BRUNNICH’S 
GUILLEMOT. 
(Uriel loinvia.) 
This species has quite a differently shaped bill from the 
Common Guillemot and might almost be generically separated: 
it is much stouter and has an enamelled appearance near the 
gape. The colour, too, is different from that of U. troile, as 
the throat and sides of the face and neck are of a chocolate-brown colour, which 
conti asts with the black of the upper surface. It is only an occasional winter 
visitor to Great Britain, being an inhabitant of the Arctic Regions, nesting in 
Spitsbergen and Greenland, as well as on the Pacific side of North America. The 
single egg is laid on the shelves of rock, and is subject to great variation in colour. 
In habits the species resembles the Common Guillemot.

THE BLACK 
GUILLEMOT. 
(Cepphus grylle.) 
This is a much smaller bird than the preceding, and has a 
smaller bill. The summer and winter plumages are also very 
distinct, though it would appear that very old birds retain their 
black dress throughout the winter season. It can always be 
distinguished by its bright coral-red feet. Young birds are at first white-breasted, 
and when the black dress has been donned, the}' can always be told by the black ends 
to the wing-coverts, these being always pure white in a fully adult bird. The Black 
Guillemot breeds in the north of Scotland and in Ireland, and is found on the coasts 
of Northern Europe, the Faeroes and Southern Greenland. It is generally seen in 
pairs, but occasionally small parties may be observed, even during the breeding- 
season. The eggs are two in number, and are generally placed in a narrow cleft of 
rock at some distance from the opening, so that they are by no means easy to reach. 
There is no nest, and the eggs, which measure from two to two-and-a-half-inches in 
length, are white with black spots and underlying purplish-grey blotches or spots.
