This grassland bird has a wedge-shaped tail longer than half its body. It searches among grasses for insects and defends a territory as a breeding pair.
It is about 20 cm long, and its long tail accounts for more than half that length. The head, back, and wings are streaked in black, and the face is grayish. Juveniles have sulfur-yellow eyebrows and underparts.
It searches for insects on the ground and among grass stems. During breeding, birds live in pairs and males drive other males of the same species out of their territory.
Males sing from grass tops or exposed shrub branches. When perched birds partly spread the tail, its feathers become progressively shorter from the long central pair toward the sides.
The adult bill is yellowish with a black upper ridge. The legs are yellowish or pinkish.
