IVORY GULL. 

 Pagophila eburnea {Phipps). 



Accidental visitant from Arctic regions, of extremely rare occurrence. 



The Ivory Gull is an inhabitant of the far northern regions,, 

 and a rare accidental visitant to the Yorkshire coast. 



The first mention of it, as a county species, is contained 

 in Allis's Report on the Birds of Yorkshire, thus : — 



Larus eburneus. — Ivory Gull — A specimen was shot near Scarborough 

 many years ago, by the late Charles Watson of York ; he was no 

 ornithologist, but from the account he gave me of the bird, which 

 he said was pure white all over, there can, I think, be no doubt about 

 the species ; I believe the bird was not preserved. 



There are but seven instances of the occurrence of this bird 

 reported, the particulars of which are as follows : — 



At Scarborough, one shot " many years ago," by Mr. C. 

 Watson of York, is mentioned in Allis's Report. 



An adult male example is in the possession of Mr. T. M. 

 Edwards, who obtained it in Filey Bay, in August 1875 

 (Tuck, Zool. 1875, p. 4689 ; and 1876, p. 4960). 



A specimen in the second year's plumage was observed on 

 2nd November 1879, at East Scar, Redcar, while feeding on 

 a stranded fish. It was first fired at by a fisherman, who 

 missed it ; the bird then flew away, but returned to the feed,, 

 and was killed. It is now in the collection of Mr. E. B. Emerson 

 of Tollesby Hall {op, cit. 1881, p. 25).
