FULIGULA FERINA AMERICANA: RED-HEAD DUCK. 315 



collar ; head and neck brown, but loral space, chin, and eye-ring 

 white. In size between the other two foregoing species of 

 Fuligula. 



Another spring and autumn visitant, not common. 

 This is its proper category, though it may be occasionally 

 found in winter, and is known to breed in Maine, where 

 Mr. Boardman has found it in summer, near Calais (Am. 

 Nat., v, 1871, p. 12 1). As to its rarity in Maine, how- 

 ever, see Brown, Bull. Nutt. Club, vii, 1882, p. 190. 



RED-HEAD DUCK; POCHARD. 

 FULIGULA FERINA AMERICANA (Eyt.} Cones. 



Chars. Male : head and neck chestnut-red, rich and pure, with 

 bronzy reflections. Body anteriorly, rump and tail-coverts, 

 black ; back mixed silvery-gray and black in about equal 

 amounts ; the dark vermiculations unbroken ; speculum bluish-ash. 

 Female : head plumbeous-brown ; black parts of the male dark 

 brown ; vermiculations less distinct. In both sexes, bill dull 

 blue with a black belt at end, broad and depressed, two inches or 

 less in length ; not rising high on the forehead, the nostrils 

 within its basal half; head very puffy, the forehead convexly 

 coming down to bill ; extent of red on the neck less than in the 

 canvas-back. Length about 20.00 ; extent, 29.00 ; wing, 9.00- 

 10.00 ; tarsus, 1.70. 



Chiefly a migrant, and rather rare.' It, however, 

 breeds in Maine, according to Mr. Boardman (Am. Nat., 

 v, 1871, p. 662). It is very frequently offered for sale as 

 canvas-back, but there should be no difficulty in dis- 

 criminating the two species by the shape of the bill and 

 the color of the head.
