 on the 4th. The autumn movement of Whinchats began at 

 Largo on the loth and at Kirkliston on the I3th, on which 

 day Meadow-pipits also began to pass there. A female 

 Crossbill of the curvirostra curvirostra type was found starved 

 on St. Kilda on the /th (1.1910.246), and a Crossbill arrived 

 on the Bass on the loth and stayed a week. In many

 Isle of May. After the middle of the month Lapwings 

 are recorded in some numbers from Fair Isle and North 

 Ronaldshay, and by the 2Oth Wheatears were passing at 

 the Flannans and Redstarts in East Fife. On this date an 

 assembly of " hundreds if not thousands " of Swifts was 

 seen near Corstorphine, and on the last two days of the 

 month many were present at the Butt of Lewis. Small 

 numbers of Herons were seen at Fair Isle and Barra Head. 

 Bar-tailed Godwits are recorded from the Cromarty Firth 

 on the 23rd, Largo Bay on the 24th, and Aberlady Bay

August. The type of pressure distribution in August 

 was of a very unstable character. The direction of the 

 wind in Scotland varied greatly, while in Shetland there 

 was a large proportion of breezes from the NE. Constant 

 migration southwards is recorded, but only small numbers 

 of birds at a time. Wheatears, Whinchats, and Cuckoos 

 are recorded from many places as passing on migration, 

 while during August the majority of Swifts left Scotland. 

 Common Sandpipers, Green Sandpipers, and Greenshanks 

 were also on the move. On the ist, Sanderling returned to 

 Largo Bay, Knots to Aberlady, and a Storm-petrel was 

 found dead at North Berwick. Seven Crossbills were noted 

 at Barra on the 3rd (1.1910.246), while by the yth Willow- 

 warblers were on return migration at Fair Isle. On the 

 8th three Sedge-warblers and a Willow-warbler struck the 

 lantern at the Mull of Galloway, while nine Crossbills 

 arrived on Fair Isle (1.1910.245) ; two which were procured 

 proved to be Loxia curvirostra curvirostra. An immature 

 Crossbill was procured at Torphins (Deeside) on the 9th
