The Labrador duck (Camptorhynchus labradorius) is an extinct North American bird. The Labrador Duck has the dubious distinction of being the first endemic North American bird species to become extinct after the Columbian Exchange. It was already a rare duck before European settlers arrived and became extinct shortly after. As a result of its rarity, there is not an abundance of information on the Labrador Duck but there is some such as its habitat, characteristics, dietary habits, and reasons behind extinction. According to the Naturalis Museum there are 54 specimens of the Labrador Duck preserved in museum collections worldwide. However, according to Chilton, there are actually 55 specimens of the duck around the world.
