46 REPORT ON THE MIGRATION OF BIRDS. 



CorvusfrugileguSf Rook. — Spring, Newarp l.v., during March 

 and April, many flocks of Eooks and Crows are recorded as going 

 both to the west and east, as if a cross migration was going on to 

 and from the Continent. At the Cockle l.v., March 20th, 24th, 

 and 26th, continuous Eooks and Crows to icest. Llyn Wells, 

 April 30th, various flocks of Crows to south-icesty and at the same 

 station, on Aug. 8rd and 4th, large flocks to north north-east. 

 Autumn, with scarcely an exception, at all stations between the 

 Spurn and South Foreland, from the last week in September to 

 the end of the third week in November ; the rushes correspond 

 with those of the preceding. 



Alauda arvensis, Sky Lark. — As in previous years. Larks hare 

 crossed in immense numbers to the east coast ; it would be quite 

 unnecessary to give each occurrence in detail, almost involving 

 the necessity of writing a separate report. They are recorded 

 at all stations from the Farn Islands to Gull l.v., off the South 

 Foreland, from Sept. 1st to Jan. 3rd, 1884, and often con- 

 tinuously night and day ; rushes took place on Sept. 3rd, 4th, 

 and 21st, Oct. 6th and 8th, 10th to 14th, 27th to Nov. 2nd— 14th; 

 and Dec. 27th and 30th ; and again Jan. 3rd, 1884. Flocks 

 which come in at daybreak will continue to arrive till 12 or 

 1 p.m., when migration for the time ceases. Numbers are killed 

 during the night migration against the lanterns of the light- 

 houses and light-vessels.* Heligoland, Oct. 5th to Nov. 8th; 

 great rushes, Oct. 12th; 27th, night from 11 p.m., ''milliards
