A bit of a shocker to end the month with seemingly very promising-looking mainly overcast conditions dropping no more than the most meagre sprinkle of new migrants. Wheatear and Willow Warbler got into double figures - in the case of the latter only just - on the ground at the Bill where Yellow Wagtails, Tree Pipits and Grey Wagtails featured in similar numbers overhead, but quality amounted to little more than 3 Pied Flycatchers scattered around the centre and south of the island. A Balearic Shearwater through off the Bill was the only seabird worth a mention.
A single Convolvulus Hawk-moth visited nicotiana flowers at the Obs at dawn and dusk, whilst the overnight immigrant tally from the moth-traps there consisted of 25 Rush Veneer, 18 Rusty-dot Pearl, 7 Diamond-back Moth, 3 Silver Y and a Dark Sword Grass.
