Breeding-place of the Little Auk. 
In two places at least on the S.E. and S.W. of the island, 
where the cliffs are much lower and there are large boulders 
on the shore, there are breeding-places of the Little Auk. 
The birds look like miniature Razorbills in flight. They are 
much shyer than the Puffins, and, if once disturbed, it is a 
long time before they will settle again even if the observer 
remains hidden. I do not think there can be many breeding- 
on the island, as I watched them for a long time and never 
saw more than six flying at one moment, and each time that 
I returned to the same place I saw the same number of

of thousands of sea-birds in the breeding-season, even the 
lower cliffs, which are easily acessible and in some places 
little more than banks, are tenanted by them. Fulmars, 
Razorbills, Black Guillemots, Kittiwakes, and Briinniclds 
Guillemots are the most numerous. The last are easily 
distinguished from their more southern relatives by the 
light line at the edge of the upper mandible and their 
blacker colour.
