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.
Mating System: monogamous
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.
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: 5 to 12.
Range time to hatching: 28 to 30 days.
Average fledging age: 70 days.
Average age at sexual or reproductive maturity (female): 2 years.
Average age at sexual or reproductive maturity (male): 2 years.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; oviparous
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.
Parental Investment: no parental involvement; precocial ; pre-hatching/birth (Protecting: Male, Female); pre-weaning/fledging (Protecting: Male, Female)

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.
CITES: appendix iii
