(Science: ornithology) Any one of a large group of bright-coloured clamatorial birds belonging to Pitta, and allied genera of the family Pittidae. most of the species are varied with three or more colours, such as blue, green, crimson, yellow, purple, and black. They are called also ground thrushes, and old world ant thrushes; but they are not related to the true thrushes.
The pittas are most abundant in the East Indies, but some inhabit southern asia, Africa, and australia. They live mostly upon the ground, and feed upon insects of various kinds.
