The proposed division into Phalacrocorax sensu stricto (or subfamily "Phalacrocoracinae") cormorants and Leucocarbo sensu lato (or "Leucocarboninae") shags[25] does have some degree of merit. Fish and Wildlife Service issues permits for controlled cormorant shooting to protect fisheries. Classified in the UK as Green under the Birds of Conservation Concern 4: the Red List for Birds (2021). [37], In a common technique, a snare is tied near the base of the bird's throat, which allows the bird only to swallow small fish. Thus, they may be quite basal members of the Palacrocoracoidea. Prior to 2021, the IOU (or formerly the IOC) classified all these species in just Microcarbo, Phalacrocorax, and Leucocarbo. Pete Dunne's essential field guide companion.
