Vesper Sparrow
Pooecetes gramineus
| Conservation status | Has declined seriously in numbers in some parts of the East, probably owing to loss of habitat. In the West, still widespread and common. |
|---|---|
| Family | New World Sparrows |
| Habitat | Meadows, fields, prairies, roadsides. At all seasons, favors open grassy or weedy fields, often in rather dry situations with much open soil. May be in weedy roadsides, gravel pits, high mountain grasslands, stubble fields, grassy areas just above sandy beaches. Often breeds where there are a few taller plants for use as song perches. |

Feeding Behavior
Forages mostly or entirely on the ground, often on bare soil between grass or weed clumps. Except during nesting season, often forages in small, loose flocks.
Eggs
3-4, sometimes 2-6. Whitish to pale greenish white, blotched with brown and gray. Incubation is mostly by female, about 11-13 days. When disturbed at the nest, the female may flutter away as if injured, perhaps to lure intruders away. Young: Both parents feed the nestlings. Young leave the nest 1-2 weeks after hatching, usually around 9-10 days. 1-2 broods per year, sometimes 3.

Diet
Mostly insects and seeds. Feeds on many insects, especially in summer, including beetles, grasshoppers, caterpillars, moths, true bugs, and many others, also spiders and other invertebrates. Also eats many seeds, especially in winter, mainly those of weeds and grasses.
Nesting
Male defends nesting territory by singing from a prominent raised perch. Courtship may involve male running about on ground near female, with his wings and tail spread, sometimes fluttering into the air. Nest site is on the ground, often in a slight depression and placed at the base of a grass clump, weed, or shrub. Nest is a bulky open cup made of grass and weeds, lined with fine grass, rootlets, animal hair.

Songs and Calls

Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
