About These Birds

Sao Tome Olive-pigeon

Sao Tome Olive-pigeon (Columba thomensis) — 40–45 cm. Large; dark purplish-grey; yellow orbital skin; spotted wing coverts. Endemic to São Tomé Island in dense forest. Frugivore. Vulnerable due to ongoing deforestation of São Tomé's lowland forest.

African Collared-dove

Small dove, 26–29 cm, pale pinkish-grey with a black hindneck collar and white tail corners. Native to arid zones of sub-Saharan Africa from Senegal to Somalia and south to Tanzania. The ancestor of the domesticated Barbary Dove (ring-necked dove). Granivore of grass seeds and small grains in dry savanna, farmland, and desert edge. Least Concern.
