These birds are common in dry fields and pastures, where their faint lisping song is heard throughout the day. Nest is usually a deep structure in a hollow in some dry field, and usually placed near some rock or suitable place where they can watch the locality for danger. Four eggs are laid; white, finely dotted with chestnut (.72 × .55).
