Physical 

Seaside Sparrows have a robust, yet graceful, appearance. Sporting a dark streaked chest and flanks, they have a distinct grayish face with a sharp white throat. A noticeable feature is the yellowish streak just in front of their eyes. Males and females look similar, with an overall blending of grays and browns in their plumage. They usually measure about 4.5 to 6 inches in length.

Habitat

As their name suggests, Seaside Sparrows are inhabitants of the coastal salt marshes, predominantly found along the eastern and southern coasts of the United States. Their preferred habitats are dense marsh grasses, particularly where there’s a mix of Spartina grass.

Feeding 

These sparrows are omnivores with a varied diet. They primarily forage for insects, spiders, and small crustaceans among the marsh grasses. Seeds of marsh plants also make up a portion of their diet, especially in colder months.
