and Shag Rocks (Scotia Sea). In the Indian Ocean, Phalacrocorax (atriceps) melanogenis occupies the Crozet Islands (French Southern Territories), Phalacrocorax (atriceps) nivalis is found on Heard Island (to Australia) and Phalacrocorax (atriceps) purpurascens is restricted to Macquarie Island (to Australia) (del Hoyo et al. 1992).|
