The smew, or nun, as it is sometimes called, is usually placed among the irregular visitors to the British Islands, and hardly comes within the scope of this book; but there is reason to believe that it is present every winter, although sometimes in very small numbers, in the seas around our coasts; and it has, therefore, some claim to be described as a British species. Females and immature birds, called red-headed smews by fishermen, are frequently met with on the east coasts of England and Scotland; males in the beautiful mature plumage are very rare, it is supposed because they do not approach the shore, except in very severe weather.
In its breeding habits the smew resembles the goosander, laying its eggs in the trunk of a hollow tree. Finnish Lapland is said to be the western limits of its breeding range.
Wood-Pigeon, or Ringdove.
Columba palumbus.
Head bluish grey; sides and back of neck glossed with violet and green, bounded on each side by a patch of white; upper parts grey, the wing-coverts broadly edged with white, forming a conspicuous bar; tail-feathers dark slate-grey; under parts reddish purple, pale on the belly; bill orange, powdered with white at the base; legs and feet bright red. Length, seventeen inches.
Of the four species of British doves, the wood-pigeon is the most interesting, as well as the best known, on account of its large size, its abundance, and general diffusion throughout the country, and its plaintive music, so familiar to everyone; not in the rural districts only, but even in London town, where this bird exists in a semi-domestic state, and is seen to be actually tamer than the domestic pigeons it frequently associates with. Like most widely diffused and well-known species, it is called by various names: quest and cushat in the north, and, in England, ringdove and wood-pigeon. The last name, which it once shared with the stock-dove, is now becoming the most general.
For many years past the wood-pigeon has been increasing in numbers, and, in Scotland, extending its range; this is no doubt due to the spread of cultivation and the planting of trees, and to the extirpation of its natural enemies, the rapacious birds, by gamekeepers. But, in spite of all this, it is really surprising that the wood-pigeon should continue to increase, considering that it is one of the most persecuted of wild birds, and is perpetually being shot at by everyone in possession of a gun, from various motives. It affords good sport, and is a good bird for the table, and is heartily disliked by the farmers. It is an exceedingly voracious feeder, and as it is partial to grain of all kinds, to young turnip buds and leaves, also to the roots in which rooks or other birds have first pecked a hole, the amount of damage it does is very considerable. It also devours gooseberries, green corn, young clover, acorns, beech-mast, and wild fruit of most kinds. But the pigeon is not purely a pest to the farmer; after the harvest, when it resorts to the stubbles, it consumes an immense quantity of seeds of charlock and other noxious weeds.
In autumn and winter the number of wood-pigeons is greatly increased by the arrival of large flocks from the Continent; and at this season, and until March, it is not uncommon to see them congregated in thousands.
The wood-pigeon is the handsomest, as well as the largest, of the British doves, its dove-grey tints being singularly delicate, soft, and harmonious, and their effect heightened by the white marks and touch of iridescent colour on the neck. On the ground its motions are deliberate, and have a graceful dignity which contrasts strongly with the hurried, eager manner of the rock-pigeon and stock-dove. When startled from its perch it rushes out with great violence and loud clapping of the wings. Its flight is easy and powerful; and before alighting, when it sweeps swiftly and silently on its long, sharp-pointed wings through the glades of a wood, it sometimes has a singularly hawk-like appearance. Even the wild birds in the wood may be deceived by it, and thrown for a few moments into a violent commotion.
