to my experience, one would not expect to find the cor¬ 
morant here except as a casual visitor, as the locality with 
its strong tides, deep water, and rough rock-bound coast 
is not suited to it. A cormorant’s natural habitats are 
shallow land-locked bays, and shallow muddy harbours and 
estuaries. 
Phalacrocorax graculus. The Shag. 
A common resident breeding here in some numbers, and 
as in most green water situations, taking the place of the 
cormorant. 
I cannot understand how Mr. Eagle Clarke failed to 
observe it here in September 1898, as I cannot recall having 
ever failed to find several when I wished to, either feeding 
in the tide-way, or, as is often their habit, obtaining their 
food from the seaweed on the rocks exposed at low water. 
Sula bassana. The Gannet. 
This bird is not often seen near the shore, although it is a 
regular visitor outside the breeding-season, and usually in 
winter. 
I11 December 1J912 an immature bird was found on the 
golf links here with a broken wing and was killed by the 
man in charge of the links. It had doubtless tried conclusions 
with a telephone wire. 
On the 8th of December, 1918,1 was so fortunate as to have 
under close observation for some time from a point of vantage 
on shore, an adult male of this species. It was fishing at the 
entrance to Longy Bay, and I was on the top of an old fort 
overlooking and within 150 yards of it. The water was 
extremely clear and the surface smooth, and I could distinctly 
see the bird’s movements under water. In one of its dives 
it turned through a considerable angle just beneath the 
surface, apparently by aid of its wings, and in order to follow 
its prey. On another occasion it entered the water almost 
horizontally at great speed, and moving rapidly just below 
the surface, either with its remaining velocity, or perhaps by 
use of its feet—it did not appear to use its wings—emerged 
from the water not less than 8 or 10 feet from the point of
