[AS.] A small bird, with small legs and weak feet, but with long, pointed wings and a forked tail, which are both favorable to switf flying. It flies at a rate of from 60 to 90 miles an hour, and delights in circling round places where insects abound, upon which it feeds. The house-martin or town swallow fixes its mud nest under the eaves of houses. The sand-martin with its tiny beak bores holes in sandstone rocks, where it makes its nest at the farthest extremity with loose hay and a few goose feathers. There are a number of American species, a common one being the barn-swallow. The nest of the esculent swallow, which inhabits Ceylon and Sumatra, is much valued by the Chinese. It consists of seaweed, which the birds swallow and mix with their saliva, and then deposit in layers round their nests, and the whole is hardened by the air. The nests are glued on rocks or inside caverns, near the sea-shore. When boiled, these nests, which are in reality a fine gelatine, yield a good quality of glue or jelly, which is made into soup. (See Swift.)
