 performed in sweeps high up in the air, but when migrating at change of season, or wandering as they often do in search of food, they usually arrange themselves in two lines, diverging from a leader. All the various species are social in their habits, and live in company with many varieties of shore birds. Even during the period of incubation the same disposition is manifest, the flocks keep together, not only in their winter quarters, but throughout the breeding season; some few species, however, are exceptions to this rule, and separate in pairs whilst rearing their young. The nests are usually placed upon trees growing in the water or on marshy ground, and are formed of twigs, fibres, blades of grass, and similar materials; it is not uncommon, however, for the breeding pair to avoid all labour by taking possession of an empty nest. The eggs are from three to six in number, and have the shell of uniform hue. It is uncertain whether both parents assist in the task of incubation; they both, however, testify great anxiety for their offspring, and tend them even long after they have joined the rest of the flock. The young birds attain their full strength but slowly, and do not undertake the cares of a family until they are two and in some instances three years old.

The FALCINELS (Falcinellus) constitute a group of the above birds, possessing a slender body, moderately long neck, thin, curved, and long beak, medium-sized foot, and somewhat broad, rounded wings, in which the second and third quills are the longest; the tail is short, the plumage thick, and the face bare.

THE GLOSSY IBIS.

The (Falcinellus igneus), a European representative of the above group, is of a brownish red on the throat, breast, belly, legs, and upper portions of the wings. The crown of the head is dark brown, shaded with red; the back, tail, and quills are brown, with a green or violet sheen. The eye is brown, the bare circles around it greenish grey; the beak dull dark green, and the foot greenish grey. During the winter the head and throat are black, and the feathers lower down of a lighter shade, with white edges; those on the upper part of the body exhibit a mixture of copper-colour and green; the under side is brownish. This species is from nineteen to twenty-three inches long, and from thirty-five to thirty-eight broad; the wing measures from thirteen to fourteen inches, and the tail three inches and a half.

The Glossy Ibis frequents the whole of Central Europe, a large portion of Asia, and Northern Africa, and visits the central and western portions of the latter continent. During its migration, it is met with in India in large numbers during cold weather, whilst in Egypt it remains throughout the year. In Central Europe it arrives about the end of April, and leaves again from August to September. It is reported to have even visited Great Britain. "The Ibis," says Montagu, "is adopted as part of the arms of Liverpool, and formerly, if not at present, stood conspicuous on the Guildhall in golden array. It was termed the 'Liver,' from which that flourishing town derived its name, and is now standing on the spot where the 'Pool' was, on the verge of which the Liver was killed." Aristotle records that the Glossy Ibis, or Liver, was called "Leheras," or "Jeheras," by the ancient Egyptians.

River-banks, edges of large tanks, djeels, swamps, and inundated paddy-fields, are the favourite resorts of these birds, affording them a plentiful supply of the mussels, fish, small reptiles, and similar fare, for which they wade deep into the water during the winter months; whilst in summer, on the contrary, they subsist principally upon larvæ, worms, and insects of various kinds, seizing their prey with great dexterity, even when upon the wing. They roost at night in beds of large reeds, and fly in flocks, which move with remarkable regularity, and generally assume the form of a wedge. The loud call of the Glossy Ibis is often uttered in flight and when alarmed. It is now fully ascertained that these birds breed in Europe, and we have to thank Löbenstein for an account of their nests, as seen by himself in the Donautiefländer. These nests were situated in a reed-covered marsh, and placed on
