The first definition includes frigates and pelicans, cormorants and sulids. The name comes from the ancient Greek word pelican (πελεκάν), which comes from the word pelekys (πελεκυς) meaning "ax". In ancient times, the word for both the pelican and woodpeckerPelicans Pelecaniformes give his name to have been applied, an order that has had a varied taxonomic history. Molecular evidence that the Hamerkop Shoebill and form a sister group of pelicans, although there are doubts about the exact relationship between the three lines.
