There can be few better ways of spending the beautiful, golden-lit evening of the longest day than out on the Brigg via the beach (both deserted and perfectly peaceful), and this family of Sand Martins served to raise our spirits further. Occupying a solitary nest hole in the strata almost at the tip of Carr Naze (very unusual for this highly gregarious and colonial species), they kept us entertained for a long while, allowing us to sit just a few metres away while they went about their business. Wonderful.
