The SANDPIPERS (_Tringæ_) are known by their slender body, moderately long neck, small head, long pointed wings, in which the first quill exceeds the rest in length, and a moderate tail, either rounded or doubly incised at its extremity. The beak is either longer than, or as long as, the head, slender, compressed at the sides, with the culmen near the tip slightly depressed and enlarged. The slender bare foot is furnished, in most instances, with four toes; of these the three placed in front are long and entirely disunited, while the very small and delicate hind toe is raised too high to reach the ground. The thick compact plumage is principally a mixture of greyish brown and reddish yellow, but varies considerably according to the season, and age or sex of the bird; in the winter it is ashy grey above, white shaded with grey beneath. The colour of the sexes is nearly alike. Sandpipers are met with in all portions of the globe, but principally frequent its northern parts. Marine marshes on the sea-shore, or the borders of lakes and rivers, are the situations they prefer, visiting the temperate climates during the winter, and returning to the colder latitudes to spend the summer months. Their migrations take place in large parties, which fly by night or early in the morning. During the recess of the tide, they may be seen upon the sea-shore, seeking their food from the refuse of the ocean, or quietly and intently probing the sands in search of worms and shell-fish, and sometimes retreating rapidly before the advancing surge, and profiting by what the wave leaves on its retreat. In all their movements they display great activity, either when running rapidly and lightly on the fore part of their toes over the surface of the moist sand, when swimming in the water, or when winging their way with a varied, graceful, and rapid flight through the air. The voice of these birds is clear, piping, and resonant. All the various species are social and peaceful in their habits, and it is probable that the encounters in which they indulge at certain seasons of the year are as much in sport as in rivalry. The food of the Sandpiper consists of worms, small molluscs, insects, larvæ, and similar fare, but occasionally of delicate seeds. The four pear-shaped eggs are deposited in a dry hollow on the ground, which is slightly lined with a few blades of grass. The female alone broods; the young come forth covered with down, they at once leave the nest, and grow with great rapidity. * * * * * The CURLEW SANDPIPERS (_Limicola_) have a compact body, short neck, and small head; the beak is longer than the head, and only soft and flexible at its tip, which is broad, and curves slightly downward. The low, stout, bare foot is furnished with four toes. The wings are pointed, and have the first and second quills of equal length, and longer than the rest; the tail is short and pointed towards its centre. THE PIGMY CURLEW SANDPIPER.
