Typically steady but a cracking day weatherwise. Best bird was a male Ring Ouzel near the ventilation shaft, which is my earliest ever here. I tend to pick them up from mid-month, assuming these are Scandinavian bound birds. C.100 Golden Plover were the first noted in a few weeks. Three Swallows and two Willow Warblers were my first of the year here (c.340m above sea level). Surprisingly no Wheatears here yet but a Nuthatch in trees by Doubting Farm.
