Vesper Sparrow

Pooecetes gramineus

A rather chunky sparrow of the open fields, known at all seasons by its streaked appearance and its white outer tail feathers. In summer, its clear musical song may be heard at any time of day; but the naturalist John Burroughs, feeling that it sang most impressively in the evening, gave it the name of Vesper Sparrow. Not as shy as many grassland sparrows, it can be observed rather easily. It is often found dust-bathing in bare soil of fields or dirt roads.

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.

How climate change could affect this bird's range

In the broadest and most detailed study of its kind, Audubon scientists have used hundreds of thousands of citizen-science observations and sophisticated climate models to predict how birds in the U.S. and Canada will react to climate change.
