*Birds tagged by restoration projects are distinguished by the color, code and type of marker they are wearing. The MN DNR, Hennepin Parks and Michigan DNR use orange and green wing tags. Hennepin Parks, Wisconsin DNR, Iowa DNR and Lacreek National Wildlife Refuge in South Dakota use yellow, green and red collars.
