Wikipedia Abstract

The African green pigeon (Treron calvus) is a species of bird in the Columbidae family, and one of 5 green pigeon species in the Afrotropics. As with others in their genus, they frequent tree canopies where their parrot-like climbing ability enable them to reach fruit, but rarely also forage on the ground. The species has a wide range in Sub-Saharan Africa with around 17 accepted races.Adult birds have maroon shoulder patches (olive in immatures) and rufous undertail coverts.
