CORVIDE. 245 
THE HOODED CROW. 
Corvus cérNIx, Linnzus. 
This bird, often called the Grey or Royston Crow, is a regular 
and numerous visitor to England, especially the eastern districts, 
from October onwards; but as a rule it departs in spring, though 
instances are on record of its having remained to breed, and cases 
of hybridism with the Carrion-Crow are not infrequent in the 
north. In Wales it is rare, but in the Isle of Man it nests 
annually. On the mainland of Scotland it is only too abundant, 
predominating in the north and west, and becoming the represen- 
tative form in the Outer Hebrides, Orkneys and Shetlands. In 
Ireland also it is common, and increasing, especially in the south. 
The majority of the large numbers found in our eastern dist.icts 
arrive from the Continent, and apparently from Scandinavia. 
In the Feroes the Hooded Crow is resident, and it occasionally 
visits Iceland. In Scandinavia, Finland, Northern Russia, and East 
Prussia it is common, migrating from the higher latitudes in autumn, 
at which season large flocks pass over Heligoland and winter in 
Northern Germany west of the Elbe. These, as a rule, take their 
departure in March, although some occasionally remain to inter- 
breed with the Carrion-Crow. Colonies of the Hooded Crow are 
dotted about Central Germany, are frequent in Galizia, and extend
