Another lovely day in West Central Scotland. A short walk at lunchtime found four Swifts soaring high over the west end of Greenock, then careering between the tenements. Down at the esplanade, groups of Eider drakes were hanging about and a Great Black-backed Gull lumbered by. Back up near Ardgowan Square, a pair of Common Gulls were a complete surprise nesting on a ledge near the top of a three-storey tenement and mobbing a Carrion Crow which was scavenging rubbish on the pavement below.
