Anatinae. The Anatinae are a subfamily of the family Anatidae ( swans, geese and ducks ). Its surviving members are the dabbling ducks, which feed mainly at the surface rather than by diving. The other members of the Anatinae are the extinct moa-nalo, a young but highly apomorphic lineage derived from the dabbling ducks.
Sep 6, 2023 · The ecomorphological diversity within the ducks, geese and swans (Anatidae ) provides an appropriate model taxon for the trait-based comparative analysis of binocular fields. Since they have precocial chicks [ 39 ], binocular vision is not required for chick provisioning as occurs in other taxa [ 26 ].
The anatidae are the biological family of birds that includes the ducks, geese and swans. [1] These birds are common and widespread, and live in or near water. The family has a cosmopolitan distribution, on all the world's continents except Antarctica and on most of the world's islands and island groups. These are birds that are adapted for ...

The voices of the Anatidae vary from whistling sounds in whistling-ducks and sea ducks, to a variety of typical "quack" sounds in dabbling ducks and deep honks in swans. Most species posses a bulla, a more or less ossified enlargement at the union between that trachea and the bronchi, that acts as a resonating body.
Apr 1, 2006 · Spring migration is generally considered as a crucial period of the year for many birds, not the least due to its supposed importance for subsequent breeding success. By reviewing the existing literature for Anatidae (ducks, geese, and swans), we show that little is known about their ecology in spring, although some goose species are exceptions. Another general pattern is that the ecology of ...
