- The Field Sparrow often feeds directly on fallen seeds. It may fly to the top of grass stalks, let its weight carry the stems to the ground, and then begin removing the seed.
- If a male Field Sparrow survives the winter, it usually returns to breed in the same territory each year. The female is less likely to return to the same territory, and young sparrows only rarely return the next year to where they were born.
- The male Field Sparrow starts singing as soon as he gets back in the spring. He sings vigorously until he finds a mate, but after that he sings only occasionally.
- Breeds in old fields, woodland openings, and edges.
- Winters in fields and forest edges.
