Saltmarsh sparrow

The saltmarsh sparrow is a small American sparrow found in salt marshes along the Atlantic coast of the United States. At one time, this bird and the Nelson's sparrow were thought to be a single species, the sharp-tailed sparrow. Because of this, the species was briefly known as the "saltmarsh sharp-tailed sparrow."

This bird's numbers are declining due to habitat loss largely attributed to human activity.
