Egyptian goose
The Egyptian goose, or Nile goose, is a large bird more closely related to ducks than to true geese, belonging to the genus Alopochen. This species is notable for its striking appearance, featuring reddish-orange and brown plumage with distinctive white and black markings, and a pink bill and webbed feet. Historically, the Egyptian goose held a sacred status in ancient Egypt, often depicted in art and monuments. In the wild, they thrive in tropical regions of sub-Saharan Africa and are known for their social behavior, typically feeding in pairs or small flocks.
These birds are herbivorous, primarily consuming grass, seeds, and grains, and they exhibit a unique feeding routine, foraging in the early morning and evening while resting during the hottest part of the day. Breeding occurs year-round in Africa, with nests built from twigs and leaves in various locations, including trees and dense vegetation. Female Egyptian geese lay between 5 to 11 eggs, which they incubate for about 28 to 30 days. Goslings develop flight feathers within three months and are cared for by both parents for an additional four months. With a lifespan of 15 to 25 years in the wild, the Egyptian goose continues to be a vibrant part of its ecosystem.

Egyptian goose
The Egyptian goose, called the Nile goose, is not a "true goose" but a sheldgoose closely related to ducks and the only living member of the genus Alopochen. Ancient Egyptians believed the bird was sacred and often painted or carved it into monuments. It remains one of the most populous birds in sub-Saharan Africa.
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Anseriformes
Family: Anatidae
Genus: Alopochen
Species: Aegyptiacus
These large birds resemble geese but are more closely related to ducks. Egyptian geese are 2 to 2 1/2 feet (63 to 73 centimeters) long and have wingspans of 4 1/2 to 5 feet (1 to 1 1/2 meters). They may weigh 2 1/5 to 8 4/5 pounds (1 to 4 kilograms). Reddish-orange or brown plumage with tiny black flecks make up the wings’ visible feathers, while the undersides are white with black and green patches. Their breasts and underparts are a light cinnamon color with white specks. Chestnut neck feathers match the round patches around the orange eyes. The Egyptian goose's webbed feet, bill, and long legs are pink, but its tail is black.
Egyptian geese feed on grass, leaves, seeds, and young grain crops in the water and fields of their tropical habitats. They often live and feed in pairs or small flocks. They feed for a few hours early in the morning before resting and moving to another feeding site. They rest and drink during the hottest hours of the day, bathing and preening near the water's edge with other birds. Crocodiles and hippopotamuses may be present, and a goose may perch on a hippo. The birds eat again in the early evening before returning to their roosts for the night.
While feeding, the geese watch for snakes, monitor lizards, and large birds of prey. If they sense danger from these predators, they make an alarm call. During the molting, or shedding, season, the geese cannot fly and may try swimming away from danger.
Any time of the year is suitable for breeding in Africa. Birds in Europe breed in March and April. Nesting sites may be hollow trees, high tree branches, dense vegetation near water, or burrows in the ground. Competition for nesting sites and territories causes fights among the males. Females build nests from twigs and leaves and lay 5 to 11 cream-white eggs on a soft lining of downy feathers. After 28 to 30 days of incubation, the eggs hatch. The goslings develop their flight feathers about three months later but receive care from both parents for about 4 months. Goslings reach full maturity around two years of age.
The life span of the Egyptian goose is between 15 and 25 years in the wild, though they can live longer in captivity.
Males make a deep, breathy call, while females honk and trumpet loudly.
