Population justification:

Convey et al. (1999) estimate a world population of ~4 million breeding pairs.

Trend justification: The species expanded its range and its population in the mid-20th century, potentially owing to increased prey (krill) availability (del Hoyo et al. 1992). It is currently decreasing at most sites on the Antarctic Peninsula, except at the southern extreme of its range where it is increasing. It is stable at South Sandwich Island (Lynch et al. 2016). The population trend is unknown at many other locations.
