Alondra Arbustiva Bengalí

Identificación

The Bengal bush lark is short-tailed and has a strong stout bill. It is not as long as the skylark, measuring about 15 centimetres in length. It is dark-streaked grey above, and buff below, with spotting on the breast and behind the eye. The wings are rufous.<p>The song of the Bengal bush lark is a repetition of thin disyllabic notes, delivered in a song-flight.

Taxonomía

The differences within the genus Mirafra are often very subtle and confusing with many differences apparent only when specimens are examined in hand.<p>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. Formerly, both the Burmese bush lark and Jerdon's bush lark were considered subspecies of the Bengal bush lark (as M. a. microptera and M. a. affinis respectively) until split to form a separate species. The alternate name "rufous-winged bush lark" may also be used to describe the red-winged lark. Another alternate name for the Bengal bush lark is the rufous-winged lark.
