Part 33

This curious and well-known bird is only a very rare straggler to our shores. It breeds in the Camargue district at the mouth of the Rhone as well as in Spain, but its main breeding grounds are in Africa. It nests in colonies, the nests being conical structures, formed of mud, built near the edge of the water. It is now definitely ascertained that it sits with its long legs doubled up, and not straddle-legged as was stated by early travellers. The food consists of minute crustacea and other insects.

The adult is of a pale rose pink all over, darker on the wing coverts. The quills are black. Legs pink; bill rosy, with black tip. The young are of a pale mottled brown. Length about 5 ft.; wing 15 in.

THE GREY LAG GOOSE Anser cinereus, Meyer

Although about a century ago this bird used to nest in the fens of Cambridge and Lincolnshire, it has long since ceased to do so, and the only places where it may still be found breeding in these islands are in the north of Scotland and in the Outer Hebrides. In winter it occurs on our coasts in company with other species of Geese, but it is by no means common, and the majority pass on to the south, reappearing on their way north in spring. The food consists chiefly of grass and other green food, which it seeks on salt marshes near the sea by day, retiring to the shore to rest at night. It is the only Goose that breeds in our islands. The nest is begun in the middle of April and consists merely of a "scrape" amongst the grass or heather which is lined, as incubation proceeds, with down plucked from the body of the female. The eggs are usually six in number and dull yellowish white in colour.

As soon as the female begins to sit the males gather together in small flocks and take no further interest in their mates. Geese are strong fliers, and, being very wary birds, extremely difficult to approach. In flight they usually assume a wedge-shaped formation known as a "skein." The note is a harsh "gaggle, gaggle," like that of our domestic Goose, which is supposed to have originated from this species.

There is some doubt as to the origin of the name Grey Lag, but it is now generally conceded to have been applied to this species because it lagged behind after the other Geese had gone to their breeding quarters in the north.

The adult is greyish brown on the upper parts and breast, the rest of the under parts being whitish grey with a few black feathers. The young are rather darker and lack the black feathers underneath. Length 34 in.; wing 17 in.

THE WHITE-FRONTED GOOSE Anser albifrons (Scopoli)

This Goose, whose chief breeding grounds are in Siberia, though it also nests across the whole of Northern Europe, visits us in fair numbers every winter, but it is more abundant in the south and south-west than on the east coast, and is everywhere very local in its distribution.

It very closely resembles the Grey Lag Goose, but there is more white on the forehead; the bill is orange yellow with white nail, and the legs orange. Length 27 in.; wing 16 in.

THE BEAN GOOSE Anser segetum (J. F. Gmelin)

This species nests throughout Northern Europe and Asia. It is common on our coasts in winter, and is in fact the most abundant of our wild Geese. In Scotland, however, it is not so numerous as the preceding species.

This bird feeds inland on grain and vegetation.

The bill is black, with an orange band across the centre and a black nail; the amount of orange on the bill varies, however, in individuals, and several forms have been differentiated, though the matter requires further confirmation before being finally accepted. The amount of orange in the bill may also vary, in some cases, during the life of a single individual. Legs orange yellow. There is no bluish grey on the shoulder of the wing, as in the Grey Lag and Pink-footed. Length 34 in.; wing 19 in.

THE PINK-FOOTED GOOSE Anser brachyrhynchus, Baillon

On the east of England and Scotland this species is very plentiful during the winter, but in the south of England and on our west coasts it is comparatively rare, and its occurrence in Ireland is not yet authenticated. It breeds in Northern Europe and is apparently the only "Grey Goose" breeding on Spitzbergen.

The bill is black, with pink across the centre and a black nail. Legs pink. This pink colour has sometimes a yellowish tinge and so cannot be accepted as a definite character on which to diagnose this species. The wing, however, in the Pink-footed Goose is blue grey, approaching that of the Grey Lag, and this, together with its smaller size, will distinguish it from the preceding species. Length 28 in.; wing 17·5 in.

THE SNOW GOOSE Chen hyperboreus (Pallas)

This is a North American species, breeding in Arctic Regions and wandering south in winter. It has occurred several times in Ireland, and small flocks were seen in Cumberland, Northumberland, and Yorkshire during the severe winter of 1890-91.

The adult is pure white, with black quills. The young is brownish grey on the back, lighter on the under parts. Length about 30 in.; wing 17 in.

THE RED-BREASTED GOOSE Bernicla ruficollis (Pallas)

Only one or two examples of this rare Goose have been obtained in this country. It breeds in Eastern Siberia, whence it migrates southwards past the Ural and Caspian Seas.

The general colour above is black; the ear patches, throat, and breast chestnut; lores and belly white; chin black. Length 21 in.; wing 14·5 in.

THE BERNACLE GOOSE Bernicla leucopsis (Bechstein)

Nesting abundantly in Greenland and in some numbers on Spitzbergen, the Bernacle Goose is by no means uncommon in winter along the west coast of the United Kingdom as far south as Lancaster, as well as on the north coast of Ireland. Elsewhere in these islands it is decidedly rare. It feeds on grass pastures near the sea, almost invariably by night.

This species is commonly kept in captivity, where it breeds freely.

The crown of the head, neck, and upper breast are black; mantle grey, barred with black and white; forehead, cheeks, and chin white. Under parts greyish. Tail coverts pure white. Length 27 in.; wing 16 in.
