134 Mr. W. Eagle Clarke — Bird-migration 



Gull was occasionally observed, but. only a single Herring- 

 Gull came under notice. Skuas, chiefly Richardson's and a 

 few Pomatorhines, were frequently in attendance on the Gulls. 

 1 saw one Tern, an immature example of the common species. 

 There were no Shearwaters, but I saw a single Fulmar. 

 Gannets, all adults, were not uncommon as passing visitors. 

 Common Scoters, Guillemots, and Razorbills were numerous 

 along the edges of the sands, and were chiefly in evidence 

 during the prevalence of strong westerly winds, when they 

 sought our side of the banks — the easterly — for shelter and 

 food. 1 also saw a few Red-throated Divers. 



One of the crew of the lightship who has been on board for 

 over a year and who, being a bird-fancier, knows all the small 

 cage-birds well, informed me that he had never seen a Gold- 

 finch, Linnet, or Redbreast on or about the vessel since he had 

 been stationed there. He had seen two Greenfinches, which 

 had arrived together during the spring. 



The object of the following list is to afford in a concise 

 manner some further information regarding each of the 

 species observed ; and also to give some idea of the various 

 movements performed by them. 



1. Turdus viscivokus. Mistle-Thrush. 



Observed in some numbers at the lantern and around the 

 ship on the early morning of Oct. 3rd, and again on the 

 night of the 17th and in the early hours of the 18th, 

 examples being captured on both occasions. One was flying 

 high to the W. at 11 a.m. on the 18th. 



2. Turdus musicus. Song-Thrush. 



Numbers, probably emigrants, were flying around the 

 ship between 2 and 4 a.m. on Sept. 18th and Oct. 3rd, some 

 being killed on the latter date. Many were again present 

 during the great night-movement of Oct. 17th-18th, when 

 several were killed at the lantern. 



3. Tukdus mekula. Blackbird. 



Was observed between 2 and 4 a.m. on Sept. 29th and
