2 THE AUKS 



in smaller numbers. As a rule, its breeding-places are also higher up on the cliffs 

 than those of the kittiwake, below those of the puffin, and often overlapping 

 the vertical range of the guillemot. Outside the British Isles it also breeds 

 in the Faeroes and Iceland, and along the Norwegian coast from Stavanger Fjord 

 northward to the North Cape (Collett), east of the Varanger Fjord in Russian 

 Lapland (Pearson and Pleske), and perhaps also on the Murman coast, while, 

 according to Buturlin, it is found in the Kola Peninsula and the White Sea to 

 Onega Bay. Southward it is found on the coasts of Brittany, as well as on 

 Bornholm, Helgoland, Gotland, and other localities in the Baltic, even in the Gulf 

 of Bothnia and along the coast of Finland. On the west side of the Atlantic it is 

 found from 73 N. on the west coast of Greenland along the coast of Labrador 

 south to Newfoundland and the Bay of Fundy. Its winter range extends from the 

 North Sea and English Channel southward to the Bay of Biscay and the Straits of 

 Gibraltar, while in the Mediterranean it has occurred as far east as the Adriatic 

 Sea and Malta. [F. c. B. j.] 



3. Migration. Resident, in that examples may be seen in territorial waters 

 all the year round ; but our information regarding the species' movements is very 

 incomplete. From late in March till early in August the birds are at their breeding- 

 places, but for the rest of the year they remain at sea. In rough weather they 

 become numerous close inshore, and their bodies are frequently thrown up on the 

 beach ; sometimes they are seen in estuarine waters or even inland. But the 

 greater proportion of the birds are out at sea ; little information exists as to how 

 far they go, and we can only conjecture whether British waters are visited by birds 

 from farther north. There is some evidence that our own birds remain near our 

 coasts during the autumn and move southwards in December, after which it is 

 principally young birds that are to be found (cf. Ussher and Warren, B. of Ireland, 

 1900, p. 357). [A. L. T.] 



4- Nest and Eggs. No nest is made by the razorbill : the egg is laid on 



the bare rock, but if possible in some sheltered crevice, or, at any rate, on a much 



overhung ledge, so that it is often difficult to reach. (PL xxxix.) Apparently in 



places where crevices in the rocks do not exist, it breeds in holes like the puffin (cf . 



H. J. Pearson, Three Summers among the Birds of Russian Lapland, p. 16), and more 



.. frequently under boulders, as at Scilly (see p. 15). Only one egg is laid, less pyrif orm 



' arid more conical in shape than those of the guillemot, and showing less variety 



' ill colour' and markings. The ground-colour usually varies from white to yellowish, 



pale brownish or reddish, blotched, spotted, and smeared, often in the form of a
