HIS differs from the crow in the form 
of its bill; which is ftraiter, (lender- 
er and weaker; a ftrong-bill being un- 
necefiary to a bird that feeds only on grain and 
infers. The noftrils, chin, and Tides of the 
mouth are white and bared of feathers, by often 
thrufting the bill into the ground in fearch of the

1HE bill of this fpecies agrees in Ihape 
with that of the rook ; to which it 
bears great fimilitude in its manners 5 
lying in flocks, and feeding on infedfs. In Great 
Britain it is a bird of paffage : vifiting us in the 
leginning of winter, and leaving us with the 
voodcocks. They are found in the inland as well 
is maritime parts of our country ; in the latter 
hey feed on crabs and fhelfifh. They breed in 
Sueden , and build in trees, commonly in alders ;

is twenty-two ounces : the length twenty-two in¬ 
ches ; the breadth twenty-three. The head, un- 
derfide of the neck, and wings are black glofled 
over with a fine blue : the breaft, belly, back, and 
upper part of the neck, are of a pale afh color : 
the irides hazel: the legs black, and weaker than 
thofe of the rook. The bottom of the toes are 
very broad and flat to enable them to walk wdth-> 
out finking on marfhy and muddy grounds, where 
they are converfant. We do not know that they 
breed in any of the Brzt/ft ifles, except Shetland 5 
being the only fort of crow found there.
