THE BIEDS OF COENWALL. 225 



1874-5, and again in 1895; rare at Scilly ; breeds in Jan Mayen 

 Island in Q-reenland ; in winter wanders as far south as the west 

 of France. 



Kittiwake ; resident, abundant round our coast and in our 

 creeks, esj)ecially in winter; some years ago bred in large 

 colonies on G-orregan, Scilly, but the numbers rapidly diminished 

 and recently the rocks there have been deserted ; still breeds at 

 MuUion Island, on Gull Eock. Falmouth, and occasionally at 

 least on the mainland ; on the continent not known to nest further 

 south than Brittany. 



Ivory Gull ; an accidental visitor from the coasts of Arctic 

 America, Labrador, and Newfoundland; has occurred about 

 thirty-five times in the British Isles and twice in the county, 

 namely at Quilquay and at Penzance in February, 1847 ; has a 

 completely circumpolar breeding range in high northern latitudes, 

 and in winter wanders down the European coast to France. 



Great Skua ; a casual visitor to our seas thi'oughout the year 

 except during the breeding months ; seldom seen on the coast, 

 and evidently much rarer now than twenty years ago ; breeds in 

 the Shetlands, the Faeroes, and Iceland ; in winter sometimes 

 seen on the north-west Atlantic coast of Africa. 



Pomatorhine Skua ; a casual autumn visitor of somewhat 

 uncertain appearance, but increasing both in numbers and 

 frequency; occasionally appears in large flocks as in 1879, when 

 it seems to have been abundant from Looe westward to Falmouth, 

 and in 1890 ; a specimen shot near the Manacles, June 15th, 1883 ; 

 nests in the north of eastern Siberia, in arctic America, and in 

 north Greenland ; in winter is found along the west coast of 

 Africa down to Wahisch Bay. 



Richardson's Skua ; a casual visitor in autumn and winter, 

 of rare occurrence on the south coast ; seen twice at Scilly ; nests 

 on the Shetlands and sparingly on the Orkneys and Hebrides ; 

 breeding haunts circumpolar, but not extending so far north as 

 several of the gulls ; in winter is found at the Cape. 



Buffon's Skua ; a casual visitor in autumn and winter, 

 represented by three specimens in the Cornish ornis up till the 

 autumn of 1891, when a large flock visited the south-west of 

 England, and the bird was seen in numbers near Polperro and
