Barton-in-Fabis (opposite Attenborough across the Trent) In a patch of Dock fenced off by barbed wire were a flock of Yellow Wagtails. They restlessly fed, perching on Docks and wire fence where young Swallows waited to be fed by their parents. Suddenly a Juvenile Sparrowhawk shot out from the trees and chased a Yellow Wagtail, almost catching it, but was evaded and the hawk gave up followed by an irate flock of Swallows.
