Notice the hesitation in the gender of the epithet of the scientific names, as they are usually masculine, but in the case of the whiskered tern is mostly used as feminine, maybe from the influence of the previous gender used, Sterna.
The black-bellied tern and the white-cheeked tern might also be placed in Chlidonias.
