The food of the Lapwing consists largely of earth-worms, to which are added slugs, insects and their larvae, and small crustacea.

The Spoon-bills, however, shew an exception to the sharpness of this organ; and the Curlews to its straightness. The wings are, in general, well developed, and some of the genera are birds of soaring and power-
