Saltmarsh Sparrow

Ammospiza caudacuta

A small, secretive New World sparrow with a buffy-orange face, uniquely adapted to spend its entire life cycle in the tidal salt marshes of the Atlantic coast.

What it sounds like

A faint, wheezy, and hissing song that sounds like a whispered, scrambled 'te-shshshsh-pt-shsh'.

Field notes

  • It is the only terrestrial bird species in North America that lives exclusively in salt marshes throughout its entire life cycle.
  • Females often synchronize their nesting cycles with the lunar calendar to ensure chicks fledge between high spring tides.
  • The species is non-territorial and highly promiscuous, with a single clutch of eggs often sired by multiple different males.
  • They possess specialized kidneys and salt glands that allow them to survive while consuming brackish water and saline-rich invertebrates.
  • Due to sea-level rise and habitat loss, their population is declining by approximately 9% annually, putting them at high risk of extinction.
Habitat
High marsh zones frequently flooded by tides, specifically areas dominated by Spartina patens and Juncus gerardii.
Range
The Atlantic coast of North America, breeding from Maine to North Carolina and wintering from New York to Florida.
