THE BIRDS OF THE ISLAND OF BARRA 209 



BLACK-HEADED GULL, Larus ridibundus, L. Not uncommon during 

 greater part of year, but I am not sure if any breed on the 

 island : certainly not large colonies. 



COMMON GULL, Larus canus, L. Abundant at all times, and 



breeding. 

 HERRING GULL, Larus argentatus, J. F. Gmelin. Plentiful all the 



year, and breeding. 

 LESSER BLACK-BACKED GULL, Larus fuscus, L. Common all the 



year, but not very abundant. 



GREAT BLACK-BACKED GULL, Lams marinus, L. Common at all 

 times. On an island near Mingalay I counted at least twenty 

 pairs breeding last season. 



GLAUCOUS GULL, Larus glaiicus, O. Fabricius. Occasionally seen 

 during severe winters. I have met with three or four of them. 



ICELAND GULL, Larus leucopferns, Faber. One young bird, which I 

 examined, was got here in the winter of 1893. 



KITTIWAKE GULL, Rissa tridactyla (L.) Large colonies breed in 

 the rocks of Mingalay and Bernera, and a few birds remain 

 round the coast all the year. 



GREAT SKUA, Stercorarius catarrhactes (L.) A Great Skua was 

 identified early last summer (1893) at Barrahead by Miss 

 Edgar, daughter of the principal light-keeper. It flew quite 

 close to the lighthouse, but seemed to be only passing, as she 

 did not see it again. 



POMATORHINE SKUA, Stercorarius pomatorhinus, Temminck. Seen 

 occasionally round the coast in summer and autumn. 



RICHARDSON'S SKUA, Stercorarius crepidatus, J. F. Gmelin.- Regular 

 summer and autumn visitors, but I do not think they breed 

 here. 



MANX SHEAR-WATER, Puffinus anglorum, Tern. Occurs round the 

 coast, and a few are said to breed in one of the southern 

 islands ; but they have deserted their old breeding-places at 

 Mingalay some years ago, and the Common Fulmar is seldom or 

 never seen about the coasts. 



FORK-TAILED PETREL, Oceanodroma leitcorrhoa, Vieillot. Occurs 

 round the coast, and a few may be breeding in the southern 

 islands. 



STORM PETREL, Procellaria pelagica (L.) A few are seen about the 

 coast ; but it is doubtful if it breeds anywhere on the islands 

 of Barra at present, although at one time it seems considerable 

 numbers of them bred in Mingalay Island. 



RAZORBILL, Ale a torda, L. --Very abundant at the southern 

 islands during the breeding season, and a few birds remain on 

 1 2 C
