The brent goose arrives in our islands in the autumn, and remains through the winter in suitable localities in various parts of the coast, from the Orkneys and Shetlands in the north to the Channel Islands; it is, however, most abundant on the north-east coast of England. In most years old and young birds arrive together in flocks; in other years only adults appear, and it is supposed that in such seasons exceptionally cold weather has prevented the eggs from hatching. The brent differs from its nearest ally, the barnacle goose, in its slightly smaller size, darker plumage, which is nearly black, and its more marine habits. With us it spends most of the time out at sea, visiting the tidal flats early and late in the day, and at night, to feed on the wrack grass (Zostera marina). Mr. Abel Chapman has graphically described this goose in his ‘Bird Life on the Border.’ It is, he says, the last of our winter visitors to arrive, seldom coming in force until the new year. Their affections are so hyperborean that they will come no farther south than they are actually compelled by food requirements, being driven reluctantly southwards, point by point, before the advancing line of the winter’s ice. He writes: ‘On alighting at the feeding-grounds the geese at once commence greedily to pull up and devour the blades of the sea-grass, the whole flock advancing in the closest order over the green oozy mud, all heads down except the sentries, of which an ample number are always discernible.... After finishing their morning meal, about noon, the geese are disposed to rest, and spend the middle of the day floating about on the water, preening themselves, and, in mild weather, splashing about, and chasing each other in sheer exuberance of spirit.... Towards evening the geese recommence feeding, and so intensely eager are they about sunset to utilise the few remaining minutes that they then, perhaps, offer the most favourable chance to get within shot.... Just at dark the whole host rise on wing together, and make for the open sea. In the morning they come in by companies and battalions, but at night they go out in a solid army; and a fine sight it is to witness their departure. The whole host, perhaps ten thousand strong, here massed in dense phalanxes, elsewhere in columns, tailing off into long skeins, V’s, or rectilinear formations of every conceivable shape, but always with a certain formation—out they go; ... while their loud clanging honk honk, and its running accompaniment of lower croaks and shrill bi-tones, resound for miles around.’
Barnacle Goose.
Bernicla leucopsis.
Fig. 77.—Barnacle Goose. ¹⁄₁₀ natural size.
Head, neck, and throat black; forehead, cheeks, and chin white; a black stripe between the eye and bill; mantle lavender-grey barred with bluish black and white; wing and tail feathers blackish; breast and belly greyish; vent and tail-coverts pure white; flanks barred with grey; bill, legs, and feet black. Length, twenty-five inches.
The present species is not nearly so abundant as the brent, and not so exclusively marine in its habits. It sometimes visits inland districts, and although it feeds on the mud-flats like the brent, it leaves them as soon as the tide rises, and repairs to some grassy bank of a river or lake, where it feeds. The breeding habits of this species are not known; it is believed to have its nesting-grounds in Spitzbergen and Nova Zembla.
