Great northern divers, or common loons as they are known in north America, are one of the largest species of diver. Like the other divers they are specialised and powerful underwater swimmers, catching fish with thick, dagger-like bills by sight. The chicks are able to dive only two days after hatching and will often sit on a parent's back for a ride around their territory. An adult can be host to 40 different body parasites.
