Seaside Sparrow Ammospiza maritima

Sign in to see your badges



The darkest sparrow found exclusively in wet saltmarshes with tall grass. Shares habitat with Saltmarsh and Nelson's Sparrows but Seaside is plainer and grayer overall. Plumage differs slightly among populations: Gulf Coast birds brighter, southern Florida birds show more distinct streaking below, Atlantic birds dullest. All populations have a contrasting white throat, yellow in front of eye, and a long bill. Perches conspicuously when singing, otherwise secretive, especially in winter. Rougher, buzzier song than Nelson's or Saltmarsh Sparrows: a few harsh introductory notes followed by a raspy sigh.
