The House Martins are back in their nests in the cornice of the Kuwaiti Embassy in Knightsbridge, just outside the park. Their nests on top of the petals of the downward-facing plaster flowers are quite unlike normal ones, and are invisible from the ground. I shot this video from under the porch of the French Embassy opposite the Kuwaiti one, and the sound track includes me explaining to a suspicious French official what I was doing. The French used to have nests on their embassy too until they installed anti-bird defences, and all the House Martins decamped to the building opposite.
