The male Godwit is always smaller than the female. Two species of this bird are known—the Black-tailed Godwit (Limosa ægocephala), and the Barred-tailed Godwit (Limosa rufa).

The Curlew (Numenius), [Fig. 134], is remarkable for the immoderate length of its bill, which is slender, curved, and round from end to end. Its wings are medium-sized, and tail short. Its plumage is a mixture of grey, russet, brown, and white. It derives its name from the plaintive, melancholy cry which it utters when it takes flight.

These birds frequent the sea-coast and the vicinity of marshes, feeding on worms, water-insects, and small mollusks. They plunge their bills into the ground, to a small portion of which they communicate a vibratory movement; the worms, disturbed in their subterranean dwellings, come up to the surface, and are immediately swallowed.

The gait of the Curlews, generally speaking, is grave and measured; but if any one disturbs them previous to taking wing, they begin running with astonishing rapidity. They are capable of a prolonged flight, but do not generally venture far into the interior of the country; it is on the coast they are always most abundant. They live together in numerous flocks, except during their breeding-time, when they isolate themselves in order to build their nests in some dry place among the grass. The female lays four or five eggs. The young ones run about to seek their food as soon as they leave the shell, and receive no attentions from their parents.

The Curlew is of a wild and timid nature. Nevertheless, in Senegal, they have been domesticated; to no great advantage, it is true, as their flesh always retains a very marshy flavour.

Curlews abound all over the globe. They are very common in France, where they arrive in the month of April, leaving again in August, although sometimes they pass the winter on the coast. Of their sojourn in the British Islands the same may be said. A beautiful variety of the Curlew is found in America. In shooting them the great difficulty is to get within range. The sportsman, if well secreted, may occasionally succeed in obtaining a shot at Curlews by imitating their call.

The Ibis has a long bill, curved in the direction of the ground, almost square at its base, and rounded towards the termination; the head and neck are bare. It has four toes; the three front ones are united at the base by a membrane; the whole length of the back toe rests upon the ground.

These birds are inhabitants of the warm regions of Africa, Asia, and America; only one species, the Green Ibis, being found in Europe. They are to be met with in companies of seven or eight together, in moist and marshy grounds, and on the banks of large rivers, where they catch the worms, water-insects, and small mollusks which form the principal part of their food. They also crop young and tender aquatic plants. Their nature being mild and peaceable, they do not keep shifting about with that petulance which characterises some of the Grallæ, but have been observed to remain for hours in the same place engaged in digging into the mud which conceals their small prey. Like nearly all the other birds of this order, they migrate every year, and undertake long journeys from one continent to another. They are monogamous, each pair swearing, as it were, eternal fidelity to one another, and death alone can sever the bonds fortified by affection and habit. They usually build their nests on lofty trees, but sometimes on the ground; the female lays two or three whitish eggs, which hatch in from twenty-five to thirty days.
