360 APPENDIX. 



Iceland Gull Lams leucopterus, Faber. 



Winter visitant ; not uncommon on the east coast. 

 Kittiwake Eissa tridactyla (Linn.) 

 A visitant only to the east coast, generally in spring. 



Breeds abundantly in the west, at Handa, and on Bulgie Island ; also 

 on the north coast cliffs near Cape Wrath, but not so abundantly. 

 There are many roosting-places unoccupied by nests, such as one on 

 Bulgie Island, and another on the east side of Eilean Garbh. 



Family STERCORARIIN.E. 



Pomatorhine Skua Stercorarius pomatorhinus (Temm. ) 

 Rare visitant ; four were seen at Balnacoil on the 13th of October 1879, 

 a year famous for the number of these birds obtained all through the 

 country. 



Note. These birds appear to frequent the ocean and seas of the Outer 

 Hebrides in some numbers, every summer of late years. We saw them 

 not uncommonly west of Lewis in 1881. 



Richardson's Skua Stercorarius crepidatus (Banks.) 

 Autumn visitant ; breeding in one place in the county only, as far as is 

 known to us ; a pair, and one pair only, coming to the same spot year 

 after year. 



Stray examples have occurred in the west, but there are no known 

 breeding-sites. We have received the bird in the flesh from Handa, 

 but assuredly it does not breed there. 



Family PROCELLARIID^E. 



Leach's Petrel Procellaria leucorrhoa, Vieill. 

 A rare visitant. There is a specimen in the Dunrobin Museum that was 

 taken at Forsinard on January 10, 1877. 1 



Stormy Petrel Procellaria pelagica, Linn. 



Apparently a rare visitant. A specimen in the Dunrobin Museum was 

 taken at Scourie on the 30th of October 1845. 



We have never found this species breeding in Sutherland, but can 

 scarcely believe but that it is found on the Badcall Isles, and elsewhere, 

 nesting (see under Starling, antea, p. 343). They breed on the Pentland 

 Skerries, and occur in misty or hazy weather, not infrequently at the 

 lighthouse lanterns of Dunnet Head and Cape Wrath. 



ALC/E. 



Family ALCIM. 



Razorbill Alca torda, Linn. 



Occasional in winter and spring ; numbers thrown up dead after a storm 

 on the east coast, on these occasions far outnumbering the guillemots 

 in quantity, in about the proportion of six to one. 



1 As this species breeds on North Rona, it may occasionally be expected 

 to occur in Sutherland. (See Mr. J. Swinburne's Notes, Proc. Ryl. Phyl 

 Soc., 1883-4.)
