A Cuckoo (my first of the year) was singing on Stockie Muir as I passed on my way over to Loch Lomond first thing. In spite of the cold, plenty of birds were active. Final totals for a three hour walk from Rowardennan to Rowchoish were five Wood Warblers, forty Willow Warblers, 13 Blackcaps, two Chiffchaffs, four Redstarts, two Pied Flycatchers, four Tree Pipits, four Nuthatches and a single Cuckoo. Four Common Sandpipers (including a courting pair) were along the shoreline and best of all (after a lone single last week) were four Red-breasted Mergansers.
