Birds
"The Capercali," says Mr. Lloyd, "is to be found in most parts of the
Scandinavian peninsula; indeed, as far to the north as the pine-tree
flourishes, that is to say, very near to the North Cape itself. These
birds are, however, very scarce in the more southern of the Swedish
provinces. The favourite haunts of the Capercali are extensive fir-woods.
In coppices or small covers they are seldom or never to be found."
Professor Nilsson observes that such as breed in the larger forests remain
there all the year round, but those on the contrary that breed on the
sides of elevated mountains, or in more open parts of the country, in the
event of deep snow, usually descend to the lower grounds.
The principal food of the Capercali, when in a state of nature, consists
of the leaves and tender shoots of the Scotch fir (_Pinus sylvestris_). He
very rarely feeds upon those of the spruce (_Pinus abies_). He also eats
juniper-berries, blue berries, and other berries common to the northern
forests, and also, occasionally in the winter time, the buds of the birch,
&c. The young Capercali feed principally at first on ants, worms, and
insects.
In the spring of the year, and often when the ground is still deeply
covered with snow, the cock stations himself on a pine, and commences
his love song, or _play_, as it is termed in Sweden, to attract the hens
about him. This performance is usually carried on from the first dawn of
day to sunrise, or from a little after sunset, until darkness has set
in. The time, however, more or less depends upon the mildness of the
weather, and the advanced state of the season. During his play the neck
of the Capercali is stretched out, his tail is raised and spread like a
fan, his wings droop, his feathers are ruffled up, and, in short, he much
resembles in appearance an angry Turkey-cock. He begins his play with
a call, something resembling the words "Peller, peller, peller." These
sounds he repeats at first at some little intervals; but, as he proceeds,
they increase in rapidity, until at the last, and after perhaps the lapse
of a minute or so, he makes a sort of gulp in his throat, and finishes
by drawing in his breath. During the continuance of this latter process,
which only lasts a few seconds, the head of the Capercali is thrown up,
his eyes are partially closed, and his whole appearance would denote that
he is worked up into an agony of passion.
"On hearing the call of the cock, the hens, whose cry in some degree
resembles the croak of the Raven, or rather, perhaps, the sound of 'gock,
gock, gock,' assemble from all parts of the surrounding forest. The male
bird now descends from the eminence on which he was perched to the ground,
where he and his female friends join company.
