Justification of Red List Category
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.
The global population size has not been quantified, but the species is described as common below 900 m (Cheke et al. 2001).
The population is suspected to be in decline owing to ongoing habitat destruction.
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.
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.
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.
