Seaside Sparrows are grayer than most sparrows, and they have a yellow spot in front of their eye. They are chunky birds with long bills.

  • Ammospiza maritimus
  • Length: 5.1-5.9 in (13-15 cm)
  • Weight: 0.7-1.0 oz (19-29 g)
  • Wingspan: 7.1-7.9 in (18-20 cm)


As you can guess, Seaside Sparrows are found along the coast in salt marshes. They live along the Gulf and Atlantic coasts of the US, and those that breed in the north of their range migrate south, but the rest remain all year.

Habitat And Diet

You can find Seaside Sparrows in marshes foraging for seeds, insects, and spiders. They also use their large bill for digging in the mud for tiny sea creatures.

Seaside Sparrow Call/Song:

A few notes followed by a buzz.


Nests of Seaside Sparrows are built by females in tall marsh vegetation from tightly woven grass. They also often build a cover from surrounding vegetation. They lay up to five eggs which take around two weeks to hatch and a further ten days for the young to leave the nest.

Fun Fact:

Young Seaside Sparrows cannot fly when they leave the nest, and they take a further week before they are confident flyers.
