The Saint Helena plover (Charadrius sanctaehelenae) locally known as wirebird due to its thin legs, is a small wader endemic to the island of Saint Helena. Kittlitz's plover is the Saint Helena bird's closest relative. The Saint Helena plover is generally larger but not as well-marked as the Kittlitz's plover, which is native to sub-Saharan Africa.The bird was first mentioned in 1638, and is the national bird of Saint Helena, featured on the island's coat of arms and flag.
