Wikipedia Abstract

The saltmarsh sparrow (Ammodramus caudacutus) is a small American sparrow. 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". Their breeding habitat is salt marshes on the Atlantic coast of the United States from southern Maine to Virginia. The nest is an open cup located above the high tide line. Males compete for females but do not defend territories. Only females raise the young.
