Editing Song sparrow (section)

==Distribution and life history==
Though a habitat generalist, the song sparrow favors brushland and marshes, including salt marshes across most of [[Canada]] and the United States. They also thrive in human dominated areas such as in suburbs, agricultural fields, and along roadsides. Permanent residents of the southern half of their range, northern populations of the song sparrow [[bird migration|migrate]] to the southern United States or [[Mexico]] during winter and intermingle with the native, non-migratory population. The song sparrow is a very rare vagrant to western [[Europe]], with a few recorded in [[Great Britain]] and [[Norway]].

These birds forage on the ground, in shrubs or in very shallow water. They eat mainly insects and seeds. Birds in salt marshes may also eat small [[crustaceans]]. They nest either in a sheltered location on the ground or in trees or shrubs. Song sparrows with areas of shrub cover in their territory, away from the intertidal coastline, have greater over-winter survival, as well as higher reproductive success.<ref name="adultsurvival"/>
