Alopochen aegyptiacaEgyptian goose

Geographic Range

Alopochen aegyptiaca is widely distributed throughout its native range, Africa, and southern Europe. It is especially common in southern Africa, below the Sahara and in the Nile Valley. In the 18th century, Alopochen aegyptiaca was introduced into Great Britain, and a substantial population still thrives there today. Currently Alopochen aegyptiaca is colonizing the Netherlands, Belgium, and Germany. (Lensink, 1998; VanPerlo, 1999)


Egyptian geese will not populate densely wooded areas, though they can be found in meadows, grasslands, and agricultural fields. Most of their time is spent in rivers, streams, lakes, ponds and wetlands. They can be found as high as 4000 m. (Jensen, et al., 2002; McLachlan and Liversidge, 1940; VanPerlo, 1999)

Physical Description

Egyptian geese have long necks, long pink legs, a pink bill and brown eye patches encircling each eye. They are distinguished from closely related species by a brown patch in the middle of the chest. The upper wings and the head are brown, while the rest of the body is light brown. The underside of the wings is white and green. Juveniles do not have the brown eye patches or a patch on the chest.

Egyptian geese are anywhere from 63 to 73 cm in height and they can weigh from 1.5 to 2.3 kg. The wingspan is fairly large, measuring 38 cm, on average.

Distinguishing between males and females can be a challenge. The females are smaller than the males, but otherwise both sexes look alike. One way to tell them apart is by their sound. Males make a raspy hiss, while females produce a cackling sound. Although they are not terribly vocal, when they are feeling aggressive or stressed they will make a great deal of noise. (Jensen, et al., 2002; Newman, 1983; Sclater, 1906; VanPerlo, 1999)

The males are quite aggressive when mating. Each male performs a noisy and elaborate courtship display, emitting unusually loud honking noises. Under normal circumstances, Egyptian geese are reserved, quiet animals, but during mating season they are just the opposite. A male will act in this manner in order to attract a female. Since Egyptian geese are monogamous, one male and one female nest alone in dense vegetation, holes, or simply on the ground. (Newman, 1983; Priest, 1929)

Egyptian geese breed in the spring or at the end of the dry season (The breeding season is anywhere from July to March, depending on the area). At the age of two, Alopochen aeygptiacus reach sexual maturity. Nest locations are usually near water for safety and near grassland for feeding; the nests are made out of feathers and vegetation and are located in dense vegetation, holes, or simply on the ground. Pairs sometimes find nests on the ground or use deserted nests of other larger bird species (such as Buteo buteo (common buzzard) or Pica pica (black-billed magpie)), which can be located in trees or on high ledges. The male goose fertilizes the female internally. Five to twelve eggs are laid, and they are incubated for 28 to 30 days. The young fledge in 70 days. (Lensink, 1998; Priest, 1929; VanPerlo, 1999)

  • Breeding interval
    Egyptian Geese breed just once each year.
  • Breeding season
    The majority breed in the spring or at the end of the dry season. The breeding season is anywhere from July to March, depending on the area.
  • Range eggs per season

  • Average fledging age

  • Average age at sexual or reproductive maturity (female)
    2 years
  • Average age at sexual or reproductive maturity (male)
    2 years

Incubation lasts from 28 to 30 days and is done by both parents. The father protects the eggs and chicks, while the mother guides them and keeps them close to her. The chicks are precocial. (Priest, 1929; VanPerlo, 1999)

The lifespan of Alopochen aegyptiacus in the wild has not been documented. At the Woodland Park Zoo, an Egyptian goose lived for fourteen years. (Jensen, et al., 2002)

These geese stay together in small flocks throughout the year, mainly for protection. Egyptian geese pair up during the breeding season, but otherwise they remain in their flocks. Although they are mainly sedentary, they move to another body of water if a period of drought occurs in their current home range. They may wander from the water during the day in search of food in either the grasslands or agricultural fields. They always return to the water at night. (VanPerlo, 1999)

Home Range

The geese usually settle in one pond, lake, stream or river for their entire lives, unless predators become too abundant or drought occurs. (Petri, 1998; Prozesky, 1970; VanPerlo, 1999)

Communication and Perception

Distinguishing between male and female Egyptian geese can be a challenge. One way to tell them apart is by their sound. Males make a raspy hiss, while females produce a cackling sound. Although they are not terribly vocal, when they are feeling aggressive or stressed they will make a great deal of noise.

The males are quite aggressive when mating. Each male performs a noisy and elaborate courtship display, emitting unusually loud honking noises. (Newman, 1983; VanPerlo, 1999)

Food Habits

Egyptian geese are mainly herbivores, they eat young grass from grasslands or savannahs, grains (particularly wheat) from agricultural fields, and soft vegetation like leaves and other detritus. Many tend to forage away from the water in pastures or arable land. Part of their diet includes a wide variety of small insects, terrestrial worms and frogs that live in nearby ponds. (Mangnall and Crowe, 2002; VanPerlo, 1999)

  • Animal Foods
  • amphibians
  • insects
  • terrestrial worms
  • Plant Foods
  • leaves
  • seeds, grains, and nuts


Egyptian geese swim, travel and feed in flocks. Living in flocks may be a defense against predators since there are more individuals present to look out for predators and give a warning.

Predators include: lions (Panthera leo), cheetahs (Acinonyx jubatus), hyenas (subfamily Hyaeninae), crocodiles (genus Crocodylus) and vultures (family Accipitridae). (Lensink, 1998; Petri, 1998)

Ecosystem Roles

Since these geese tend to eat much of their food on land, they help disperse seeds, break up soil and decompose dead plants. (Lensink, 1998; Sclater, 1906)

Economic Importance for Humans: Positive

Alopochen aegyptiacus are not hunted by many people because they live in such remote locations, but some farmers may shoot at them to scare them away from their agricultural fields. Egyptian Geese may also aid in decreasing pest populations around lakes or fields. (Mangnall and Crowe, 2002)

  • Positive Impacts
  • food
  • controls pest population

Economic Importance for Humans: Negative

Due to the large numbers of Egyptian geese in southern Africa, farmers have been known to complain about attacks on their crops. Groups of geese graze on young, sprouting plants, causing great damage to the farmer's crops. (Jensen, et al., 2002; Mangnall and Crowe, 2002)

  • Negative Impacts
  • crop pest

Conservation Status

As the most widely distributed member of their family in Africa, Egyptian geese seem to be managing quite well. Due to the increased availability of water in Southern Africa, numbers have gone up in the past few years. Egyptian geese are listed as Appendix III by CITES.
