Areale e habitat

The Tolima dove was believed to be limited to the eastern slope of Colombia's central Andes in Tolima and Huila Departments. In 2014 it was discovered in Cundinamarca Department in the eastern Andes. It mostly inhabits the interior and edges of humid subtropical forest, in an elevation range of 1,200 to 2,500 m (3,900 to 8,200 ft). However, in the canyon of the Combeima River it is found in disturbed areas including coffee plantations and near human habitation.

The Tolima dove has been reported as feeding mainly on Bocconia frutescens seeds but nothing else is known about its diet or foraging habits.<p>Observations of Tolima doves in breeding condition, eggs, and nestlings indicate a nesting season that extends at least from March to September. It builds a shallow bowl nest of heavy twigs in bushes or small trees, usually no more than 2 m (6.6 ft) above the ground. The clutch size is two eggs.<p>The Tolima dove's song is "a single slightly over-slurred note “wooOOOooo”, with a clear emphasis in the middle."
