Population status

Pelagic Cormorant
(Phalacrocorax pelagicus)

Pelagic Cormorants are not very faithful to colony sites, so monitoring of selected colonies is not a good way to track the population: instead periodic surveys of all known colonies are required, but few of these are available for Canada. Declines in breeding populations were observed in the Strait of Georgia, British-Columbia, between 1987and 2000 (Chatwin et al. 2002 in Hobson 2013). However, current data from the Christmas Bird Count for North America suggest that the population has changed little since 1970. These results likely reflect the population in Canada, but better information on Canadian breeding colonies is desirable.
