A saltwater sparrow needs a marsh with plenty of bugs and snails to eat, as well as native grasses suitable for building her nest. When road construction damages marshland and the invasive grasses take over, the sparrow flies along the Atlantic coastline. She finds a marsh where people are removing invasive grasses and planting native ones. A human catches her, measures her, and tags her leg. Released, she settles in a nearby nesting spot that offers her protective cover, nest-building materials, and plenty of bugs. Illustrated with attractive digital artwork including a range map, the story of the bird's plight is engaging. From the Animal Habitats at Risk series (6 titles), this informational picture book uses narrative to communicate the vital importance of protecting and restoring native animals, plants, and ecosystems.
