Jerdon's bush lark : ウィキペディア英語版 | Jerdon's bush lark
Jerdon's bush lark (''Mirafra affinis'') is a lark of the open countryside found in southern India and Sri Lanka. This species was earlier considered a subspecies of the Bengal bush lark (''M. assamica''). However recent studies of differences in call and distribution have led to it being treated as a full species. The common name commemorates the surgeon-naturalist Thomas C. Jerdon. ==Description==
''M. affinis'' has arrowhead like spots pointing upwards on the breast. It is very similar to the Indian bush lark (''M. erythroptera'') but has buffy lores, less white behind ear coverts, darker centre to wing coverts and central tail feathers. Dark centres of primary coverts are prominent, and wing panels are duller and rufous. In the southern Western Ghats, the race ''ceylonensis'' is darker and more rufous on the underside and has a longer bill.
