though not especially large, includes some species not ordinarily eaten 

 by other birds and for that reason is specially important. It is one of the 

 few birds that will eat the potato beetle. 



FAMILY TETRAONIDiE. GHOUSE. 



The Grouse have their nostrils hidden in feathers that occupy an 

 ntrusive space in the base of the bill at the sides (Figure 29, p. 23). The 

 tarsus is either completely or partly feathered, in the Ptarmigan the 

 feathering includes the toes. The toes when unfeathered, are bordered 

 on each side by a small fringe composed of individual horny scales or 

 pectinations (Figure 28, p. 22), which are shed in midsummer. The 

 Grouse comprise the bulk of our upland game birds and are great 

 favourites of sportsmen. The sexes are alike or nearly so, and except in 

 the Ptarmigans show slight seasonal variation in plumage and do not 

 usually migrate. The Ptarmigan,which directly reverse each of these 

 statements, are so well characterized otherwise that no confusion is prob- 

 able. All species nest on the ground, making little preparation for the 

 eggs. They lay unusually large sets of eggs, six to eighteen, and the 

 young, chicken-like, follow the parent as soon as out of the shell.

 Du CANADA. CanochUes canadensis. L, 15. Plate X A. 



Distinctions. Easily distinguished by colour, etc., from the Ruffed Grouse which 

 is about the only species in eastern Canada that can possibly be mistaken for it. In the 

 extreme west there are forms that closely resemble it. 



Field Marks. General bluish colour of the male. Absence of ruff or specialized neck 

 feathers and the presence of the striking red comb over the eye, present in both sexes but 

 more conspicuous in the male. 



Distribution. Through the northern coniferous wooded regions of Canada, resident 

 wherever found. 



SUBSPECIES. The Spruce Partridge is divided into several geographical races, two 

 of which, the Hudsonian Spruce Partridge Canachites canadensis canadensis, the type form, 

 and the Canada Spruce Grouse C. v. canace, occur in eastern Canada. The former occupies 

 the Labrador peninsula and the more northern ranges and the latter New Brunswick, 

 southern Ontario, etc. They are too similar, however, to be differentiated in a popular 

 work. 



A northern bird of the spruce woods. Its super-confiding nature has 

 given it the popular name of "Fool-hen" as, where not much disturbed, 

 it can often be killed with a stick or with stones. Owing to its feeding 

 largely upon spruce or evergreen buds its flesh is too strong for the ordinary 

 civihzed palate. 



Economic Status. Being of northern distribution and living in the 

 evergreen forests, it has no economic influence.

 Bonasa umhelhis. L, 17. Plate X B (Feet and biU, Figures 27, 28, p. 22). 



Distinctions. The Ruffed Grouse, with its prominent soft, black ruff at the sides of 

 the neck, large fan-shaped tail, and eye-Uke spots on the rump and lower back cannot 

 well be mistaken for any other spfecies. 



Field Marks. Large size and fan-shaped tail. 



Distrilmtion. The Ruffed Grouse is distributed throughout the wooded areas of Canada 

 north to the tree limits. 



SUBSPECIES. Several geographic races of the Ruffed Grouse are recognized. 

 The type form is of southern distribution and is replaced in eastern Canada by the Canada 

 Ruffed Grouse Bonasa umhellus togata, characterized by a greyer or less red coloration.
