New World Sparrows
Savannah Sparrow
Passerculus sandwichensis
The Savannah Sparrow is a widespread and abundant New World sparrow, often found in open, grassy environments across North America. Though named for Savannah, Georgia, where it was first documented, it does not breed in that southern city. This species exhibits considerable variation across its range, with several recognized subspecies.

Bill
Has a small, conical, thick-based bill, with a dark gray upper mandible and horn-colored lower mandible.
02 / A place in the world
Where life
takes it.
Savannah Sparrows inhabit a diverse array of open environments, including grasslands, prairies, meadows, agricultural fields, and salt marshes. They can also be found in tundra during summer and along shores or in weedy vacant lots in winter. Habitat selection is influenced by the availability of low vegetation for nesting and open ground for foraging.
Stay a while. Or follow the season.
Most populations are migratory, breeding in Canada and the northern United States and wintering in the southern United States and Mexico. Some populations, particularly in coastal areas, are resident year-round. Migration primarily occurs at night.
03 / Listen a little closer
A voice
of its own.
The song begins with 2-3 chip notes followed by two buzzy trills, with the second trill often lower in pitch than the first. They also emit a thin, high-pitched "tsss" call.
04 / The life behind the feathers
A day in its world.
On the menu.
Their diet consists of a variety of insects, especially during summer, including beetles, grasshoppers, caterpillars, and spiders. They also consume many seeds, primarily from grasses and weeds, and some berries. Coastal populations may also eat tiny crustaceans and mollusks.
Savannah Sparrows primarily forage on the ground, walking or running to find food. They may also forage in shrubs and small trees. Young birds are fed mostly insects.
A place to begin.
The female builds an open-cup nest on the ground, typically hidden among grass or weeds, often under matted dead plants or overhanging grass, with a tunnel entrance. Clutches usually contain 2-6 eggs, which are whitish to pale tan or greenish with brown markings. The female incubates for 10-13 days, and both parents feed the nestlings.
The little routines.
These sparrows are not particularly shy and males often sing from exposed perches like fenceposts or shrubs during breeding season to defend territory and attract mates. When flushed, they typically fly up, flare their short tails, and land a short distance away.
One more reason to pay attention
A familiar face.
A few surprises.
The Savannah Sparrow was named by Alexander Wilson in 1811 for a specimen collected in Savannah, Georgia.
The "Ipswich Sparrow" is a pale, larger subspecies that breeds on Sable Island, Nova Scotia, and winters along the Atlantic coast.
A female Savannah Sparrow must gather approximately ten times her body weight in food to feed herself and her young during the eight days they are in the nest.
