Ammospiza caudacuta

Appearance

Male and female sparrows have the same coloration and markings. The saltmarsh sparrow has an orange face with gray cheeks under its eyes, triangular dark patches by its ears and a black stripe on the top of its head stretching from its beak to its back. They have a pale chest with brown sides streaked with black. They have an elongated conical bill and a much shorter tail than other sparrows.

Feeding

Saltmarsh sparrows feed exclusively on food found in tidal salt marshes. They will catch bugs including grasshoppers, caterpillars and beetles to feed to young. During the winter months they will also feed on the seeds of marsh plants.

Predators

The main threat to the saltmarsh sparrow is flooding from high tides during nesting. Snakes, birds and marsh mammals are all predators of adult and immature sparrows.

Voice

The saltmarsh sparrow has a quiet song including a variety of high-pitched trills and clicks.

Reproduction and Life Cycle

Saltmarsh sparrows breed in the tidal salt marshes along the east coast from the Chesapeake Bay up to Maine. Males and females will have multiple mates and one brood will often have multiple male parents. Males are not involved in raising chicks or maintaining the nest. Females will lay between two to six eggs.
