data, to indicate the times of the first appearance of the 

 various migrants, and the dates of the occurrence of the more 

 interesting species. 



August. Throughout the month the volume of migration was 

 considerably in excess of that of preceding seasons, and was 

 probably due to continental climatic influences. On the ist of 

 the month a Green Sandpiper appeared ; on the 3rd, several 

 Turnstones; on the 5th, no less than 20 Green Sandpipers were 

 seen, also 6 Greenshanks, many Common Sandpipers, and an 

 Icterine Warbler, the last being a month earlier than any previous 

 record for this bird's appearance in autumn in the British Isles. 

 On the 7th, a Garden Warbler (earliest record for passage known 

 to us), also Knots and more Green Sandpipers, Greenshanks, and 

 Common Sandpipers; on the 8th, Temminck's Stint and Willow- 

 warbler (early) ; on the 9th, White Wagtails (earliest date for 

 passage) and several Willow-warblers; on the 10th, an Icterine 

 Warbler and a number of Sanderlings; on the 13th, a Purple 

 Sandpiper; on the 19th, several Whinchats (earliest record), and 

 a Long-eared Owl (also earliest) ; on the 20th, a Wood Sandpiper ; 

 on the 2 1 st, 2 Curlew Sandpipers (new to the avifauna of the 

 island), and two more Icterine Warblers; on the 22nd, 2 Wrynecks 

 (early), a Barred Warbler, and an early migrant Kestrel ; on the 

 24th, a Red-backed Shrike, a Lesser Whitethroat, and a Pintail ; 

 on the 29th, Common Whitethroats (early); and on the 30th, a 

 Pied Flycatcher. 



There were few White Wagtails after August, which is a departure 

 from what has happened in other seasons, when September has been 

 the main month for their passage. 



September. Until the 20th, when the wind passed from north 

 and west to south and east, little migration was observed. On the 

 2nd, the first Redstarts appeared, and were followed by Snow- 

 buntings and Wigeon on the 7th. On the 14th, Greater Wheatears 

 and Lapland Buntings were seen; on the 19th, the Jack Snipe; 

 on the 20th, a Scarlet Grosbeak and a Barred Warbler; on the 

 21st, a Great Snipe, Redwings, Blackcaps, and Brent Goose; on 

 the 22nd, a Turtle Dove; on the 24th, Blyth's Reed-warbler, 

 Siskins, Slavonian Grebe, Greater Wheatears (many), Bramblings, 

 and Hedge Accentors; on the 26th, Chaffinches, Grey-headed 

 Wagtail, Fieldfares (2), and Song -thrushes; on the 27th, a 

 Spotted Flycatcher; on the 28th, Tree-pipits, Ring-ouzels, Gold- 

 crests, Redbreasts, Ring Doves, Little Bunting, Black Chat, and
