Habitat and Distribution
Their breeding habitat is grasslands and prairie, also pastures and hay fields. The bird is a permanent resident in much of its range, though most northern birds migrate southwards in winter. In Central and South America, they tend to be limited to the eastern (Atlantic) side of the continent but recently the range is expanding towards the Pacific western side in agricultural-type areas.
These birds forage on the ground or in low vegetation, sometimes probing with its bill. They mainly eat arthropods, but also seeds and berries.
Nesting occurs throughout the summer months. The nest is also on the ground, covered with a roof woven from grasses. There may be more than one nesting female in a male's territory.
Calls and Songs
The song of this bird is of pure, melancholy whistles.
