The soapstone bird is the national bird of Zimbabwe and a national symbol. The flag of Zimbabwe was officially adopted on April 18, 1980. Prior to this flag, Zimbabwe was called Zimbabwe Rhodesia from June 1, 1979 until April 1980. Zimbabwe Rhodesia had its own flag, with horizontal stripes of red, white, and green from top to bottom, and a vertical black stripe along the hoist side. The bird statue was positioned at the top of the black stripe. When the country gained independence and changed to the name Zimbabwe, the current flag was adopted.
