The prefix "Manx" in the name Manx Shearwater refers to the Isle of Man, a small island in the Irish Sea between Britain and Ireland. The species is known as the Manx Shearwater because the majority of the world's breeding population of this medium-sized seabird species is found on the Isle of Man. The name "shearwater" comes from the bird's unique flying technique of skimming over the water with its wings almost touching the surface.
