It has a short conical bill, a streaked back and white tail with dark markings along its edges.
During the breeding season they move northward to their nesting grounds while during winter they migrate southwards towards Mexico and parts of US where temperatures are more favourable for survival.
They form flocks when migrating or searching for food which can contain up to 50 birds at any given time.
The diet of this species consists mainly of seeds but also includes insects such as grasshoppers, beetles etc., making them an important part of the local ecosystem by controlling insect populations.
