RING-NECKED DUCK 
150. Marila collaris. 17 in. 
Male with a narrow chestnut neck ring; head glossed 
with purple; back black; chin white: bill blackish, with 
a bluish band near the end; eye yellow. Female with 
white cheeks, eye ring and region about the base of the 
bill; otherwise similar to the female of the Redhead, 
but smaller. 
These ducks are usually met in flocks of from one 
to three dozen, the same as the preceding two _ black- 
headed ducks. Their flight is very rapid, and they are 
equally agile when in the water. They are seen on 
the Atlantic coast only in winter, and remain just as 
far north as the water remains open. 
Notes.—A low grunting ‘“quanck.” 
Nest.—Of grasses and feathers in marshes and on 
bogs. The 6 to 10 eggs are grayish-white (2.25 x 1.60) ; 
June. 
Range.—Breeds in the interior of Minnesota north- 
wards; winters throughout the United States.
