As the first of September rolled around, it was with clear skies and not a breath of wind. Another excitingly species-rich day, if a little disappointing on the numbers side as the open blue skies proved to be too enticing to migrants who may have otherwise taken brief respite in the garden. Despite the pitiful ringing tally, birds were clearly on the move with fly-over waders including 
Wood Sandpiper, 
Ringed Plover, 
Curlew and 
Whimbrel, as well as a lone 
Sanderling settled beside
 Pulpit rock. On the ground the first 
Firecrest of the autumn was in the Obs garden accompanied by single figures of 
Spotted Flycatcher, 
Pied Flycatcher, 
Willow Warbler, 
Reed Warbler and 
Blackcap. The warm, clear afternoon saw an influx of insectivores with a mixed hirundine flock over the Bill Common of 
Swallows, 
Sand and 
House Martins being joined by 14 
Swifts. Elsewhere on the island, Reap Lane harboured a single 
Pied Flycatcher and two 
Whinchats,
 whilst Bowers Quarry saw those totals and raised them a 
Lesser Whitethroat; a 
Short-eared Owl was also at Barleycrates Lane. Four 
Balearic Shearwaters and 2 
Arctic Skuas passed through on the sea at the Bill.
The Wood Sandpiper was sufficiently high in the clear, blue sky that although clearly audible to several birders in different spots around the Bill nobody actually managed to clap eyes on it; several calls were also picked up by the nocmig recorders at the Obs that had been left running well after dawn:
And by way of comparison, here's a Green Sandpiper recorded over the Obs a few nights ago:
