Egyptian Goose

I his bird lives in marshes, lakes, and rivers, where it sometimes swims and dives, but it is more.usually seen on land. It grazes on grass also eating leaves and seeds of plants including crops, and possibly occasional insects. The female can be distinguished by her trumpetlike quacking, in contrast with the male's soft, husky calls. Pairs mate for life, forming flocks after breeding that perch and roost in trees.

• NEST A hollow in the ground under vegetation, or a hole in a cliff, cave, or tree.

• DISTRIBUTION I Ipper Nile Valley and Africa south of the Sahara; introduced in England.

• REMARK Although it is called a goose, this bird is really a species of shelduck.

distkim tion

I his rare goose is a migrant to the Arctic, breeding on mountain tundra and feeding mainly on grasses and sedges. Other foods include broadleaved plants, roots, tubers, and, in winter, cultivated grain. Migrating birds fly in ragged groups or in slanting lines, rather than in the V formation well known in other species of geese. The frequent call is a harshly piercing, double note. • NESTA hollow, lined with down and feathers, in the top of a raised piece of ground. Pairs often choose a site close to the nest of a Peregrine Falcon (see p. 105). Surprisingly, this relationship gives protection to the geese, as the falcon attacks or deters any predators that approach the nest
