Freshwater fowl are aquatic birds that live in and around bodies of freshwater, such as lakes, rivers, and ponds. Two examples of freshwater fowl are teals and tealds. Teals are small, dabbling ducks that are found on every continent except Antarctica. They have a distinctive blue-green head and neck, and their wings are patterned with black and white. Tealds are a type of duck that is native to Europe and Asia. They are larger than teals and have a brownish-gray body with a white head and neck.
