The Madagascar pochard or Madagascan pochard (Aythya innotata; Malagasy: Fotsy maso, Onjo [2]) is an extremely rare diving duck of the genus Aythya. Thought to be extinct in the late 1990s, specimens of the species were rediscovered at Lake Matsaborimena near Bemanevika in Madagascar in 2006. By 2017, a captive breeding program had produced a ...
Anseriformes (Anser being Latin for "goose") is the taxonomic order to which the ducks, geese, swans, and screamers belong. BirdLife International has assessed 166 species; 89 (54% of total species) have had their population estimated. A variety of methods are used for counting waterfowl.
Additionally 55 avian species (0.48% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [3]
This is a list of the breeds of domestic duck which have official recognition at national or international level. [1]Most breeds of duck derive from the wild mallard, Anas platyrhyncos, while a small minority are descendants of the Muscovy duck, Cairina moschata.
Ducks generally only have one partner at a time, although the partnership usually only lasts one year. [26] Larger species and the more sedentary species (like fast-river specialists) tend to have pair-bonds that last numerous years. [27] Most duck species breed once a year, choosing to do so in favourable conditions (spring/summer or wet seasons).
The species name is the Latin word ferina, meaning "wild game" (derived from ferus, meaning "wild"). [10] The common name "pochard" was first applied to the duck in the mid-1500s; its origin and etymology is unknown. [11] It is also sometimes known as European pochard, Eurasian pochard, or (particularly in the UK) simply pochard. [12]
