Ammospiza is a genus of birds commonly known as saltmarsh sparrows. These small, migratory songbirds are primarily found in coastal marshes and wetlands across North America. They are known for their distinctive plumage, which often features streaks and muted colors that help them blend into their natural habitats. The genus includes several species, such as the Saltmarsh Sparrow and the Nelson's Sparrow. These birds primarily feed on seeds and insects, playing an important role in their ecosystems. Conservation efforts are crucial for their survival, as their habitats are threatened by development and climate change.
