Spent a sunny day down in Inverclyde. First bird seen was an Osprey circling over the Clyde near Newark Castle. There were two broods of Tufted Ducks on Town Dam - one of two medium-sized chicks and one of four tiny ones. An unusual Mallard was also present. It had quite exaggerated colours and a lot of white patches. Down at Gourock, two Black Guillemots were in the bay, three Swifts were overhead and a Sandwich Tern flew past, pursued by two juveniles.
