Watercolour on paper, 210 × 297mm.
The Sandwich tern is a very white tern, with a black cap on its head, a long black bill with a yellow tip and short black legs. In flight it shows grey wedges on its wings tips and it has a short forked tail. In the UK, many of the important colonies survive because they are on nature reserves.
