Description
Family Anatidae
Birds that are modified for swimming, floating on the water surface, and in some cases diving in at least shallow water. They have webbed feet and flattened bills. Special oils in their feathers helps them shed water. This is one of the few families of birds that possess a penis .
Physical Description
Species Alopochen aegyptiacus
These handsome large geese have patches of chestnut-colored feathers
around each eye, which give them a spectacled appearance
. Some of them have gray-brown upper parts; others are red-brown. They have black tails and yellow eyes; their bills, legs
and feet are pink. Sexes are alike, but the females are somewhat smaller.
Males hiss and females make a cackling noise.
Habitat
Egyptian Geese are usually found inland and close to water.
Typically found in water with a depth of 0 to -282 meters (0 to -925 feet).[1]
Biome: Saltwater . Bathydemersal .
Biology
Diet
Their staple diet consists of grass and herbs. But during the dry season , when their natural food becomes less attractive, they often visit cultivated areas and can cause considerable damage to drops. They also eat some worms and insects.
Reproduction
Although very quarrelsome and bad-tempered by nature, they form strong
pair bonds and are excellent parents.
Egyptian Geese use a surprising variety of nest
sites. Some nest on the ground
, some in burrows, others prefer using ledges on cliffs
or old buildings. Some select abandoned nests of other birds, often high in the crowns of trees
.
Parents call
from below to the young that hatch
at high elevations
until the babies find courage to step off into space.
Females incubate a clutch
of 5-8 eggs
for about 28 days.
Behavior
Egyptian Geese are very pugnacious and aggressive, especially during breeding season
. They are intolerant
of other birds including individuals of their own kind and are among the most vicious of all waterfowl.
Essentially terrestrial
, they spend considerable time ashore and are at ease on land
. They feed
both night and day, often long distances
from water. They are good swimmers and dive extremely well.
