Distribution and habitat.
Their breeding habitat is open fields and prairie across southern Canada, the United States, Mexico and Central America, with a small endangered population in the Andes of Colombia and (perhaps only formerly) Ecuador. The northern populations migrate to the southern United States, Mexico, Central America and the Caribbean. Like many grassland birds, this bird's numbers have declined across many parts of its range, including a 98% drop in New York State.
Behaviour.
The nest is a well-concealed open cup on the ground under vegetation. They forage on the ground in vegetation, mainly eating insects, especially grasshoppers, and seeds.
Call.
This bird's song is a buzzy "tik tuk zee", resembling the sound made by a grasshopper. Unlike some other members of the Ammodramus family of sparrows, they will readily sing from open and exposed perches.
