First birds of today's Big Clyde Bird Day were Black Grouse and Cuckoo on a moor north of Glasgow. A long walk up the west side of Loch Lomond produced many common woodland birds (Willow Warbler, Chiffchaff, Blackcap, Gardn Warbler, Chaffinch, Lesser Redpoll, Blackbird, Song Thrush, Robin and Wren) but none of the Oak woodland specialists (Redstart, Tree Pipit, Wood Warbler, Pied Flycatcher) found on the east side. The shores of the loch held Common Sandpiper, Greylag and Canada Goose, Red-breasted Merganser, Goosander, Mallard, Grey Wagtail and Osprey. One of the lagoons held an Otter.The main target bird, Mandarin, was not located. However a trip to Jamestown found six males (including one in eclipse) lurking in their regular slot. Lang Craigs held calling Green Woodpecker and Cuckoo.
