There are 13 species of leafbirds.  They are found in forests and woodlands across India and Southeast Asia.

Most leafbirds are bright green with yellow, blue, or black markings that help them blend in with the leaves. Males are usually more brightly colored than females. They have brush-tipped, forked tongues that help them drink nectar from flowers. They also eat insects, spiders, fruit, and berries.

During the breeding season, males sing loudly and perform short display flights to attract a mate and defend their territory. Leafbirds usually build small, cup-shaped nests in trees or shrubs. The female lays 2–3 eggs and does most of the incubation, while the male often feeds her and later helps care for the chicks.
