(antbirds), a family of birds of the order Passeriformes. Body length, 9.5–36 cm. The bill is laterally compressed and sometimes hooked at the tip. Terrestrial species are long-legged, and arboreal species short-legged. The males are garbed in contrasting colors, often with white, black, or red patches or transverse stripes; the females have monochromatic coloration. There are 222 species of antbirds, distributed from southern Mexico to central Argentina. They live hidden in forests or thickets. Antbirds build their nests in shrubs or, less frequently, on the ground. A clutch contains two or, rarely, three eggs, which are incubated for 14—17 days. Antbirds feed principally on insects, mainly ants.
