text: The Sandwich tern was originally described by ornithologist John Latham in 1787 as Sterna sandvicensis, but was recently moved to its current genus Thalasseus (Boie, 1822) following mitochondrial DNA studies which confirmed that the three types of head pattern (white crown, black cap, and black cap with a white blaze on the forehead) found amongst the terns corresponded to distinct clades.
