features

The Tolima pigeon reaches a size of 22.5 to 25 cm. The skull is blue-gray or dark gray, the throat is white. The rear neck is wine colored with a purple sheen. The upper coat is wine-colored gray with a purple sheen. The rest of the top is dark gray with a purple sheen. The wings are brownish. Underbust and belly are colored yellow-brown and contrast sharply with the wine-pink colored upper breast. The under tail coverts are white, the under wings are chestnut colored. The tail is slate-colored. The outer control feathers have white tips, which are not as wide as those of the sympatric white-forehead dove ( Leptotila verreauxi ).

Existence and endangerment

BirdLife International classifies Tolimataube as "high risk" ( endangered ), and estimates on the stock 600-1700 adult birds. The main threat comes from habitat loss. Parts of the upper Río Magdalena valley have been converted into agricultural land since the 18th century. The terra typica , the higher valleys of the Toche region in the province of Tolima , was still heavily forested when the Tolima dove was discovered in 1942. Since the 1950s, many of these valleys have been deforested and used for agricultural land, including coffee plantations, potato and bean cultivation, and cattle grazing. Since 1952 the Tolima pigeon has not been detected in two valleys of the headwaters of the Río Magdalena in the Departamento del Huila . The old secondary forest plots are fragmented and the natural vegetation has decreased to around 15 percent at altitudes between 1,900 and 3,200 m. The Tolima pigeon prefers the Quindio wax palm ( Ceroxylon quindiuense ) as a breeding tree, which is endangered by deforestation.
