The Savannah Sparrow, Passerculus sandwichensis, is a small sparrow.

This passerine bird breeds in Alaska, Canada, northern, central and Pacific coastal USA, Mexico and Guatemala. The Pacific and Mexican breeders are resident, but other populations are migratory, wintering from the southern United States to northern South America. It is a very rare vagrant to western Europe.

Savannah Sparrow is a very variable species, with numerous races, several of which have been split as separate species at various times. The different forms vary principally in the darkness of the plumage, with Alaskan and interior races the palest, and southern Pacific coastal forms the darkest.

This species has a typically sparrow-like dark-streaked brown back, and whitish underparts with brown or blackish breast and flank streaking. It has yellowish or whitish crown and eyebrow stripes. The cheeks are brown and the throat white.

The breeding habitat is a wide variety of open habitats including grasslands and cultivation. Savannah Sparrows nest on the ground, laying 3-6 eggs in a cup nest sheltered by a clump of grass or other vegetation.

These birds forage on the ground or in low bushes. They mainly eat seeds, but insects are also eaten in the breeding season. They form flocks on migration or in winter.

The song is mixture of chips and trills. The flight call is a thin seep.

This bird was named after Savannah, Georgia where one of the first specimens of this bird was collected.

Although this bird is generally abundant across its range, some coastal populations depending on salt marsh habitat are declining.
