Sri Lanka Wood-Pigeon Columba torringtoniae

Large, plain gray pigeon with conspicuous black-and-white stripes on the nape. Underparts flushed mauve. Inhabits upper levels of forests and densely wooded areas in the hills and mountains, where occurs in pairs or small flocks. Combination of black-and-white neck markings and plain, unmarked, dark gray upperparts identifies this species from all other pigeons on Sri Lanka. Vocalizations include a single, deep “wooo”, and also an owl-like, double note “woo-oo”.
