The SEA GEESE (_Bernicla_) are comparatively small, compactly-built
birds, with short necks and moderately large heads; the short delicate
beak is strong, broad and high at its base, slender towards its tip, and
slightly denticulated at its margins; the foot is low, but powerful; and
the wing so long as to extend as far as the tip of the short tail, which
is rounded at its extremity. The thick plumage is principally of a deep
grey, marked with black, white, and reddish brown. These Geese are met
with in the extreme north of Europe, Asia, and America; the American,
formerly considered as distinct from the European, being evidently only
a variety. The home of these birds is to be found upon the coasts and
islands situated between 60° and 80° of north latitude. Only a few breed
in Iceland; but in Spitzbergen they are very numerous, and further east
they abound throughout the summer along all the shores of the Icy Ocean;
they are likewise numerous in Hudson's Bay and the neighbouring waters.
From the above inhospitable regions they make annual pilgrimages to
warmer climates, appearing in Great Britain towards the end of October
or the beginning of November. At this time they crowd the vicinity of
the coast in thousands and tens of thousands; far as the eye can reach
they may sometimes be seen wading around the banks of sand and amid the
shallows left by the receding tide; their cries are to be heard above the
roar of the surf; and the masses, when they take flight and rise into the
air, resemble at a distance a thick and wide-spread smoke, their numbers
being absolutely incalculable. A few individuals may also be sometimes
seen in the interior of the country upon lakes and other large sheets of
water; these, however, can only be regarded as stragglers: all Sea Geese
well deserve the name, as under ordinary circumstances they never leave
the coast. As relates to their ordinary food, these birds differ from
Common Geese in so far that, besides grass and marine plants, they eat
a considerable proportion of animal food. In northern regions they feed
upon whatever is there to be met with. With us they prefer meadow grass
and tender herbage. In captivity they readily feed upon grain, to which,
however, should be added a considerable proportion of green vegetables.
THE BRENT GOOSE.
The BRENT GOOSE (_Bernicla torquata_) is black upon the head, neck,
quills, and tail; the feathers on the breast, back, and upper belly are
dark grey, with light tips; the sides of the belly, rump, and upper
tail-covers are white; the sides of the throat are decorated with a white
crescent-shaped patch. The young are without the white feathers on the
throat, and are darker than the adult birds.
