Maybe the same bird as Brian Wyatt had near Steventon?
It put up plenty of birds, c200 Lapwing, many Gulls and Corvids and c50 Linnet.
Some local Cholsey news of a Chiffchaff calling along the Wallingford rd and a two Grey Wagtail with one in song at Winterbrook. Amazing what a bit of sunshine can do.
Thanks to Michael Pocock for the info.
