The Long-tailed Meadowlark is distributed in Chile south of the Atacama and in Argentina south of Buenos Aires and along the foothills of the Andes. It is found in dry grasslands and pasture where there are shrubs and trees. It is often seen perching on shrubs and fence posts.

It has a long pointed bill, a long white supercilium which becomes red in front of the eye in the case of the male (seen in photos 1 to 3 and 6). It is red below with a black, incomplete breast band and has black on the flanks.
