The song sparrow is a really uncommon vagrant to western Europe, with a number of recorded in Great Britain and Norway.

These birds forage on the bottom, in shrubs, or in very shallow water. They primarily eat bugs and seeds. Birds in salt marshes may eat small crustaceans. They nest both in a sheltered location on the bottom or in bushes or shrubs.

Song sparrows with areas of shrub cowl of their territory, away from the intertidal shoreline, have larger over-winter survival, in addition to increased reproductive success.

Color pattern

Song Sparrows are streaky and brown with thick streaks on a white chest and flanks. On a more in-depth look, the pinnacle is a horny mixture of heat red-brown and slaty grey, although these shades, in addition to the quantity of streaking, differ extensively throughout North America.
