186 BIRDS OF THE HUMBER DISTRICT. 



241. URIA GRYLLE (Linnaeus). Black Guillemot. 



Provincial. Greenland Dove. 



This pretty species is occasionally found in the 

 neighbourhood of Flamborough and along the coast 

 in the autumn, winter, and spring. I have met with 

 it off our shores, in the mottled plumage, as late as 

 the end of May. 



Mr. Boulton had three immature specimens within 

 the last four years from the vicinity of Flamborough, 

 and thinks it is becoming rare along the east coast. 



The Black Guillemot is a late breeder, going to 

 nest a month later than the common species. 



242. ALCA ALLE, Linnaeus. The Little Auk. 



This little Arctic bird is a winter visitant to the 

 coasts of Yorkshire and Lincolnshire, and in severe 

 weather is sometimes seen within the Humber. There 

 are numerous instances of the Little Auk occurring 

 far inland, driven in by stress of weather. 



Mr. Boulton had two in the flesh, shot on the river 

 Hull in the autumn of 1861 one late in October, 



in five hundred ; on the Isle of Handa, on the west of Suther- 

 landshire, on the authority of Mr. Harvie Brown, as one in one 

 hundred ; on Barra Head and the Stack of Lianamull, accord- 

 ing to a most careful scrutiny by Mr. Harvie Brown and 

 Captain Fielden, one in five (Gray's < Birds of the West of 

 Scotland/ p. 426). 



The late Mr. Oassin (Birds of North America, p. 914) says 

 "it is one of the mogt common birds of the higher northern 

 latitudes on both sides of the continent."
