shaped crext with a large white fan-,shui>ed patch, while tlie fhiclc 

 has an vniiuirh-d, grayish hnnvn head. But in the wood chick.s 

 the drake has red eyes, a pnqdish-ehestniit breast spotted with 

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

 head streaked ivith white; while 

 the gray-headed female has a 

 irhlte eye patch streahlncj Tjack- 

 ward. The white lines on the 

 head are enough to distinguish 

 both sexes of wood duck from 

 both mergansers and golden- 

 eyes. 



Redhead: Mar ila ameri- 

 cana. — Though not a common 

 migrant in the park, the red- 

 head has been noted by 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 : MarUa valisineria. — 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 

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

 siderable numbers. On April 21, lOlS. jNIr. I>ailey saw a few small 



flocks on Lake McDonald, readily distin- 

 guished from the surrounding flocks of 

 smaller ducks. 



ScATjp Duck: Marlla marlla. — 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 fafl of 1887 Dr. 

 Grinnell found them abundant on the 

 Lower St. Mary just outside the park. 



Lesser Scaup Duck : Marlla affinh. — 

 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.
