Saint Helena
The flag of Saint Helena was adopted on October 4, 1984. It is a defaced (i.e. differentiated) Blue Ensign, i.e., a blue field with the Union Jack in the upper hoist-side quadrant and the shield from the coat of arms of Saint Helena centered on the outer half of the flag. The shield features a rocky coastline and three-masted sailing ship, with a Saint Helena plover, also known as a wirebird, atop. Prior to the adoption of the current coat of arms and flag in 1984, the flag and shield showed the ship and coastal scene taken from the colonial seal of the colony.
