VU White-throated Bushchat  Saxicola insignis

2009 IUCN Red List Category (as evaluated by BirdLife International - the official Red List Authority for birds for IUCN): Vulnerable

Justification This poorly known chat has a small, declining population as a result of loss of its wintering grassland habitats to drainage, conversion to agriculture, overgrazing, flooding, and thatch harvesting. These factors qualify it as Vulnerable.

Family/Sub-family Muscicapidae

Species name author Gray, 1846

Taxonomic source(s) Sibley and Monroe (1990, 1993)

Identification 17 cm. Large chat. Adult male has white throat and sides of neck. White primary coverts, patch at base of primaries, inner median and greater coverts and at base of tertials and secondaries. Black crown, ear-coverts and mantle with rufous-brown fringes. Rufous-orange underparts becoming pale on belly. Female has buffish supercilium, pale throat and buffish crown and mantle. Similar spp. Common stonechat S. torquata is smaller, lacks white primary coverts and patch at base of primaries and has dark throat. Voice Metallic teck-teck.

Range & population Saxicola insignis breeds very locally in the mountains of Mongolia and adjacent parts of Russia. It has been recorded on passage in northern and western China and Tibet1, and winters in the terai of northern India and Nepal, with one spring record from Bhutan. Although once common, it is now rare and local in its wintering range. In 1998, the wintering population in Nepal was estimated at just 110 individuals. Little is known about populations in its breeding grounds.

Ecology: It breeds (c.June) in alpine or subalpine meadows and scrub in mountains. It winters (October-May) in wet and dry grasslands, reeds and tamarisks along riverbeds, and also in sugarcane fields, in open terrain below 250 m. On migration, it occurs up to 4,500 m. Optimum grassland habitat appears to comprise a mosaic of disturbed (burned or grazed) and undisturbed habitat, although it is absent from apparently suitable sites.

Threats The major threat appears to be rapid and extensive loss and modification of grasslands in its wintering grounds, as a result of drainage, conversion to agriculture (although it appears to have partially adapted to sugarcane), overgrazing, grass harvesting for thatch production and inappropriate grassland management within protected areas. Recent heavy flooding in the valley of the Brahmaputra, compounded by forest destruction in its catchment, has destroyed further suitable habitat.

Conservation measures underway CMS Appendix II. Wintering populations regularly occur in several protected areas, including Kaziranga, Corbett and Manas National Parks, India, and Lumbini Crane Sanctuary, Chitwan National Park and Sukla Phanta Wildlife Reserve, Nepal, the latter site supporting perhaps the highest recorded concentrations.

Conservation measures proposed Conduct further surveys for the species across its breeding and wintering range to identify important sites and potential threats. Extend, upgrade and link (where possible) existing protected areas, and establish new ones, in order to adequately conserve remaining tracts of natural grassland. Promote grassland regeneration. Control livestock-grazing in relevant protected areas. Promote widespread conservation awareness initiatives focusing on sustainable management of grassland to maximise both thatch productivity for local people and available habitat for threatened grassland birds.
