The Mute Swan (Cygnus olor) is a species of swan, and thus a member of the duck, goose and swan family Anatidae. It is native to much of Europe and Asia, and (as a rare winter visitor) the far north of Africa. It is also an introduced species in North America, Australasia and southern Africa. The name ‘mute’ derives from it being less vocal than other swan species.Measuring 125 to 170 centimetres in length, this large swan is wholly white in plumage with an orange bill bordered with black. It is recognisable by its pronounced knob atop the bill

Wild Duck (pato-real)

Scientific name: Anas platyrhynchos

The Mallard, or Wild duck (Anas platyrhynchos), probably the best-known and most recognizable of all ducks, is a dabbling duck which breeds throughout the temperate and sub-tropical America, Europe, Asia, New Zealand (where it is currently the most common duck species), and Australia.

The male birds have a bright green head, while the female’s is light brown. The mallard lives in wetlands, eats water plants, and is gregarious. It is also migratory. The mallard is the ancestor of all domestic ducks, and can interbreed with other species of genus Anas.This interbreeding is causing rarer species of ducks to become genetically diluted.

O pato-real (Anas platyrhynchos) é uma ave anseriforme que habita áreas temperadas e sub-tropicais das Américas, Europa e Ásia. A espécie tem forte dimorfismo sexual, tendo os machos uma cabeça de cor verde muito característica. É o antecessor da maioria dos patos domesticados actuais.
