Major W. It. Thompson on the [Ibis, 
entrance. I have not before had the opportunity of studying 
this bird at close quarters, and cannot say if this is its usual 
method, but have always thought that it fell vertically on to 
its prey. 
The only time I have seen this bird here in any numbers 
was on the 19th of May, 1920, when a flock consisting of 
nine adults and two immature birds were observed fishing- 
close to the shore. At this time, it was reported by the 
fishermen that large quantities of small pollack were off the 
coast, and a herd of at least fifty porpoises (Delpliinus 
phocama ) of all ages was constantly patrolling round the 
island, so there were certain abnormal conditions to account 
for this, and the same conditions obtained still a week later, 
when large numbers of gannets were reported between 
Alderney and Guernsey. 
Anser anser. The Grey-lag Goose. 
L. tells me that this bird is an occasional winter visitor, 
coming to the island during hard weather, and usually in 
' small trips of six or seven individuals. A number have been 
shot at various times. I have not myself observed it, but the 
winters I have passed on the island have been comparatively 
mild. 
Anser brachyrhynchus. The Pink-footed Goose. 
I killed one of these birds during a strong north-east gale 
on the 19th of December, 1913. It was by itself and rose 
from the rough grass bordering Longy Bay. 
Branta bernicla. The Brent Goose. 
Small trips of these birds are often seen off the rocks 
during the winter months. A winter visitor, but varying 
much in numbers according to the severity of the weather. 
Anas boschas. The Wild Duck. 
A winter visitor in small numbers and during severe 
weather only. They do not remain long, as they are almost 
immediately shot at. I have observed it occasionally in the 
autumn as a bird of passage.
