Shearwaters earned their name by their ability to cut - or shear - the water with their wings, although until recently they were known as 'muttonbirds'. This name was given to them by early European settlers, who killed the birds for food and found that their flesh tasted like mutton.
There are many species of water birds; therefore it is important to look at the beak and feet to determine what they are and what they might eat. Birds having flat beaks such as swans and ducks eat mainly waterweeds, grass, seeds and a variety of beetles and bugs. Usually the chicks of these birds are self feeders and can be fed on grain, chicken pellets, and soft fleshy greens.
