White-throated Flowerpecker Dicaeum vincens

Justification
This species has a small range within which habitat is continuing to deteriorate in extent and quality. However, the range is not yet severely fragmented or restricted to few locations. For these reasons, the species is classified as Near Threatened.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Identification
10 cm. A stout-billed flowerpecker. Male has bluish-black upperparts, white throat, upper breast and undertail-coverts, yellow lower breast and belly, and white tips to outer tail feathers. Female has blue-grey crown, ear-coverts and nape, becoming dark olive on mantle and back. Juvenile resembles female but duller with olive-brown upperparts, olive-yellow rump and centre to belly. Voice Call a harsh dzit. Song a high-pitched, metallic ptit ptit ptit ptit tsi or tit tit tit tit tit tit and also a high, thin, rapid psee-psee-psee-psee-psee-psee-psee.

Distribution and population
This species is endemic to Sri Lanka, where it is confined to the wet zone in the south-west of the island, with a few records from the intermediate zone. Although it remains locally common and survives in many forest blocks it probably has a declining, increasingly fragmented population of several tens of thousands of individuals.

Population justification
The global population size has not been quantified, but the species is described as common below 900 m (Cheke et al. 2001).

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction.

Ecology
It is mainly confined to lowland and foothill tall, moist forest up to 2,300 m. It has recently been recorded from disturbed sites close to primary forest probably because of the abundance of fruiting and flowering shrubs, on which it feeds, in such secondary habitats. Observations of birds crossing large forest openings and gaps between forest patches, suggest it may be able to move between forest blocks.

Threats
The main threat is the extensive clearance and degradation of forests, particularly in the wet zone, through logging, fuelwood collection, conversion to agriculture and tree plantations, gem mining, settlement and fire. Some protected forests continue to be degraded and suffer further fragmentation.

Conservation Actions Underway
It is legally protected in Sri Lanka. A moratorium was passed in 1990 to protect wet zone forests from logging. It occurs in several national parks and forest reserves, most notably Sinharaja National Heritage Wilderness Area and Peak Wilderness Area. A survey of the biodiversity of 200 forest sites was carried out from 1991-1996. Conservation Actions Proposed
Carry out a comprehensive survey in order to clarify its distribution and status and to produce management recommendations for this species in conservation forests and other protected areas. Encourage protection of remaining important areas of forest holding this and other threatened species, including proposals to designate conservation forests, and ensure their effective management. Research its ecology, particularly the effects of forest fragmentation on its population and distribution. Maintain the current ban on the logging of wet zone forests. Promote programmes to create awareness of the value of biological resources amongst local communities.
