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. The females are smaller than the males, but otherwise both sexes look alike.

Range and Habits

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. Currently Alopochen aegyptiaca is colonizing the Netherlands, Belgium, and Germany.

gyptian 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.

Behavior

These geese stay together in small flocks throughout the year. 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.

Diet

Egyptian geese are mainly herbivores; they eat young grass from grasslands or savannahs, grains from agricultural fields, and soft vegetation like leaves and other detritus. Part of their diet includes a wide variety of small insects, terrestrial worms and frogs that live in nearby ponds.

Reproduction

The males are quite aggressive when mating. Each male performs a noisy and elaborate courtship display, emitting unusually loud honking noises. Egyptian geese are monogamous, one male and one female nest alone in dense vegetation, holes, or simply on the ground. They breed in the spring or at the end of the dry season. At the age of two, Alopochen aeygptiacus reach sexual maturity. Nest locations are usually near water for safety and near grassland for feeding. Pairs sometimes find nests on the ground or use deserted nests of other larger bird, which can be located in trees or on high ledges. Five to twelve eggs are laid, and they are incubated for 28 to 30 days. The young fledge in 70 days. 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.

Conservation Status

Egyptian geese are listed as Appendix III by CITES and in the IUCN Red List and evaluated as Least Concern.
