8o ANNALS OF SCOTTISH NATURAL HISTORY 



the gallery they came quite close up, and once or twice 

 were within an ace of striking the glass. Several Wheatears 

 and White Wagtails also appeared, on this, the only night 

 on which the weather conditions were favourable for the 

 display of the decoying powers of the lantern. 



On the two following days a number of Terns were 

 present off the south end of the island ; and on the night of 

 the 2oth, at 9 P.M., a party again appeared on migration 

 in the vicinity of the lighthouse, but as the night was clear 

 they did not approach the lantern, and only announced 

 their presence through their cries. 



The Common Tern has only recently been added to 

 native birds of Shetland. 



140. ICELAND GULL, Larus kucopterus. One was seen on loth 



December, and so well described that I have little hesitation 

 in accepting the record. This is another species about 

 which we have, as yet, little information relating to its 

 visits to Shetland. I have reason, however, to believe that 

 it is not very rare at Fair Isle during the winter months. 



141. POMATORHINE SKUA, Stercorarius poniatorhinus. An immature 



female was obtained on 2yth November. This, strange to 

 say, appears to be only the fourth known occurrence of 

 this bird for Shetland, and yet one would expect that it 

 must regularly visit the seas of the group on its passages 

 between its summer and winter haunts. 



142. RED-THROATED DIVER, Colymbus septentrionalis. One seen 



on loth September is the only example that has, as yet, 

 been observed at Fair Isle. It seems remarkable that this 

 species, which breeds in Shetland, as well as in Northern 

 Europe, should not have been noticed on any other 

 occasion. 



143. MANX SHEARWATER, Puffinus anglorum. A few were seen 



late in May, during June, and early in July. I should not 

 be surprised if the " Lingy Bird," as the Fair Islanders call 

 this species, bred in small numbers on the island. 



FULMAR PETREL, Fulmarus glacialis. We observed several 

 Fulmars hovering around and alighting on the cliffs at one 

 of their breeding stations on the and of September, but all 

 appear to have departed on the gth, for after that date we 

 saw them no more. It does not appear to leave its native 

 haunts for a protracted period, but like other species of 

 rock-breeding sea-fowl returns early in the year to its 

 nesting-places. Mr. George Stout informs me that in 1907 

 the first of these birds returned on iyth January and took 

 up their residence on the cliffs and stacks.
