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

The Egyptian Goose (Alopochen aegyptiacus) is a member of the duck, goose and swan family Anatidae. It is in the shelduck subfamily Tadorninae, and is the only extant member of the genus Alopochen. mtDNA cytochrome b sequence data suggest that the relationships of Alopochen to Tadorna need further investigation (Sraml et al. 1996).

O ganso-do-egipto (Alopochen aegyptiacus) é uma ave anseriformes do grupo dos gansos. É também conhecido por ganso-do-nilo, ganso-raposo e em Angola por balandira. A sua área de distribuição inclui Europa e África. É especialmente comum a sul do Saara e vale do Nilo.
