1. Saltgrass (Distichlis spicata): This grass is found in coastal salt marshes and is an important food source for snow geese during their winter migrations along the Gulf Coast of the United States.
2. Cordgrass (Spartina spp.): Cordgrass is a type of salt-tolerant grass that grows in marshy areas. Snow geese feed on the leaves and seeds of cordgrass during their migrations along the Atlantic coast and in their breeding grounds in the Arctic.
3. Bluejoint Grass (Calamagrostis canadensis): This grass is found in wet meadows and marshes, and it is one of the preferred food sources for snow geese during their breeding season in the Arctic and subarctic regions.
4. Reedgrass (Phragmites australis): Reedgrass grows in freshwater wetlands and is often consumed by snow geese during their migration and breeding seasons.
5. Wheat (Triticum spp.): Snow geese may occasionally feed on wheat and other cultivated grains when they come into contact with agricultural areas during their migrations.
Snow geese have long beaks that are well-adapted for grazing and pecking at vegetation. They often feed in flocks and may consume large amounts of grasses and other plants in a short period, especially during their migrations when they need to build up energy reserves for their long journeys.
