Conservation

Conservation Low ConcernIn the 1960s, Neotropic Cormorant populations declined severely in Texas; since then, these populations have shown a general trend toward growth. The cause of the declines is not conclusively understood. The North American Waterbird Conservation Plan estimates 16,000 breeding birds in North America, rates the species a 12 out of 20 on the Continental Concern Score, and lists it as a Species of Moderate Concern. Neotropic Cormorant is not listed on the 2014 State of the Birds Report. Back to top
