About These Birds
Sri Lanka Woodpigeon
Sri Lanka Woodpigeon (Columba torringtoniae) — 35–38 cm. Dark purplish-brown; grey head; chequered black-and-white neck patch; purplish underparts. Endemic to Sri Lanka in montane forest at 900–2,200 m. Frugivore. Vulnerable; restricted to the island's central hill forests.
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
