f^haped crent with a large white fun-xhaped patch, while the duck 

 has an unmarked, grayish brown head. Bnt in the wood duck.-^ 

 the drake has red e,yes. a piirplish-chestnnt breast spotted with 

 white, a heavy green and purple drooping crest and the sides of the 

 head streaked with white; while 

 the gra3'-headed female has a 

 white eye patch streahlng hack- 

 ward. The white lines on the 

 head are enough to distinguish 

 both sexes of wood duck from 

 both mergansers and golden- 

 eyes. 



Redhead: Mar da ameri- 

 cana. — Though not a common 

 migrant in the park, the red- 

 head has been noted b}' Mr. Ste- 

 venson. Mr. Gibb, and ]Mr. Gird. 

 In October, 1887, Dr. Grinnell 

 found it abundant on the St. 

 Mary Lakes. On April 21, 1918. 

 Mr. Bailey saw a pair out in the 

 middle of Lake McDonald. 



Canvas-back : Marila valisliieria. — Mr. Gibb reports seeing the 

 canvas-back during migration, and Mr. Stevenson reports it from 

 Duck Lake east of the park in fall. In October. 1887, Dr. Grinnell 

 found it on the Lower St. Mary during bitter cold weather in con- 

 siderable numbers. On April 21, 1918. Mr. Bailey saw a few small 



flocks on Lake McDonald, readily distin- 

 guished from the surrounding flocks of 

 smaller ducks. 



Scaup Duck: Marila marila. — On 

 April 21. 1918. Mr. Bailey found these 

 large scaups with light-gray backs and 

 bright blue bills scattered over Lake Mc- 

 Donald from one end to the other in both 

 large and small flocks, aggregating at 

 least hundreds. In the fatl of 1887 Dr. 

 Grinnell found them abundant on the 

 Lower St. Mary just outside the park. 



Lesser Scaup Duck : Marda afjrnis. — 

 Mr. Bryant told us that the lesser scaup, 

 whose head is glossed with purple instead of green, passes over Lake 

 McDonald, and Mr. Stevenson writes that a duck which he takes for it 

 occurs in the park during the fall months in large flocks. Dr. Grinnell 

 in 1887 found it abundant on the prairie lakes adjoining the St. Mary 

 Lakes region, and when these froze up on the Lower St. Mary Lake.
