bluff facing the ocean and awa}' 
frf)m the main rookeries of nnirres. 
From the appearance of the nests 
they had been used for many years. 
On the accompanying map the 
rookeries as noted in 1887 aredesig- 
nated by numbers, while those of 
1903 are indicated by letters. 
(1) Murre Bridge or Great 
Arch Rock was formerly occupied 
along the whole ridge. Colony 
has decreased somewhat. 
(2) A small colony of Farallone 
cormorants { Phalacrocorax dilophns 
albociliatus) has disappeared. 
(3) This great murre rookery 
on the divide of West Knd was 
one of the largest on that section of 
the island. By standing in a gap 
or slit of the ridge one could look 
down upon hundreds of cackling, 
bol)bing, murres going to and com- 
ing from the .sea, after feeding hours. 
Tliey seem to have regular times 
of the day, when incubating, to 
relieve each other. This rookery 
is much reduced, and the birds are 
very wary. All the island birds 
have grown more wild, probably 
because a dog, which did not used to be kept, now accompanies the men and chil- 
dren wherever they go, and causes the birds to be continually moving on and off 
their nests. This 
is particularly the 
case about the 
southern part of 
the flats and rocks 
below the keepers’ 
dwellings. Where 
one could go out 
ten yards beyond 
the house among 
the rocks and .study 
the birds content- 
edly brooding their 
eggs, now none are 
seen, unless it be 
petrels and anklets 
among the stone- 
walled trails, or in 
burrow's. looking over fisherman s bay to sugar loaf island
