THE BIRDS OF PAPA STOUR. 135 



brother's work on Shetland birds, has noted the enormous number 

 on the Ve Skerries ; but Mr. W. E. Clarke, who, with Mr. J. A. 

 Harvie-Brown, visited these rocks on June 11th, 1890, states 

 that only a few were seen. No eggs on any skerry. The birds 

 had probably not yet settled down for the season. 



Larus canns, Common Gull (Small Maw). A few pairs only 

 nest on the islets in the Sound of Papa. Mr. Clarke found a 

 single nest with one egg on the Ve Skerries. 



Larus argsntatus, Herring Gull (White Maw). Breeds com- 

 monly on the cliffs and stacks, but, contrary to the usual rule 

 throughout Shetland, is far outnumbered in this district by the 

 next species. 



Larus fuscus, Lesser Black-backed Gull (Saith-foul). Very 

 abundant, especially on Lyra and Fogla. 



Larus marinus, Great Black-backed Gull (Swabie, contr. for 

 Swartback). Almost every rock pillar has its pair of these 

 magnificent Gulls besides the large colony — unusual in Shetland 

 — on Lyra Skerry. 



Rissa tridactyla, Kittiwake (same) . Abundant on the cliffs of 

 Papa Stour. A few nest on Lyra Skerry, and I took a nest with 

 one egg before ascending the stack. 



Stercorarius crepidatus, Richardson's Skua (Allan). On June 

 7th, 1887, I saw a solitary individual sweeping over Papa Sound, 

 but this bird does not breed in the neighbourhood. 



A lea torda, Razorbill (Wilkie). Fairly abundant on Stour; 

 also breeds on Lyra and Fogla. 



Lomvia troile, Guillemot (Longie). Abundant on Stour ; and 

 also breeds on the Skerries, Lyra and Fogla. 



Uria grylle, Black Guillemot (Tystie). Nests all round the 

 island. I saw several fly out of their breeding-places, 100 feet 

 up the cliffs; also noted by W. E. C. off the Ve Skerries, where 

 it no doubt breeds. 



Fratercula arctica, Puffin (Norie). One solitary bird seen by 

 Mr. Eagle Clarke off the Ve Skerries, June 11th, 1890. 



Fidmarus glacialis, Fulmar Petrel (Mallie). One seen by Mr. 

 Scott, of Melby, and the men, circling round Lyra, while Peter 

 and I were engaged in the ascent. 



Procellaria pelagica, Storm Petrel (Swallow). Nests abun- 

 dantly in many places, but does not arrive at its breeding-haunts 

 until the last few days of June .
