THE ROOK {Corvns fruc/Uecjus), 



The first iinraigTaiion of Rooks was observed on the S.E. coast of 

 Suffolk on the 11th of September, when many arrived ; on the following 

 day vast numbers flying at a great elevation passed steadily inland. On 

 the 25th the first few migrants were seen on the south coast of Yorkshire. 

 During October from four to eight were seen passing south at the last- 

 named station on the 2nd, 6th, 18th and 19th, while on the 13th and 18th 

 small lots coming from the south-east arrived there from over the sea. 

 On the 19th, 20th, 30th and 31st strong immigrations were noticed on 

 the N.E. coast of Suffolk, the greatest numbers arriving on the 30th, 

 when they passed westward all day in thousands. On the 31st the 

 immigration was limited to a flock of 300 which appeared at a high 

 altitude at 12.30 p.m. and continued their course to the N.W. On those 

 two days the immigration was also noticed on the S.E. coast of Suffolk, 

 where the birds were arriving throughout both days, though the larger 

 numbers came on the 30th. Further arrivals of large numbers took place 

 ill that locality on the 9th and 21st of November, while on the N.W. coast 

 of Norfolk Rooks arrived from over the sea in a continuous stream on 

 the 5th of November from 6.50 to 8.15 a.m. 



An increase was noted in Staffordshire on the 20th of October. 



THE SKY-LARK {Alauda arvensis). 



The first migration recorded was of a few birds at Spurn Head Light 

 (Yorkshire) on the 22nd/23rd of August. On several days and nights 

 between the 8th and 14th of September a few recorded at the Owers 

 Light-vessel (Sussex) were probably emigrants. A large flock was noted 

 at Cromer Light (Norfolk) passing S.E. on the 11th; several were 

 noted on the 12th at Bardsey Light (Carnarvon) and were said to be 

 going north. 



The first indication of immigrants from the east was noted at the 

 Kentish Knock Light-vessel (45 miles E. by N. from the mouth of the 

 Thames), where moderate numbers were seen on the 17th/18th of 

 September, and on the following night some recorded from Hanois Light 

 (Guernsey) Avere possibly part of the same stream. A few were recorded 

 on the 22nd/23rd and 23rd/24th at Winterton Light (Norfolk) and on the 

 25th/26th and S6th/27th at Skerries Light (Anglesey) and Bardsey Light 

 respectively. On the 26th some were noted going west at the Vanie 

 Lio-ht-vessel (Kent) and on the 30th going S.S.W. at the N. Goodwin 

 Lio-ht-vessel (Kent). On the 17th and 22nd and from the 2oth to the 

 29th some were recorded at the Isle of May (Fife). From the 24th 

 until the end of the month migratory parties were noted passing to the 

 south on the south coast of Yorkshire, and on the 26th/27th a few were 

 killed at Spurn Head Light. On the 27th/28th many were recorded at 

 the Butt of Lewis Light (Outer Hebrides).
