BRITISH BIRDS.

caught in the fens of Lincolnfliire during the win- 
ter feafon^ and fold in the London markets^ where 
they and the female Wigeons are indifcriminately 
called Dunbirds, and are efteemed excellent eating. 
It has not yet been difcovered whether any of them 
remain to breed in England. 
The Pochard is of a plump round fhape, and its 
walk is heavy 5 ungraceful, and waddling; but 
when on the wing, they fly with greater rapidity 
than the Mallard, and in flocks of from twenty to 
forty, commonly in a clofe compact body, whereby 
they may be eafily diftinguiflied from the triangu- 
lar lhaped flocks of the Wild Duck, as well as by 
the difference of the noife of their wings. 
The few attempts which have been hitherto made 
to domeflicate this fpecies have failed of fuccefs. 
They do pretty well where they have plenty of wa- 
ter, but it is faid that they cannot bear walking 
about on hard pebbly grounds.
