Taxonomy

The chestnut-bellied rock thrush was formally described in 1832 by the Irish zoologist Nicholas Vigors under the binomial name Turdus erythogaster. [2] Unfortunaely the identical name had been used for a different species by the Dutch naturalist Pieter Boddaert in 1783. [3] [4] The chestnut-bellied rock thrush was described again in 1833 by the English naturalists William Jardine and Prideaux John Selby under the binomial name Petrocincla rufiventris. [5] They specified the locality as the "Himalayan region" but this was restricted to Shimla in Himachal Pradesh, India, by Sidney Dillon Ripley in 1961. [6] [7] The specific epithet rufiventris is Modern Latin meaning "red-bellied" from Latin rufus meaning "ruddy" or "rufous" and venter, ventris meaning "belly". [8] The chestnut-bellied rock thrush is now one of the 15 species placed in the genus Monticola that was introduced in 1822 by the German naturalist Friedrich Boie. The species is monotypic: no subspecies are recognised. [9]

Description

The chestnut-bellied rock thrush is 21–23 cm (8.3–9.1 in) in overall length and weighs 48–61 g (1.7–2.2 oz). The male has a blue-grey crown and upperparts with darker lores and throat. The undersides are deep chestnut. The female has dull grey-brown upperparts and scalloped slate-grey with buffy-white underparts. The eyering and the post-auricular patch are whitish-buff. [10]
