From John Archer-Thopmson:
Watching about 50 jackdaws on the cliffs just south of the Deer Park yesterday (20th September), impressive as it was, they were then joined by another group of about the same size. At one point they were all flying about. Really spectacular to see a cloud of c.100 jackdaws, I don’t think there were any other Covid’s involved. There were also at least 10 choughs on the deer park including young of the year.
