VOL. vra.] NOTES ON MIGRATION. 227 



The direction of the wind affected the direction of 

 the flight to a remarkable extent. For several days 

 after my arrival there was a moderate north-east wind 

 blowing, and every day migrants came over the shingle 

 from the west or north-west, the majority flying parallel 

 to the coast and within one or two hmidred yards of 

 it mitil they reached the point. Then a few, even 

 when it was windy (chiefly Greenfinches), continued 

 across the sea, to east and to south-east, whilst many 

 Linnets and others flew round and round in the air, 

 finally departing from a fair altitude ; others rested 

 in the bushes, and quite a large proportion turned the 

 point and continued to fly parallel to the coast, north- 

 wards. In some cases these flocks, that had been flying 

 east, merged with flocks that had arrived from the 

 sea flying west, and the two flew north together ! 



Later, when the wind changed and for several days 

 blew from points between south and west, the majority 

 of departing birds came from the north along the coast 

 from Littlestone, and a smaller number from between 

 north and north-west, over the shingle. On windy 

 days some of these, similarly, turned the point and 

 continued their flight along the coast westward, so 

 that the flight of the previous few days was exactly 

 reversed, although the same species were involved. 

 Those that departed from the point, however, flew 

 nearly south-east, but more to the south of south-east 

 than to the east of it. 



Apart from the day movements it was evident that 

 some migration occurred at night. The numbers of the 

 various Thrushes seen among the bushes fluctuated 

 daily, and I frequently heard them at night. On 

 October 17th there were at least twenty-five Ring- 

 Ouzels, which seems to be a rather remarkable number 

 for that species. 



Small numbers of Great Tits, Eobins, Hedge-S'parrows, 

 Firecrests and Black Redstarts occurred, and larger 

 numbers of Wrens, Goldcrests and Stonechats. It was 

 not easy to tell where these birds came from : twice
