November flocks, often associated with Hooded Crows and Jackdaws, 

 were seen arriving on the Suffolk coast from the E. or N.E. or were ob- 

 served inland passing over to the west. These arrivals produced an 

 increase of Rooks generally which became apparent about the middle of 

 October and which was also recorded from Lincolnshire. Inland in 

 Kent a flock was seen on passage going N.W., and at Bo*ham (Sussex) a 

 very large flock was seen to arrive from the N.E. on the 4th of October 

 and pass on to the W. On the 15th, 16th, 18th' and 30th flocks were 

 seen coasting to the south at Lowestoft (Suffolk). What has been said 

 under the Hooded Crow with regard to the east-coast light-stations 

 applies equally well to the Rook, as the two species are frequently in 

 company and are not as a rule differentiated by the light-keepers. 



In Scotland during the second half of October small arrivals were noted 

 at the Northern Islands, and a flock of thirty was seen at Fair Isle (Shet- 

 land) on the 30th. On the 4th of November three visited the Flannan 

 Isles (Outer Hebrides). On the 8th a few were again noted on Fair 

 Lie, where stragglers occurred until the end of the year. 



THE SKY-LARK {Alauda arvensis). 



Autumn migration commenced with the arrivals of small numbers in 

 Northumberland on the 6th and 9th of September, on Holy Island 

 (Northumberland) on the 12th and at Spurn Head (Yorkshire) and the 

 Suffolk coast on the 13th. Another small arrival was noted at Holy 

 Island on the morning of the 14th, but passed on at once. This was 

 followed by the advent of larger numbers on the 16th, and by a 

 further increase on the Suffolk coast on the following day. Quite 

 small parties moving in Kent were noted during September. On the 

 Sussex coast, where it was noted the local birds left soon after breeding, 

 the first arrivals coming from the N.E. appeared on the 23rd followed 

 by further numbers on the 29th and 30th. Except for single birds at 

 Ilanois Light (Channel Islands) on 12th/13th and at St. Catherine's 

 Light (Hampshire) on 14th/15th, there were few records from the light- 

 stations in September; immigrants were noted, however, at the Kentish 

 Knock Light-vessel (Essex) on the 14th and at the Shipwash Light- 

 vessel (Suffolk) and Outer Dowsing Light-vessel (Lincolnshire) on the 

 28th and 29th ; some were seen coming in from the east at Yarmouth 

 on the 27th and an increase was noted the following day on the Suffolk 

 coast. A few were killed at the Skerries Light (Anglesey) on 17th/18th 

 and at the South Stack Light (Anglesey) on the following night. 



In Scotland large arrivals from the Continent took place after mid- 

 September and were noticed at the Orkney and Shetland light-stations 

 more especially ; at Auskerry (Orkney) a flock passed the island going 

 S.W. on the 28th. Similar movements came under notice at other
