Indian Pitta (Pitta brachyura) The 20 cm Indian Pitta is a small bird which occurs in many parts of the country. Its brilliant colors light up the dark and wet forest understory in which it leads a shy existence. Pitta is derived from Telegu which means a small bird. The chirp of these birds can generally be heard in the morning and in the dusk. Because of the timing of their calls, these birds are also called as six-o-clock birds in Tamil.
