686 THE BIRDS OF YORKSHIRE. 



Larus glaucus. Glaucous Gull F. O. Morris reports one shot at 

 Rossington Warren some years ago ; R. Leyland says the Gulls and 

 Terns may be sometimes seen to alight about Halifax, but their visits 

 are so rare and so short as to be unworthy of notice ; A. Strickland 

 observes, " Mature specimens of this bird were, as far as I can ascertain, 

 quite unknown on this coast until the severe winter of 1830, when 

 considerable numbers were to be seen on the coast, and many were 

 procured ; I am not aware that they have been seen since, but the 

 young birds, called here the Cream-coloured Gull, are not infrequent 

 in winter, and a few are generally killed every year." 



This northern Gull, the " Burgomaster " of the Danes, is a 

 winter visitant to the Yorkshire seaboard, occurring not 

 infrequently in the immature plumage, from October to March, 

 at most of the coast stations between the Tees and the Humber ; 

 in some years it appears in considerable numbers, as in 1830, 

 according to Allis, and in 1875 (Tuck, Field, ist January 

 1876). 



Adult examples are rarer, though not uncommonly met 

 with a few miles out at sea, in severe winters. I have in- 

 formation of upwards of thirty occurrences, some of the data 

 being as follows : 



On the Yorkshire coast, several in 1830 and 1875. 



Kilnsea, Spurn, one on I3th November 1888. 



Bridlington, two in 1846-47, one in 1866, one in 1871. 



Flamborough, two in 1873, two in 1877, one in 1887. 



Filey, two in 1874, one in 1875. 



Scarborough, one in 1853, one on igth January 1867 ; 

 one, September 1887 ; some, autumn 1889. 



Whitby, one before 1880. 



Redcar, one on igth December 1878 (in Mr. E. B. Emerson's 

 collection) ; one on 8th January 1902 (in my collection) ; one 

 on 8th April 1903, seen on the beach in front of my house. 

 I have seen two other specimens at Redcar, but no particulars 

 respecting them are forthcoming. 



Being a true sea-bird it is of very rare occurrence away 

 from the coast ; one is said to have been taken at Rossington 

 Warren many years ago (fide Allis), and, so far as records show, 

 this seems to be the only instance of its appearance inland. 



This species is, like its compeers, of a ravenous nature,
