A day after I saw a Great White egret on the pools there were four little egrets in exactly the same spot. Little egrets arrived in Britain from the south in the second half of the 20th century and didn't actually breed here until 1996 but they are now a common site along the coast. Much smaller than the Great whites and a key feature are the yellow feet you see as they pick their way in shallow water. We have already seen them on Shingle Marshes when it was first flush with water, and they will return when it fills up again.
