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. See the distribution map at xeno-canto. 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.
