ON THE AVIFAUNA OF THE OUTER HEBRIDES 17 



throughout the group during the past winter than was known before, 

 i.e. 1901-02. 



GLAUCOUS GULL (Lams glaucus), p. 148. Mr. Mackenzie of 

 Stornoway tells me that " a very good specimen of the Glaucous Gull 

 was shot by the keeper on the Gress shootings, and is now in his 

 (Mr. Mackenzie's) possession. It was got on the shore of Broadbay 

 three years ago ie., say, 1897 or 1898. 



Mr. W. L. MacGillivray shot one in mature plumage in March 

 1898, and another in immature dress in March 1900. A few 

 young birds are seen in the Barra seas every winter and spring, and 

 this is verified by Mr. M'Elfrish's notes for North Uist. 



POMATORHINE SKUA (Lestris pomatorhimis), p. 151. One is 

 recorded by MacGillivray as shot by him in Barra in October iSgs. 1 



BUFFON'S SKUA (Lestris parasiticus). There is one specimen of 

 the Long-tailed Skua in the possession of Dr. Mackenzie, North 

 Uist, which was caught alive at Scolpig, in that island, as I am 

 informed by Mr. W. L. MacGillivray. And Dr. M'Rury records 

 the first instance known to him of one on Barra on May 12, 1896 

 ("Ann. Scot. Nat. Hist." 1897, p. 150). 



GREAT SKUA (Lestris catarractes\ p. 151. Added to Birds of 

 Outer Hebrides. Buckley records one seen by him in M'Leay's in 

 Inverness on January 8, 1894, which had been shot at Abhuinnsuidh 

 (or Fin Castle) in North Harris. This is a first recorded occurrence 

 in the Outer Hebrides. The line of migration towards their 

 breeding grounds in Shetland and Faroe is probably further to the 

 westward and over sea, as, on the occasion of a visit to Rockall in 

 1896, some evidence of this was found. 



Another is recorded by Dr. M'Rury on the authority of Miss 

 Edgar, daughter of the lightkeeper at Barra Head, in the summer 

 of 1893. 



FORK-TAILED PETREL (P. lei(corrhoci), p. 154. Barrington tells 

 me (in lit. December 4, 1893) that the Fork-tailed Petrels on 

 Borrera, St. Kilda, nest in the "elects" or little turf houses of the 

 natives, among the sods of dry turf. 



Mr. Mackenzie told Mr. J. Young, on the occasion of the latter 

 gentleman's visit to Dunvegan, Skye, that hundreds (sic) of Fork- 

 tailed Petrels' eggs were sold every year at St. Kilda. 



1 In " Harting's Handbook" (ed. 2, p. 308) Buckley and I are quoted as 

 stating that this species " has been noticed in some numbers every summer in the 

 Hebrides" ("Fauna of Sutherland and Caithness," p. 235), but the correct 

 quotation is as follows : " These birds appear to frequent the ocean and seas of the 

 Outer Hebrides in some numbers every summer of late years." The line of their 

 migration towards the north appears to be further west than the shores of the 

 Outer Hebrides. The misquotation would almost make it appear that the species 

 was recorded by Buckley and myself as a bird nesting every summer in the Outer 

 Hebrides.
