This species is very abundant in most parts of the northern 
and middle divisions of Scotland, and its islands, but becomes 
rarer as we advance southward. In many parts of England 
it is found only during winter. It feeds on Crustacea, mol- 
lusca, fish, larv8B, worms, insects, young birds, small quadru- 
peds, and seeds ; nestles in rocks and on trees, laying from 
four to six eggs, an inch and seven-twelfths long, an inch 
and one-twelfth in breadth, pale bluish-green, with oblong 
and roundish spots of greenish-brown and pale purplish-grey.

The Book is generally distributed, being common in all 
the cultivated and partially wooded districts of Britain and ; 
Ireland. Unlike the preceding species, it is gregarious, often [ 
forming vast flocks, which breed together in tall trees, the * 
nestling places being termed rookeries. The nest is large, , 
composed of sticks, and lined with fibrous roots, long straws, , 
wool, and other substances. The eggs, four or five, an inch 
and ten-twelfths long, an inch and a quarter broad, light 
greenish-blue, blotched, clouded, spotted, dotted, or freckled 
with greyish -brown, greenish-brown, and light purplish grey. 
The young are hatched early in April. This species is more 
’^^ermivorous than those above described, feeding chiefly on 
larv8B, earth-worms, and insects, occasionally on grain, pota- 
toes, and other substances, and in very dry or snowy weather 
frequenting the sea-shore to feed on Crustacea and mollusca,
