Pitta \Pit"ta\ (p[i^]t"t[.a]), n. (Zool.) Any one of a large group of bright-colored clamatorial birds belonging to Pitta, and allied genera of the family Pittid[ae]. Most of the species are varied with three or more colors, 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. [1913 Webster]
