Savannah Sparrow

The Savannah Sparrow, Passerculus sandwichensis, is a small, New World sparrow and the sole representative of its genus. Exhibiting a widespread presence across North America, this bird is known for its adaptability to open grassland habitats. It is a sexually monomorphic species, meaning males and females are similar in appearance, and it displays considerable variability across its range with around 17 subspecies currently recognized.

Identification Tips

This species can be identified by its brown back with dark streaks and a white underside marked with brown or blackish streaking. It features a white crown and supercilium stripes, which may show hints of yellow, particularly near the beak. The cheeks are brown, and the throat is white. The flight feathers are blackish-brown with light brown or white borders, and the eyes are dark. The legs and feet are horn-colored, matching the lower part of the bill, while the upper bill is dark grey.

Habitat

The Savannah Sparrow favors open grasslands across its range, which includes a variety of environments from coastal areas to interior grasslands.

Distribution

This bird breeds from Alaska and Canada through the northern and central United States, extending into Mexico and Guatemala. Coastal Pacific and Mexican populations are generally resident, while others are migratory, wintering from the southern United States to northern South America. It is an occasional rare vagrant to western Europe.

Behaviour

Savannah Sparrows forage on the ground or in low bushes, often in pairs or family groups during the breeding season, and in flocks during migration. Their diet consists mainly of seeds, with insects also consumed during the breeding season. The flight call is a soft "seep," and their song is a mix of chirps and trills.
