The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 174 species in 43 genera.
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae, Anseranatidae, and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed though this one is not.
Anas is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was split into four separate genera. The genus now contains 31 living species. The name Anas is the Latin for "duck".
The Brazilian teal or Brazilian duck is the only duck in the genus Amazonetta. It is widely distributed in eastern South America.
Chloephaga is a genus of sheldgeese in the family Anatidae. Other sheldgeese are found in the genera Alopochen and Neochen.
Anser is a waterfowl genus that includes the grey geese and the white geese. It belongs to the true goose and swan subfamily of Anserinae under the family of Anatidae. The genus has a Holarctic distribution, with at least one species breeding in any open, wet habitats in the subarctic and cool temperate regions of the Northern Hemisphere in summer. Some also breed farther south, reaching into warm temperate regions. They mostly migrate south in winter, typically to regions in the temperate zone between the January 0 °C (32 °F) and 5 °C (41 °F) isotherms.
This is a list of the fauna of Finland. Finland borders Sweden to the west, Russia to the east, and Norway to the north, while Estonia lies to its south across the Gulf of Finland, allowing an ecological mix. Finland contains many species of mammals, birds, and fish, but only a few reptiles and amphibians. This article discusses all the vertebrate animals which can be found on Finland itself, not the oceans.
Tyzzeria is a genus of parasitic alveolates that with one exception infect the cells of the small intestine.
Faunia is a zoo and a botanical garden located in Madrid, Spain. It covers about fourteen square hectares and is organized into areas representing different ecosystems, such as jungle, polar regions, and African forest. It is owned by Parques Reunidos, SA.
The Murrough Wetlands are a 15-kilometre (9.32 mi) long complex of coastal wetlands in County Wicklow, Ireland. The main wetland is centred around Broad Lough immediately north of Wicklow town. Broad Lough is a large estuarine lake that is cut off from the Irish sea by a long, thin shingle ridge. Smaller, disconnected wetland areas such as the East Coast Nature Reserve and the Kicoole Marshes are also included in the complex. The Murrough Wetlands are the most extensive wetland area on the east coast of Ireland, and are an EU-designated Special Area of Conservation and Special Protection Area.
