                         Distribution - The Northern Pintail duck occurs 
                        throughout all of North America, breeding north of their 
                        local range and wintering south, sometimes as far as Central 
                        America and the West Indies. They prefer marshes, prairie 
                        ponds and tundra and may sometimes winter in salt marshes. 
                        
                      
  
                        Biology - Awidespread and common duck, the Northern 
                        Pintail duck flocks in large groups of up to a thousand. 
                        Males are often aggressive, forcing their attention on 
                        females of other species. It is a grazer.
