CARRION-CROW. 543 
both these birds are generally larger than those of the Rook and smaller 
than those of the Raven. 
When the young are hatched, the old birds become even more trouble- 
some to the gamekeeper and the hen-wife; and until they are able to fly, 
the neighbourhood is scoured in search of food for them. The Carrion- 
Crow only rears one brood in the year; and the young are soon left to 
forage for themselves. Although the Carrion-Crow is a resident in this 
country, its numbers are evidently increased in autumn by birds from 
Holland. In Norfolk they are said to be regular spring and autumn 
migrants; and it is only in this character that they probably appear 
in parties on our eastern coasts. 
The Carrion-Crow has the entire plumage black, glossed on the upper 
parts, wings, and throat with purple and green. Bill black; legs, feet, 
and claws black; irides brown. The female does not differ from the male 
in colour; but young birds differ from their parents in having no gloss on 
the plumage. The Carrion-Crow may be distinguished from the Rook by 
its much stouter bill, by the prevailing green instead of violet gloss to the 
plumage, and by never having the base of the bill denuded of feathers. 
In the Carrion-Crow the nostrils are always covered with thick bristly 
feathers.
