An early morning spent marking (Grr!!) was brightened up a bit by having the Abernethy webcam on in the background. Chaffinches were singing when I tuned in but later participants included a Buzzard mewing at 08:00 and Great Spotted Woodpecker peeping and drumming at 09:10.
An afternoon walk from Baron's Haugh to Hamilton produced a pair of Shoveler, three Gadwall and six Sand Martins on the haugh, two singing Willow Warblers and five Chiffchaffs along the Clyde, three Grey Wagtails, a Dipper and more Sand Martins on the Avon under the M74 flyover and a pair of Ravens at a possible nest site in the general area. Flowering Butterbur and the constant singing of Blackbird, Robin, Wren, Chaffinch, Goldfinch, Dunnock etc added to a lovely afternoon.
This evening (back at the marking - Grr!! Grr!!), about 20:45, a flock of Pink-footed Geese were heading north, high over the house in South Cardonald, giving their "Wink,wink-wink" call.
