Egyptian Goose

Overview

The Egyptian goose (Alopochen aegyptiaca) is an African member of the Anatidae family that swims well and appears heavy in flight, resembling a goose more than a duck. It is widespread and common in its native range, though it has also been introduced to Europe, the United States, and other regions as an ornamental species.

Identification

• Size ranges from 63–73 cm in length, with males typically larger than females.
• Plumage varies greatly in tone, ranging from grey to brown, with a large white portion of the wings that is hidden when at rest but displayed during alarm or aggression.
• The male produces a hoarse, subdued quack and a louder, breathy call resembling a steam engine, while the female emits a far noisier, raucous quack.

Habitat

Native to sub-Saharan Africa and the Nile Valley, the species inhabits open or semi-open areas near fresh water, ranging from lowlands to 4,000 m in the Ethiopian Highlands. It is largely absent from dense forests and deserts, though it disperses to arid regions such as the Sahel and occasionally North Africa when not breeding.

Diet

This species typically feeds on cereal crops, leaves, and grasses, occasionally consuming locusts, worms, and other small animals. Goslings initially rely on small aquatic invertebrates and freshwater plankton, a diet that makes them vulnerable to botulinum toxin in anoxic conditions.

Egyptian geese are known to engage in aerial 'dogfights' to chase away intruders and have been observed attacking drones that enter their habitat.
