Range Description

Learn more about this article

Leptotila conoveri occurs on the east slope of the Central Andes of Colombia. It is known only from the valleys of the Coello-Combeima river system, near Ibagué, Tolima, and two valleys in the headwaters of the río Magdalena, Huila. However, of the latter two valleys, there are no records from one since 1952. The small number of records suggests that its population is small. It is fairly common at one site in Tolima3.

Habitat and Ecology
It occurs mainly in humid forest and bushy forest borders in the subtropical zone at 1,600-2,225 m, and possibly as high as 2,500 m. It has been found in secondary growth, with one record from a valley of coffee groves and secondary forest. Birds collected in Huila in March-April, and in Tolima in June, were in breeding condition.

Justification
This species is known from a very small number of locations and habitat fragmentation, loss and degradation are continuing within its very small range. The population is almost certainly very small, fragmented and declining. It is therefore classified as Endangered.

Population
Population estimate = 2.4-5.3 individuals/km2 x 436 km2 (45% EOO) = 1,046-2,311, i.e. best placed in band 1,000-2,499 (density range lower to upper quartile of five estimates for two species of forest congeners in the BirdLife Population Density Spreadsheet, as descibed as "fairly common" at one site).

Threats

Learn more about this article

Major Threats
Parts of the upper Magdalena valley have been converted to agriculture since the 18th century4 but, when the type-series was collected in 1942, the higher valleys of the Toche area, Tolima, were heavily forested. Since the 1950s, much of the original habitat in these valleys has been cleared and used for agriculture, including coffee plantations, potatoes, beans and cattle-grazing1,3. Mature secondary forest patches are now fragmented, and natural vegetation cover is judged to have been reduced to c.15% between 1,900 and 3,200 m1,3.

Conservation Actions

Conservation Actions
Conservation Actions Underway
It has not been recorded from any protected areas. However, an integrated conservation programme for the forests around the type-locality should benefit this and other threatened species in the area. Action for the Yellow-eared Parrot Ognorhynchus icterotis has increased public awareness and community involvement in conservation issues in the río Toche area, Tolima2, which should also benefit L. conoveri.

Conservation Actions Proposed
Evaluate forest cover in its range and follow-up with surveys of larger blocks to determine the current population and distribution1. Investigate the ecological requirements of this species, especially the degree to which it tolerates modified habitats. Protect a stronghold area, if found1.
