The sheldrake is one of the largest and handsomest of its kind, and although rare as a resident bird, I have frequently found its nest in rabbit burrows on the shores of Morecambe Bay. It is at all times one of the most distinctive of the ducks with its bright and well-defined chestnut and white plumage. The head and neck are black, but this glows with an iridescent green. Naturalists do not consider this a true duck, but from structural modifications as a connecting link between the ducks and geese. It usually breeds on a plateau commanding the sea, and when approaching its nest it plumps right down to the mouth of the hole. Its creamy white eggs are large and round, eight to twelve being usually found in the burrow. For a day or so after the young are hatched they are kept underground, and immediately upon emerging are led down to the tide. I have not unfrequently taken the eggs from the sand-hills and hatched them under hens--a quite successful experiment up to a certain point. The young seem to be able to smell salt water, and will cover miles of land to gain it. If, however, the distance prove impracticable they will surely leave in autumn when the migratory impulse is strong upon them. This instinct is particularly marked in all sea-fowl, and wild swans, geese, and ducks call loudly to their farm cousins as they pass over. There is a great wildness about the clangour and cries of migratory fowl, coming as it does far up in the wintry sky. Reverting to the breeding of the shelduck, the parents have been observed conveying the newly-hatched young to the sea on their backs when the nest has been far inland. In Holland recesses are cut in the dunes and sand-hills so as to encourage the birds to breed, and each morning the nests are visited and the eggs collected. Ordinarily not more than a dozen eggs are laid, but under this system as many as thirty are produced by a single duck. After the 18th of June the persecution ceases and the birds are allowed to hatch in peace. Most of the nests are lined with fine down little inferior in quality to that of the eiders, this too becoming a commercial commodity.
