Best birds of today's walk between Kirkintilloch and Lennoxtown were two Chiffchaffs, my first singing birds of the year. Also notable were four occupied rookeries (84 nests in total) near the centre of Milton of Campsie, a warbling Redwing and Dippers at three sites. Later in the day, more Rooks (31 occupied nests) were nesting in Fountain Gardens in Paisley where another Redwing was warbling (as they tend to do at this time of year).
