1. Geese and Ducks: Geese and ducks, such as Canada geese and mallards, are known to graze on grass. Their diets primarily consist of various plant materials, including grasses, seeds, and aquatic plants.
2. Grasshopper Sparrows: Grasshopper sparrows are ground-dwelling birds found in grasslands. They feed primarily on insects but may also supplement their diet with grass seeds.
3. Savannah Sparrows: Savannah sparrows, also found in grasslands, consume a variety of plant material, including grass seeds, and occasionally blades of grass.
4. Mourning Doves: Mourning doves are ground-feeding birds that commonly eat seeds and grains. While their primary food source is not grass, they may consume grass seeds when available.
5. Bobolinks: Bobolinks are grassland birds that feed on seeds, insects, and occasionally grass blades. During the breeding season, they may consume grass blades to construct their nests.
6. Horned Larks: Horned larks are small ground-dwelling birds that primarily eat seeds. They may also occasionally consume grass blades.
7. Parakeets: Certain parakeet species, such as the budgerigar (commonly kept as pets), may eat grass as part of their diet. However, their primary food source should consist of a balanced seed mix and other appropriate foods.
It's important to note that birds have diverse diets that can vary depending on their specific species, habitat, and availability of food sources. While some birds do eat grass, it's not the sole component of their diet and is usually consumed alongside other food items like seeds, fruits, insects, and nectar.
