the Rooks to desert a rookery in the same grove, which they had 
previously frequented for many years. 
2. C. Corone (Crow). 
We have often been much amused with the sagacious instinct 
of this bird, and of others of the same genus, in getting at their 
prey. In the winter season they frequent the sea-shores during 
the ebb tide in search of muscles and other shell-fish. As soon 
as the bird has found one, it flies up almost perpendicularly into 
the air, with the fish in its beak, and lets it fall on the stones in 
order to break its shell. The bird quickly follows the falling 
booty, and devours it. 
The eggs of the Crow are subject to vary both in shape and 
colour. Two of them in our possession, taken from the same 
nest, differ considerably ; one being of a pale green with very 
few small spots, and the other almost entirely covered with large 
dusky spots. 
3. C. Cornix (Hooded Crow). 
The Hooded Crow made its appearance in this country in the 
year 1816 as early as October 9th. "They are very common in 
Suffolk on heaths. Sometimes they will approach the habita- 
tions of man, and feed upon the carrion preserved for dogs. 
This species is rather numerous in the neighbourhood of Yar- 
mouth during the winter, feeding among the ooze at low-water; 
it is also frequently seen on the road between that place and 
Norwich. | E 
4. C. frugilegus (Rook). 
"The eggs of the Rook are very good to eat, and by some per- 
sons have been thought equal to those of the Lapwing. Like 
those of the Crow, they are sometimes seen of a pale green,
