Seaside sparrows are brown birds with a dark plumage that inhabit tidal saltmarshes with abundant and varied vegetation. This habitat is helpful for both their nesting and dietary requirements. They are quite territorial of their breeding areas but the subspecies are found grouped together in few places. They are found in a range of places from northeast Florida to North Carolina. They are also found in the marshes of the Atlantic Coast and along the Gulf Coast to Texas.

Due to habitat loss caused by an increase in sea levels, damage to vegetation distribution, and introduced contaminants in marsh areas of their breeding habitat caused by human activities, this bird is at risk. The U.S. Fish and Wildlife Service and other wildlife management and conservation organizations are putting efforts in to map and protect all the at-risk subspecies of this bird.

The seaside sparrow (Ammospiza maritima) has many subspecies that each have subtle differences. The dusky seaside sparrow, Scott's seaside sparrow, and the Cape Sable seaside sparrow are all seaside sparrows.

How do they reproduce?

The seaside sparrow reproduces by sexual reproduction. They partner for breeding in springtime. The male first approaches the female with a song, and the female reciprocates with the same song. After this courtship ritual, the female builds a nest while the male guards the territory. Males have special songs to alert other males of their nesting territory and to chase away any intruders. A brood consists of two to five eggs, and there may be two broods in a season. Both breeding partners incubate the eggs in the nest, which hatch in two weeks. The baby birds fly off after a month to be on their own.

According to the IUCN Red List, the conservation status of a Cape Sable seaside sparrow (Ammospiza maritima mirabilis) is Endangered. The dusky seaside sparrow (Ammospiza maritima nigrescens) is now extinct.
