Tringa semipalmata, commonly known as the Willet, is primarily native to the coastal regions of North and Central America. Its range extends along the Atlantic and Pacific coasts of the United States and Canada, and into parts of Central America, the Caribbean, and northern South America during migration.

Willets are typically found in coastal environments, including sandy beaches, mudflats, marshes, and estuaries. They are highly adaptive and can be found in both marine and freshwater habitats. During breeding season, they utilize inland wetlands and marshes.

Willets are shorebirds that feed primarily on invertebrates, such as insects, crustaceans, and mollusks, found in the mud and sand of their coastal habitats. They are well adapted to varying salinity levels and can exploit diverse wetland environments. Willets are also known for their loud calls and distinct wing patterns, which play roles in mating and territorial displays.
