Meeting of Buzzards

In this field, were 9 possibly 10 Buzzard & 1 Red Kite all on the ground & spread quite evenly! Never seen such a spectacle. They didn't move really, as if gathered for a worm hunt. Gradually each bird left the field, some to trees on the fringe, others further. https://maps.app.goo.gl/GW6t6ZGF6Tb1fNNs5?g_st=am
