Another 3 new Blackcaps this morning - will spring passage ever stop for this species or are these late birds failed breeders going walkabout ? Juv Coal Tit on site is a classic case of juvenile dispersal with most of our records of this species in the second half of June. Apart from this it's baby bird time of the year with a dose of young Dunnocks appearing today. Unfortunately we had uninvited visitors late yesterday evening with several acts of petty mindless vandalism in the observatory compound & on the nature reserve.
