Although they are mainly sedentary, they move to another body of water if a period of drought occurs in their current home range. Living in flocks may be a defense against predators since there are more individuals present to look out for predators and give a warning. Egyptian geese swim, travel and feed in flocks. Egyptian geese pair up during the breeding season, but otherwise they remain in their flocks. These geese stay together in small flocks throughout the year, mainly for protection. The Egyptian goose generally avoids densely forested areas, appearing to prefer water bodies with open shorelines, close to grasslands or agricultural land where it can graze. This species inhabits a variety of wetland habitats in open country, including rivers, dams, lakes, reservoirs, marshes, estuaries, sewage works and sometimes offshore islands, and it occurs at elevations of up to around 4,000 metres in Ethiopia. One way to tell them apart is by their sound. The females are smaller than the males, but otherwise both sexes look alike. Distinguishing between males and females can be a challenge.
The wingspan is fairly large, measuring 38 cm, on average. Egyptian geese are anywhere from 63 to 73 cm in height and they can weigh from 1.5 to 2.3 kg.
The Egyptian goose ( Alopochen aegyptiaca) is a member of the duck, goose, and swan family Anatidae.
