Popped down for what turned out to be a very productive visit from around 0800 till around 1330. As well as 4 species of butterfly - Meadow Brown, Red Admiral, Peacock and Green Veined White, I managed to see 52 species of bird. Started well with a late Swift overhead, then a Jay passed over towards Invergowrie and kept going. There were a few Tree Pipits passing over (maybe 7 or 8 in total). A Kingfisher was on the burn. Spotted a Curlew Sandpiper among the Dunlins in flight. Had good views of 2 and a Ruff. Photos of the Dunlin flock shows that there were at least 5 Curlew Sandpipers. 1 Black Tailed Godwit and a Bar Tailed Godwit as well. Still a few Sandwich Terns lingering. Visits by 2 Ospreys (one which had an unsuccessful dive. Saw 2 Sparrowhawks (or maybe the same one twice) being mobbed by Swallows, and by a Carrion Crow. A small flock of Canada Geese dropped in. A few Stock Doves around. A Whitethroat, Grey Wagtail, Meadow Pipit, House Martin, Chiffchaff and Willow Warblers were nice to see as well. Heard but didn't see Blackcap, Great Spotted Woodpecker and a Greenshank.
