Terns
Order: Charadriiformes. Family: Sternidae
Terns are a group of generally general medium to large sea-birds typically with grey or white plumage, often with black markings on the head. Most terns hunt fish by diving but some pick insects off the surface of fresh water. Terns are generally long-lived birds, with several species now known to live in excess of 25 to 30 years.
