Saltmarsh Sparrow Song:


Nests of Saltmarsh Sparrows are made by females from grasses and reeds and often placed on a bed of cordgrass and held in place by the surrounding plants. They may also build a dome over the nest to protect and hide it.

Females lay up to six eggs, taking around twelve days to hatch and an additional ten days for the young to leave the nest.

Fun Fact:

Saltmarsh Sparrow nests are often submerged by the highest tides, which causes males to be promiscuous and non-territorial, so they can quickly breed again if the nest fails.
