GLAUCOUS GULL 439 
district it has occurred only in winter, and not in quite 
mature plumage (H. A. Macpherson). Immature birds are 
seen on Barra, in the Outer Hebrides, every winter and 
spring (Harvie-Brown). 
Specimens have often been procured along the eastern 
sea-board of England, the bird becoming scarcer along the 
southern coast. In some seasons this Gull occurs in far 
greater numbers than at other times. Thus in January, 
1881, several were brought ashore in_ fishing-smacks, 
twenty-seven being offered for sale in one lot at Great 
Yarmouth (A. Patterson, ‘ Zoologist,’ 1901, p. 296). On the 
western side of England and in Wales it is quite uncommon. 
From Ireland there are numerous records, especially 
from the north-western sea-board. The bird probably 
occurs in other districts more often than is supposed, 
but in the absence of observers has no doubt been over- 
looked. I am strongly inclined to think that it appears 
annually along the Irish coast, though in some seasons 
few only may occur. According to Sinclair, Rathlin Island 
and the coast of Donegal are visited every winter. From 
the Mayo coast, Mr. Warren cites many instances (‘ Irish 
Naturalist,’ 1892, p. 154), and the coasts of Galway, Kerry, 
and Cork, have also been visited. The Glaucous Gull is 
apparently rarer on the eastern shores of Ireland: how- 
ever, I have noted several on the slob-lands of Dublin Bay. 
On the coasts of Wicklow and Wexford it has not been 
identified (Ussher). An unusually large visitation of this 
and the next species took place in the winter of 1892, when 
birds were obtained in districts widely apart (RK. Patterson, 
‘Trish Naturalist,’ 1892, p. 19). Yet, at the most, it must 
be regarded only as a wanderer to our shores, generally 
appearing in immature dress, singly or in couples. It is 
very rare on inland waters. 
Though often described as being shy of approach, I 
have seen immature birds comparatively tame. Thus on 
September 14th, 1894, whilst shore-shooting on the marshes 
of Dublin Bay, in company with Dr. N. H. Alcock, an 
immature Glaucous Gull flew twenty yards over our 
heads, when my companion immediately fired and brought 
it down. This specimen, now preserved in the Science 
and Art Museum, Dublin, was distinctly less fearless than 
hundreds of Common and Herring-Gulls, which seldom 
ventured within range, even before a shot was fired. Again, 
on March 18th, 1901, I saw another in similar plumage,
