Pittas are medium-sized by passerine standards, at 15–25 cm (5.9–9.8 in) in length, and stocky, with longish strong legs and long feet. They have very short tails and stout, slightly decurved bills. Many, but not all, have brightly coloured plumage. These are fairly terrestrial birds of wet forest floors. They eat snails, insects and similar invertebrate prey. Pittas are mostly solitary and lay up to six eggs in a large spherical nest in a tree or shrub, or sometimes on the ground. Both parents care for the young. migratory
