Conservation

Conservation Low ConcernPelagic Cormorant appear to have declined between 1966 and 2014, according to the North American Breeding Bird Survey. The North American Waterbird Conservation Plan estimates a population of less than 69,000 breeding birds, lists it as a Species of High Concern, and rates it a 14 out of 20 on the Continental Concern Score. Pelagic Cormorant is not on the 2014 State of the Birds Watch List. Populations were reduced by human and natural disturbances from 1850 to 1900s. Back to top
