| English name |
Greylag Goose |
| Scientific name |
Anser anser L. |
| Measures |
The largest and heaviest of Anser
geese, with the size of a little swan. The wing length is 42 - 48 cm and weight about 3 -
4.5 kg |
| Distribution |
The most widespread goose in Europe breeds
on the lakes in the natural zones of the mixed and broad-leaved forests, steppes and
deserts. In Estonia it breeds on the bays of the western coast and in the Western
Archipelago. |
| Abundance |
The Greylag Goose is comparatively
abundant. At present, 1,500 pairs are breeding in Estonia. |
| Habitat |
It inhabits coastal bays and relict lakes
rich in emergent vegetation (especially reeds), and islets in the sea. |
| Migration |
Migratory bird. The geese appear on an
average in mid-March. The majority of local birds departs at the end of September. |
| Feeding |
Herbivorous bird with no exception. Feeds
on the aquatic plants and shoots of grasses. It feeds while walking rather than swimming. |
| Breeding |
The nest is situated mainly in an open
area in or near the reed bed. The reed shoots and other water plants are used for building
the nest on an higher area or clod. After mid-April it lays 4 - 8 white eggs. Only females
sit on the eggs. They are very sensitive to disturbance. |
| Development |
The young geese are capable to follow the
female soon after hatching and drying. They leave the nest and start moving around the
nesting area. They move to open sea for June and spend their moulting time on small
islands or islets. |
| Endangerment and protection |
The adult Greylag Goose has relatively few
natural enemies. Only the young birds will be attacked by predators if they happen to be
left without parents' care. Greylag goose is a valuable bird for hunting. It is endangered
by the pollution of waters and disturbance in breeding areas. |
