Nannopterum is a genus of cormorant comprising three species. They are found throughout the Americas, hence the common name American cormorants.
These species were formerly classified in the genus Phalacrocorax. A molecular phylogenetic study of the cormorants published in 2014 found that these three species formed a clade that was sister to the genus Leucocarbo.[1] To create monophyletic genera, the three species were moved the resurrected genus Nannopterum that had been introduced in 1899 by English ornithologist Richard Bowdler Sharpe to accommodate the flightless cormorant.[2][3][4] The genus Nannopterum is thought to have split from Leucocarbo between 6.7 - 8.0 million years ago.[1]
The genus name Nannopterum combines the Ancient Greek nannos meaning "dwarf" with pteron meaning "wing".[5] This name was coined for the flightless cormorant, which does indeed have small wings. Genetic studies have found that the neotropic and double-crested cormorants form a clade with the flightless cormorant, and they are thus placed together in the genus Nannopterum despite both species having normal-sized wings and full flight capabilities.[4]
