Today's exercise walk also extended a little further than of late - to Kelvingrove Park and environs. Highlights were Kingfisher, Dipper, Grey Wagtail, Sand Martin and Goosander on the river, four singing Stock Doves in riverside trees and a nice patch of Valerian in flower. Bird of the day (and the week so far) has been Chaffinch (with Greenfinch a close second). Both species have been encountered all along yesterday's and today's route. This seems to be the peak singing period for the two species (I seem to remember that the males of these finches don't start singing in earnest until the nest is being built) whereas the tits seem to have all but stopped singing for the year. The Blue Tits in the box on the back wall of the house look set to fledge any day now.
