Taxonomic Changes
The differences within the genus Mirafra are often very subtle and confusing with many differences apparent only when specimens are examined in hand.
The Bengal Bush Lark was earlier classified into several races, the Bengal race assamica and the Madras race affinis. These were subsequently split, on the basis of diagnostic song and display characters, into the Jerdon's Bush Lark (Mirafra affinis) and assamica in the strict sense. Mirafra (assamica) assamica is dark-streaked grey above, and buff below, with spotting on the breast and behind the eye. The wings are rufous. Jerdon's Bushlark has paler, greyish-brown underparts. The song of Jerdon's Bush Lark is a dry rattle given from its perch, while that of M. (a.) assamica is a repetition of thin disyllabic notes, delivered in a song-flight.
