I went to see the Little Tern colony at Beacon Ponds, near Spurn Head on Monday, a very warm, sunny day. The Little Terns fished back and forth from the sea and the lagoon to the shingle beach where they nest, sometimes hovering for a while before diving head first. Some were sitting on nests. At one point, something spook them and they all took flight in a compact flock and circled around before settling again. A pencil and watercolour sketch.
