ground or on a rock, and the 
eggs are two or three in num-

of the Glaucous Gull, and 
measuring two inches-and-a-

in length. 
THE 
IVORY GULL. 
(Pagopliila eburnca.) 
This is 
a truly 
Arctic 
species 
snowy 
and is clothed in 
plumage throughout, in the 
adult birds, the young ones 
having some spots of greyish 
black. It usually occurs in the British Islands in winter only, and thirty specimens 
have been captured, the greater number of which have been taken in Scotland. The 
Ivory Gull nests in the Arctic regions of both Hemispheres, and wanders south in 
winter as far as New Brunswick in America, and the coasts of Britain and France in 
Europe. Its flight is described as being more like that of a Tern than a Gull. In 
Franz Josel Land Mr. F. G. Jackson tells me that he found it breeding in crowds 
near Cape Mary Harmsworth, the nest being merely a depression in the moss. The 
eggs are greyish-brown with blackish spots, and do not exceed two in number. 
Their length is from two-and-one-fifth inches to two-and-two-fifths. 
It is easy to distinguish the Kittiwake from all the other 
British Gulls bv the absence of its hind toe. It breeds in great 
KITTIWAKE. 
, , numbers 
(Kissa tridacty la.) 
on many 
of the headlands of Great 
Britain : it also nests in 
the extreme Arctic Regions, 
and it appears to be dis- 
tributed over the north of 
both the Old and the New 
Worlds. It wanders south 
in winter as far as the 
Mediterranean Sea, and 
down both the Atlantic and 
Pacific coasts of America. 
In the cold season it is often 
found in large numbers off 
The Kittiwake.
