Egyptian goose (Alopochen aegyptiacus) breeds widely in Africa except in deserts and dense forests, and is locally abundant. They are found mostly in the Nile Valley and south of the Sahara.
It has also been introduced in Great Britain dating back to the 18th century, though only formally added to the British list in 1971. In Britain, it is found mainly in East Anglia, in parkland with lakes. This species will nest in a large variety of situations, especially in holes in mature trees in parkland. The female builds the nest from reeds, leaves and grass, and both parents take turns incubating eggs. Egyptian Geese usually pair for life. More: en.wikipedia.org/wiki/Egyptian_Goose
