558 GAME BIRDS OF CALIFORNIA 



decrease in the number of Buffed Grouse occurring in the eastern 

 part of the United States in 1907 was attributed by Forbush (1912, 

 pp. 380-382) and other observers to an unusual flight of Goshawks, 

 a raptorial species notably destructive to game birds. Of forty-eight 

 Goshawks dissected by one firm of taxidermists, twenty-eight Jiad 

 remains of Ruffed Grouse in their stomachs ; in another case thirteen 

 grouse were known to have been destroyed by hawks in one locality. 

 Another important agent in the destruction of Ruffed Grouse is fire, 

 when it sweeps brushy and forested areas. Sitting birds will often 

 remain on the nest until injured or even killed by the flames. 



C. F. Hodge (Anonymous, 1914) reports marked success in arti- 

 ficially rearing Ruffed Grouse. The young hatch readily and can be 

 raised with as much success as some domestic fowls. The adult birds 

 have to be kept in separate pens to prevent them from damaging one 

 another, especially at mating time ; and the species is, moreover, sub- 

 ject to one or two diseases which may give some trouble. On the 

 whole, artificial propagation in the ease of this species would seem 

 anusually promising of satisfactory results. 



Because of its forest habitat it is probable that the Oregon Ruffed 

 Grouse will not markedly decrease in numbers within its restricted 

 range in northern California, at least as long as the forests remain. 

 Nevertheless its condition as to numbers should receive careful con- 

 sideration and any marked reduction be compensated for by closing 

 the hunting season for a period, or by other appropriate means. The 

 matter of its artificial propagation should also be thoroughly investi- 

 gated and, if feasible under Californian conditions, encouraged. It 

 would seem much more desirable to increase the numbers and extent 

 of range of our native game birds such as the Ruffed Grouse than to 

 attempt to introduce and acclimatize eastern or foreign species.
