Taxonomic note
Following Kennedy and Spencer (2014) the genus Phalacrocorax has been divided into six genera, with P. magellanicus, P. bougainvilliorum, P. atriceps, P. verrucosus, P. carunculatus, P. chalconotus, P. onslowi, P. campbelli, P. ranfurlyi and P. colensoi moved into Leucocarbo (HBW and BirdLife International 2018). Phalacrocorax bougainvilliorum (del Hoyo and Collar 2014) was previously listed as P. bougainvillii.

Population justification: Zavalaga and Paredes (1999) estimated the population at 3.7 million individuals, hence the population is best placed in the band 2,500,000-4,999,999 individuals.
Trend justification: The species has fluctuated in numbers in the past, but overall declines in the region of 20-29% are suspected in the past three generations (33 years).
