last night at St. Catherine's Light also, while the largest emigrations 

 occurred on the 15th/16th and 16th/17th. 



During November and Decemher both the British and Continental races 

 were represented among the specimens taken at St. Catherine's Light. 



On the west coast numerous records were received from the light- 

 stations on the Isle .of Man, the Welsh Skerries, Bardsey Island and the 

 coasts of Pembroke and N. Devon. Very little evidence was, however, 

 forthcoming as to the direction the birds were taking ; in one or two 

 instances the flight was said to have been to the west or to the south, 

 but as the observations were all made at night too much reliance cannot 

 be placed on them. It is not improbable that both may be true and that 

 on this coast we have to deal with both emigratorj^ movements across 

 the Irish Sea and southward coasting movements. If the time of arrival 

 at the different stations is of any value, these perhaps point to a south- 

 ward movement on one or two occasions. 



From the 13th to the 16th of September there was a considerable 

 movement past the Welsh Skerries, and birds remained on the rocks for 

 two or three days, while others passed on the 24th/2oth. A movement 

 was also recorded on the 16th/16th off the Pembrokeshire coast, but with 

 these exceptions, no other migration was observed until mid-October. 

 On the 12/13th and 16th/17th of this month Thrushes were passing the 

 Isle of Man and on the 19tli the winter residents were recorded as having 

 arrived in the island. Great numbers passed the island again on the 

 21st/22nd, and small numbers were noted at Bardsey on the 25th/26th 

 and off" the Pembroke coast on the 27th/28th, while Lundy Island was 

 full of Song-Thrushes from the 28th to the 31st. The largest movement, 

 however, occurred from the 4th to the 14th of November ; the numbers 

 were very large and records were received from several lights on the 

 same night, pointing to a universal luovement over a considerable area. 

 It will be noted also that this movement corresponded almost exactly 

 with the main departure movement from the south coast. Similar 

 corresponding movements were noted from the Welsh and south coast 

 lights between the 9th and 16th of December, the greatest number being 

 noted at the Bardsey and Pembroke Lights on the 12th/] 3th. 



The great paucity of observations on this species by our inland 

 observers must be referred to ; it does not seem to be generally realised 

 that the Song-Thrush is a very active migrant. 



THE REDWING {Turdus iliams). 



The earliest records of an immigratory movement were received from 

 Fair Isle (Shetland) and the Isle of May (Fife) on September the 25th 

 and from the south coast of Yorkshire on the following day. On the 

 28th large numbers of Redwings arrived on the Isle of May, where they 

 only remained for a short period. No further arrivals were recorded 

 until the 10th of October, when enormous flocks were observed arriving
