A very dull and dreary morning with little around early on but at least four House Martins and 20+ each of Swallow and Sand Martin later in the morning. I'd just done my full walk around the patch and was on my way out when some very vocal gulls drew my attention to an Osprey flying over the buildings to the west of the reservoir, apparently following the canal northwards. It turned to fly towards the reservoir and fortunately right over my head! By now though it had at least eight Lesser Black-backed Gulls, four Crows and about 15 Rooks on its tail so it didn't hang around at all and the last I saw of it it went back towards the canal and generally north up the Cherwell Valley.
A few other bits of note were at least one Siskin still around and two Willow Warblers.
Mike P was out in the evening and had an incredible sighting of six Little Ringed Plovers! Apparently this is the joint largest flock recorded in the B.O.S. area (excluding groups of adults with chicks) alongside the previous record in 1996.
