GLAUCOUS GULL. 
77 
broken bars of pale brown ; the secondaries white at the ends 
and mottled with brown like the back; the primaries isabelline, 
ashy-white on the inner webs, and with slight remains of brown 
markings at the ends; ujjper and under tail-coverts white, 
distinctly mottled with brown ; the tail-feathers ashy-brown, 
mottled on the edges with white ; crown of head ashy-brown, 
slightly darker than the mantle, and streaked like the side of 
the face ; under surface of the body ashy-brown, the throat 
whiter, streaked with ashy ; under tail-coverts white, barred 
with light ashy-brown ; the under wing-coverts and axillaries 
ashy-brown like the breast ; hill ochre-yellow to the angle, then 
blackish to the tip ; tarsi and toes brownish. 
Mr. Saunders says that, after the moult of the next year, both 
the upper and under surfaces are much lighter, and pale grey 
feathers begin to show on the mantle, the outer primaries being 
all but white. In immature birds the mottlings of the upper 
surface gradually disappear, and for a short lime the bird 
appears to be creamy white (in which phase of plumage it has 
received the name of L. hutchind). At the subseciuent moult 
the pearl-grey mantle is assumed, but the new tail-feathers 
show some faint brownish mottlings until the next year. 
Nestling. — Of a stone-grey colour, slightly tinged with yellow- 
ish-buff below ; the back mottled with ashy-brown, and the 
head spotted with black. 
cnaraoters. — The Glaucous Gull is distinguished by its large 
size, white head and tail, and especially by its white quills, 
with a faint shade of grey at the base. Only two Gulls of the 
white-winged group answer to this latter character, the Glaucous 
Gull and the Iceland Gull. 
Eange in Great Britain. — This is an Arctic species, which visits 
us in winter only, and is then chiefly noticed in the northern 
parts of the British Islands. It is a more or less regular 
visitor, sometimes occurring in numbers, but less often on the 
west and south coasts ; young birds predominating. 
Range outside the British Islands. — A circumi)olar species dur- 
ing the breeding season, wandering southwards in winter to 
the Mediterranean, Black and Caspian Seas ; also recorded 
from Japan. In America it visits the Great Lakes, and reaches 
to Bermuda and Florida, and on the west coast of California
