0800-0845 A breakfast break at Oare produced a distant calling Cuckoo , which then circuited the W marsh calling and hotly pursued by a Magpie. Swallows were moving through in small numbers; a Reed Warbler was loud in the car-park reed-bed with  a Water Rail even louder, although unseen. Whimbrels were in the saltmarsh and a Common Tern was resting on a mooring buoy. A Nightingale was in full voice in the W side scrub—–seemingly mobile, unless there were two in the general area.
