Northern gannets form long term pairs and often return to the same nest again and again. They form large, dense nesting colonies (also known as gannetries) on steep rocky coastal cliffs. Northern gannets plunge dive at speeds of up to 60mph (100kph) into the sea, catching fish with their powerful bills. They feed on surface-schooling fish such as mackerel and herring. Their bodies are streamlined and well-suited for this diving behavior.
