Length: 12-14cm

By far the easiest Tern species to see, if not actually the most numerous - common terns breed at many locations inland, particularly at nature reserves where islands have been made specifically for them to nest. They can also often be seen over more or less any decent sized body of water with some luck. Visually very similar to the Arctic Tern, there are subtle differences, but you can almost guarantee that a tern of this sort seen inland is a common tern.
