know of the latter that it breeds in Central Siberia, and winters 
in North-western India, so that its migrating line is probably 
north and south, whereas the migration of C. cornix is east 
and west. 
Habit..— The ways of the Hooded, or “ Danish ” Crow, as 
it is often called by the marshmen, are best observed in 
England on the east coast after the season of migration, when 
the bird is plentiful in the marshes and on the shores.' The 
favourite food of the Hooded Crow seems then to consist of 
cockles. When the bird finds a difficulty in opening one of 
the latter, it flies up into the air and lets the mollusc fall 
upon a rock or hard ground, so as to break the shell. In 
Scotland and parts of the United Kingdom where this Crow is 
resident, it enjoys, with the Carrion Crow, the hatred of every 
gamekeeper for the damage it does to the eggs of game-birds 
which it devours wholesale, and we have ourselves seen the 
ground under a Hooded Crow’s nest strewn with the egg- 
shells of Grouse. It is quite as destructive a bird as the 
Carrion Crow, if not more so. 
West.— This is a solid structure, and is placed on a tree or 
rock, being often built on cliffs. It is of the usual Corvine tvpe 
being largely composed of twigs, and branches, coarse roots 
moss, and wool, with a few feathers. 
Eggs. From three to six in number, green or greenish blue 
generally clouded with brown spots and mottlings and overlaid 
with larger mottlings of greenish brown. Sometimes, even in 
the same clutch, will occur eggs of a nearly uniform greenish 
blue, with the markings nearly obsolete. Axis, rce-i-g-
