Spent the day in Edinburgh. While watching the "Riding" down the Royal Mile before the opening of the Scottish Parliament, noticed a patch of Biting Stonecrop (see photo below) on top of an old wall. Earlier, counted 100 Grelag Geese beside St Margaret's Loch (and numerous Mute Swans on the loch itself). Later, saw 11 greylags, 8 Canada Geese, 2 Mute Swans and 2 Herons on Dunsapie Loch (plus 4 more swans overhead). Still plenty of interesting plants about. Noticed Wild Thyme (past flowering), a few Harebells, Yarrow and the pink-flowered herb shown below on Salisbury Crags, and Hart's Tongue Fern, Wall Rue, Herb Robert and the Bugloss species shown below beside the road south of Arthur's Seat. Also, the marshes next to Duddingston Loch were covered with a blue haze when viewed from above (probably Devil's Bit Scabious), and in gardens in Ulster Crescent were Welsh Poppy, Borage and Autumn Crocus, all in flower.
