ROUND-CRESTED DUCK. 
coverts are black, with deep white tins : the 
lesser coverts of the wings are of a light ash- 
colour, bordered round the ridge on the upper 
part of the wing with dusky. The breast, 
belly, and covert-feathers beneath the tail, are , 
white. The black of the back breaks into 
the white in angles at the lower part of the 
neck. The sides of the belly, and the sides 
under the wing, are of an orange-coloured 
brown, marked with fine dusky transverse 
lines. The legs and feet are, like those of 
Ducks, of a dusky colour. The inner toes 
have small lateral webs on their outsides : the 
back toes have webs on their bottoms.

1759, accompanying these birds, he informs 
me, that they are all Birds of Passage : that 
they arrive in Pennsylvania, in November, 
from the north ; and continue till Aiarch,

in the settled parts, arc now no more to be
