Walked around Balgray Reservoir this afternoon. Conditions not ideal for birdwatching with quite a blustery wind. However good numbers of Willow Warblers, Sedge Warblers and Whitethroats were in song and a pair of Great crested Grebes were displying. Plenty of Swallows about but no Swifts. A sandpiper species was alarm calling on the shore. The call didn't sound exactly like Common, and when the (until-then-invisible) bird was flushed, it flew up at an angle of 30-45 degrees, banking and arcing away quite high up (completely unlike the typical skimming flight of Common). In terms of colour, the overall impression was of brown and white. Oh well - another one that got away.
This evening, a Grey Heron was fishing under the iron bridge at Glasgow Botanic Gardens while a female Mallard shepherded about 4 or 5 tiny young into cover.
