Bachman's Sparrow
Peucaea aestivalis
| Conservation status | Around beginning of 20th century, range of species expanded well to the north, as the bird moved into brushy areas and second-growth created by cutting of forests. The range has since contracted sharply again. Bird is now uncommon and possibly declining in the South. Loss of habitat is a major current problem. |
|---|---|
| Family | New World Sparrows |
| Habitat | Open pine or oak woods, palmetto scrub, bushy pastures. Favors relatively open grassy areas. Historically was most common in understory of mature pine forest, where frequent fires limited the amount of brush; as mature forest has become scarce, more Bachman's Sparrows are found in clearcuts, powerline rights-of-way, old pastures, and other open areas. |

Feeding Behavior
Forages almost entirely on the ground, moving rather slowly in a limited area. Picks up items from ground or jumps up to take items from low vegetation.
Eggs
3-4, sometimes 2-5. White, unmarked. Incubation is by female only, about 12-14 days. Young: Both parents bring food to the nestlings. Young leave the nest about 9-10 days after hatching. 1-2 broods per year, perhaps rarely 3.

Diet
Mostly seeds and insects. Diet is not known in detail. In summer, majority of diet apparently is insects, especially beetles, caterpillars, grasshoppers, also other insects and spiders. Also eats many seeds, particularly those of grasses; seeds may be especially important in diet in winter.
Nesting
In southern areas, members of a pair may remain together at all seasons. Beginning in early spring, male sings to defend nesting territory. Nest site is almost always on the ground, typically placed at the base of a shrub, clump of grass, or palmetto. Occasionally placed a few inches above the ground, within the base of a weed or grass clump. Nest (built by female) is an open cup made of grass, weeds, rootlets, lined with fine grass and animal hair. Often has a domed top of woven grasses at least partially covering nest.
How Climate Change Will Reshape the Range of the Bachman's Sparrow
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.
