The local Lesser Black-backed and Herring Gulls were making a tremendous racket over the Bonnyholm estate this evening. Eventually the cause of the commotion was revealed when a Grey Heron came lumbering into view from among the houses. Presumably it had been after Starling fledglings or maybe someone's Koi Carp. Two Kingfishers were adding to the noise along the river. The singing Willow Warbler which had been present for a few weeks has either stopped singing or moved on as I haven't heard him in over a week. There are still plenty of Blackcaps in song (four tonight) with at least two Chiffchaffs as well.
