With the pink and white roses and the honeysuckle bines scrambling through the trees, a delicious ambrosia of fragrance lingered heavily on the air. On the sand bank in the centre of the estuary the curlews gave their liquid burbling call of pure happiness, and where a heron tall and grey was wading through the shallows. However, he soon became aware of our presence and with the slow and stately beat of his wings, and his longshanks trailing behind, as he takes to the air, a slow and tranquil mood was evoked.
