#318 Vesper Sparrow (Pooecetes gramineus)

17 January 2021

Breeding habitat is open grassy areas across most of North America. The nest is an open cup on the ground under a clump of grass. Migrate to the southern and central United States and Mexico.

Forage on the ground, mainly eating insects and seeds. Outside the nesting season they often feed in small flocks.

The male sings from a higher perch, such as a shrub or fencepost, which indicates his ownership of the nesting territory. The musical song begins with two pairs of repeated whistled notes and ends in a series of trills, somewhat similar to that of the song sparrow.

Numbers are declining in the eastern parts of its range due to habitat loss.
