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 ...

This is a list of the bird and mammal species and subspecies described as endangered by the United States Fish and Wildlife Service. It contains species and subspecies not only in the U.S. and its territories, but also those only found in other parts of the world. It does not include endangered fish, amphibians, reptiles, plants, or invertebrates.
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).
Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. In December 2019, the International Union for Conservation of Nature (IUCN) listed 460 endangered avian species. [1] Of all evaluated avian species, 4% are listed as endangered. No subpopulations of birds have been evaluated by the IUCN.
A species may be endangered or vulnerable, but not considered rare if it has a large, dispersed population. IUCN uses the term "rare" as a designation for species found in isolated geographical locations. Rare species are generally considered threatened because a small population size is less likely to recover from ecological disasters.
The diving ducks, commonly called pochards or scaups, are a category of duck which feed by diving beneath the surface of the water. They are part of Anatidae, the diverse and very large family that includes ducks, geese, and swans. The diving ducks are placed in a distinct tribe in the subfamily Anatinae, the Aythyini.
