A VISIT TO ST KIIDA. 175 



38. Woodcock Scolopax ru.sticola, Linnaeus. 

 "Ootacac." Probably passes on migration. 



39. Great Black-backed Gull Larus marirms, 

 Linnaeus. " Farspach." Common, and certainly 

 breeds in more or less abundance on Doon and 

 Soay. Much disliked by the natives because of 

 its egg-stealing propensities. 



40. Lesser Black-backed Gull Lani.s Jliscus, 

 LinniPus. Breeds in considerable numbers on the 

 various islands and stacks. 



41. Herring Gull Lams argentatus^ Gmelin. 

 Widely distributed over the islands, but nothing 

 near so common as the preceding species. 



42. Common Gull Larus crams, Linnaeus. Is 

 said to frequent the islands, but I did not observe 

 this species. 



43. Kittiwake Larus tridactijlus, Linnaeus. 

 "Ruideag." By far the commonest Gull in St. 

 Kilda, many of the cliffs being white with them. 

 Said to arrive in April and to leave in August. 



44. Great Skua Stercorarius catarrhactes (Lin- 

 nccus). An irregular visitor. 



45. Red-breasted Merganser Mergus serra/ur, 

 Linnaeus. " Sheiltach." A rare visitor, the coasts 

 being scarcely suited to its requirements. 



46. Eider Duck Somateria moH'issima (Linnaeus).
