Wikipedia Abstract

The vesper sparrow (Pooecetes gramineus) is a medium-sized American sparrow. It is the only member of the genus Pooecetes. Adults have light brown upperparts and light underparts, both with darker streaking. They have a white eye ring and a long dark brown tail which shows white outer feathers in flight. Their 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. These birds migrate to the southern and central United States and Mexico.
