Edit: I have just heard that our out-going Director of Conservation, Dr Mark Avery, had a Blackcap at The Lodge yesterday (24th) so....
A Wheatear on the grassland to the south of the reserve at lunchtime today was a delight to behold and brings up the 100. Not quite the calibre of LEO and other recent BTO ticks, but it now feels as if migration is finally under way.
BTO 99 - RSPB 100 (STA)
Also one of these, but they're common now. ;-)
