• Brownish upperparts with gray on the crown and nape, and a grayish-buff breast with dark streaks
• Dark face with gray cheeks and a white throat, featuring a small yellow streak just above the eye
• Short, pointed tail

Habitat

Breeding habitat consists of salt marshes on the Atlantic and Gulf coasts of the United States, ranging from southern New Hampshire to southern Texas. Nests are open cups built in tidal reeds and Spartina grasses, while feeding areas are often located some distance away from nesting sites.

Diet

These birds forage on the ground or in marsh vegetation, sometimes probing in mud. Their diet mainly consists of insects, marine invertebrates, and seeds.
