While walking along the banks of the central London Thames, your attention is most likely to be focused on boats, bridges and buildings. Yet, if you if you pause for longer than a few moments when the foreshore is exposed during the rhythm of the tides, you will see some of the birds that that feed or breed along this stretch of the river. Having been largely limited to views from Victoria Tower Gardens, I have concentrated on its foreshore, where all the photographs below have been taken. Though they amount to just a few of the ninety-two species of birds that can be found along the tidal Thames and Estuary, they have been a delight to watch and an absorbing escape from the concerns and anxieties of life.
