The Dickcissel, Spiza americana, is a small seed-eating bird in the family Cardinalidae. Their breeding habitat is fields in mid-western North America. These birds migrate in large flocks to southern Mexico, Central America, and northern South America. Although this bird was originally quite common along the Atlantic coast of the United States, only small numbers occur there now.

These birds have a large pale bill, a yellow line over the eye, brownish upper parts with black streaks on the back, dark wings, a rust patch on the shoulder and light under parts. Adult males have a black throat patch, yellow breasts and gray cheeks and crown. Females and juvenile birds are brownish on the cheeks and crown.

Dickcissels forage on the ground or in fields. They mainly eat insects and seeds. Outside of the nesting season, they usually feed in flocks. They can consume mass quantities of cultivated grains and are considered pests in some regions by farmers.
