This fpecies in fize or colour is fcarcely to be diftinguifhed from the com- 
mon crow; but the bafe of the beak and forepart of the head and throat are 
bare of feathers, and appear whitifh in the rook, which will fufficiently mark 
the difference of fpecies in thefe birds. 
Rooks are the moft plentiful birds of the whole genus in this kingdom, and 
are very fociable, living and feeding together in vaft numbers. They build 
their nefts on high trees; and moft of the venerable groves, that adorn old 
manfion houfes, have a community of thefe birds, called a rookery. ‘They lay 
four eggs, and the male feeds the female during the whole time of incubation. 
Their chief food confifts of infects; and it is the manner of their working in 
the ground after worms, and the larvee of beetles, which occafions the bafe of 
the beak and adjacent parts to be deftitute of feathers, for thefe parts are co- 
vered in young birds. 
The egg is reprefented at Fig. 3, Plate VIII.
