Conservation

Conservation Restricted RangeBrandt's Cormorant populations are stable to declining. The Waterbird Conservation for the Americas estimates that there are 151,200 breeding birds on the continent, rate them a 15 out of 20 on the Continental Concern Score, and list them as a Species of High Concern. Legal protection from egging and hunting may have led to increases in populations from 1900 to 1970. They are not on the 2014 State of the Birds Watch List.Back to top
