Ardenna
Introduction '''''Ardenna''''' is a genus of seabirds in the family Procellariidae. These medium-sized shearwater species were formerly included in the genus ''Puffinus''.
Taxonomy A phylogenetic analysis using mitochondrial DNA published in 2004 found that ''Puffinus'' contained two distinct clades and was polyphyletic. To create monophyletic genera a group of species were moved into ''Ardenna'', a genus that had been introduced in 1853 by Ludwig Reichenbach with the great shearwater as the type species. Reichenbach cites the Italian naturalist Ulisse Aldrovandi who in 1603 used the spelling "Artenna" for a seabird. Recent genomic studies have validated the phylogenetic distinction between ''Ardenna'' and ''Puffinus''.===Species===The genus contains these seven living species: Image  Scientific name  Common Name Distribution120px  ''A. pacifica'' Wedge-tailed shearwater Northern and Western Australia120px   ''A. bulleri'' Buller's shearwater across most of the Pacific Ocean 120px  ''A. grisea ''  Sooty shearwater or muttonbird  widespread in Pacific and Atlantic Oceans120px  ''A. tenuirostris''   Short-tailed shearwater or muttonbird Southern Australia120px  ''A. creatopus''   Pink-footed shearwater  Pacific Ocean120px  ''A. carneipes''  Flesh-footed shearwater southwest Pacific Ocean includes Lord Howe Island, South Australia and northern New Zealand 120px   ''A. gravis ''  Great shearwater  Atlantic===Phylogeny===Phylogeny based on a study by Joan Ferrer Obiol and collaborators published in 2022.
