Corvus corone. The Carrion-Crow. 
A very common resident, and becoming more so. It is to 
be found nesting on the low trees on the island, but more 
commonly, owing no doubt to the scarcity of trees, it nests 
on the outlying rocks, often close to the ground and not far 
above high-water mark. Curiously enough it does not 
appear to make much use of the safer situation afforded by 
the high cliffs of the southern shore, although a few pairs do 
nest there. The birds are more numerous in the autumn and 
winter months, but this may be due to the young birds 
remaining with the family until the approach of the next 
breeding-season, when they probably depart to make a home 
for themselves elsewhere. These birds are very bold during 
the breeding-season and frequently take toll of young 
chickens. 
Corvus cornix. The Hooded Crow. 
I saw one of these birds on the 20th of November, 1918, 
and a flock of ten—the largest number I have seen together 
on the island—on the 30th of October, 1919, and another on 
the 15th of November, 1919. L. tells me he sees some 
during the month of October every year, and that they 
usually arrive just before the first Woodcock, their appear¬ 
ance being looked upon by the islanders as an indication 
that Cock may be expected. Several Cocks were shot on 
the day after I had seen the flock of ten Crows mentioned 
above. Mr. Cecil Smith says : u The Hooded Crow can only 
be considered an occasional autumnal and winter visitant— 
Mr. MacCulloch writes me word that the Hooded Crow is 
a very rare visitant, and only, as far as he knows, in very 
cold weather ; and, he adds, it is strange that we should see 
it so rarely, as it is very common about St. Malo.” Neither 
Langlois nor myself, with the exceptions of the two birds 
mentioned above as seen in November, and which I prefer, 
owing to the extreme mildness of the season, to regard as 
late migrants, have seen this bird in Alderney during the 
winter months, even in hard weather, and it must therefore, 
at present, be considered as a bird of passage only, although
