 were, on my taking out the egg to examine it, the little things, which could not have been out of their shells more than an hour or two, set off out of the nest with as much celerity as if they had been running about for a fortnight.

The Common Sandpipers appear in Central Europe towards the middle of April or beginning of May, and by July have reared their young, and commenced flying about the country previous to leaving it, which they do about the second or third week in September. Their migrations are carried on in small parties of from six to twenty individuals, and take place at night; the birds descending, when day breaks, to seek for food upon a river-bank or similar locality, and usually sleeping for a few hours at noon. Should the chosen spot prove attractive, it is not uncommon for these parties to remain for several days before resuming their journey. Sandy localities, covered with bushes or reeds, are the favourite resorts of these birds; the latter affording a safe retreat in case of danger or alarm, to which their timid, cautious disposition renders them peculiarly susceptible. Naumann mentions that a garden-seat placed about four feet above the surface of a pond in his garden, and thickly overhung with branches and surrounded by bushes, was regularly selected as a sleeping-place by all the Sandpipers that crossed his grounds during their migrations. The movements of this species are in many respects unlike others of its kind; it stands erect, walks with an active tripping step, and constantly whips its tail while in motion. The flight is swift and easy, but, unlike that of most other Sandpipers, is seldom carried on at any great height in the air, the bird usually sweeping so close over the surface of the water as almost to wet its wings; only when finally quitting a spot does it rise far from the earth, and rapidly seeks another hunting ground. If much alarmed, it betakes itself to the water, and either swims or dives to a safe distance from the place of danger. Although remarkably shy, this species appears readily to distinguish those who are likely to molest it; and exhibits such adroitness in seeking concealment as frequently to escape even from the clutches of a Sparrowhawk. It seldom associates with other shore birds; and the breeding season once over, the pairs usually separate, and, like their companions, go their own way, only joining their fellows if the chosen spot be favourable for food, without any reference to each other's presence. As the season for incubation approaches, the male birds exhibit much excitement, and display themselves to the greatest advantage, darting through the air in zigzag lines, and trilling forth their call in the hope of attracting the attention of their desired mates. This call, which commences in a low tone, gradually swelling and dying away, is exchanged at other times for a high, clear, resonant, piping note. The nest is formed of twigs, reeds, stubble, or dry leaves, and is placed at a safe distance from the water, beneath a sheltering shrub or bush. The pear-shaped eggs vary somewhat in size and form, and have a delicate, glossy, reddish yellow shell, marked and spotted with various shades of brown. Both sexes brood, and exhibit great uneasiness when disturbed; should they be deprived of an egg they at once desert their post. The young are hatched in about a fortnight, but remain a little longer under the mother's wing, after which they are led forth to seek their own food, and in four weeks are fully fledged and self dependent. The parents display much anxiety for the safety of their little family, and, if molested, express their alarm by loud cries; whilst the young at once hurry to a place of concealment, and remain so quiet as to render their discovery almost impossible without the aid of a dog. Insects, larvæ, and worms form the usual fare of the Common Sandpipers, and in search of these they often display most amusing dexterity, gently approaching such active-winged prey as flies and gnats, with every sign of extreme caution, and then snapping up the desired morsels by an almost unerring stroke.
