WIGEON.
Of all the more typical birds in this sub-family, the present species, the Anas penelope of naturalists, is by far the best known along the coast. The male bird is a very pretty and conspicuous one, in his beautifully pencilled back and flanks, and distinguished from afar by his bright buff forehead and crown, and white wing coverts. The female is much less showily coloured. The Wigeon arrives upon our seaboard, from the Arctic regions, in vast numbers every autumn, and from that time forward to the following spring resides with us. This autumn migration of the Wigeon begins late in September, and lasts well on into November. The birds begin to leave us again in March, and most have departed by the end of the following month. The Wigeon, whilst with us, is one of the most gregarious of the Ducks, and flocks of vast size may sometimes be observed in our shallower seas close inshore, in estuaries and bays, but perhaps more frequently further out at sea. These birds obtain most of their food at night in such localities where they are subjected to much persecution, as often happens, for their flesh is valued as an article for the table, coming landwards at dusk, and retiring to the open sea at dawn. The flight of this species is rapid, yet almost noiseless, and the bird may sometimes be seen gliding down from the air to the water on stiff and motionless wings, but flapping them rapidly just as it drops, tail first, into the sea. Its note is highly characteristic, a shrill, far sounding mee-ow, or wee-ow. The food consists of grass, buds, and leaves of aquatic plants, grass wrack, crustaceans, and molluscs. Many Wigeons are caught in the flight-nets on the Wash, a locality which is, or used to be twenty years ago, a favourite resort of this Duck.
A few Wigeons remain in our Islands to breed, frequenting the northern counties of Scotland, including the Orkneys and the Shetlands, but the vast majority return to the Arctic regions to do so. Its favourite nesting-places are scrubby woodlands, swamps, and heaths, clothed with coarse herbage, studded with lakes and tarns, and intersected by streams. Although not gregarious at this period, the numbers of nests found scattered over a small area, suggests at least a social tendency. The nest is usually made close to the water-side, amongst heath or grass, or sheltered by a little bush, and is made of dry herbage and leaves, warmly lined with down plucked from the body of the female. The six to ten eggs are cream- or buffish-white, smooth in texture, but with little gloss. These are laid in May.
