A cormorant. From Hungerford Bridge walking across from Waterloo to Charing Cross. Not just flying about but swimming, diving, and fishing, as only cormorants can do. We do give ourselves some stick in this country, sometimes justifiably so, but to see a sea-fishing bird feeding in an estuary of a river only 200 miles long that deals with the waste of 25 million people is, to me, something to be a little proud of.
