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.[2]
The common name commemorates the surgeon-naturalist Thomas C. Jerdon.[3]

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.[4]
Range
M. affinis has a large range in south-east India and Sri Lanka, with an estimated global extent of occurrence of 100,000-1,000,000 square kilometres.[5]
Habitat
It has proven adaptable to a variety of open habitats up to a maximum elevation of 1500 m. Some of these are forest perimeters, rocky scrubland, scrubby hill meadows and clearings in open-type forests, shrub-edged unused croplands, and thickets of bamboo.[5]
Habits
Its song-flight is indistinguishable from that of Indian bush lark, However, unlike the aforementioned species, Jerdon's bush lark often perches on trees and wires.[4]
