Mute swan Cygnus olor, photographed by Andrew Dunn.

Belongs within: Anatidae.
Contains: Branta, Anser.

The Anserinae contains the swans and (the majority of the) geese. In general, Anserinae have longer necks than most other waterfowl, and more robust, less flattened bills. However, recent phylogenetic analyses (e.g. Burleigh et al. 2015) place the pink-eared duck Malacorhynchus membranaceus of Australia as a basal anserine despite its short neck and broadly flattened bill. Also placed within the Anserinae are the coscoroba Coscoroba coscoroba, a white swan-like bird from southern South America, and the Cape Barren goose Cereopsis novaehollandiae of southern Australia. Cnemiornis, a recently extinct genus of two species of large flightless goose from New Zealand, is generally believed to have been closely allied to the Cape Barren goose.

The swans of the genus Cygnus are particularly large and long-necked birds. The majority of swan species are found in higher latitudes of the Northern Hemisphere and are predominantly white in coloration. However, distinctive in both distribution and coloration are the black swan Cygnus atratus of Australia and the black-necked swan C. melancoryphus of South America. The mute swan Cygnus olor has an orange-red bill with a large black knob at the base, and has been widely introduced outside its native Palaearctic range as an ornamental bird.
