256 STATE AGRICULTURAL COLLEGE BULLETINS. 



Genus BONASA Steph. 



lS(>-3()()-(o(».">). IJoiiasa iimhcllns (Linn.). *Rufped Grouse; "Partridge,'' in 

 Michigan, "Pheasant," south. 



Raffed Groase, natural size. 



Very common, though decreasing in number; throughout the entire state; "still 

 abundant about Ann Arbor '* (Dr. J. B. Steere); " abundant at Bay City where many 

 are killed by sportsmen " (N. A. Eddy); " common at Iron Mountain " (E. E. Brew- 

 ster); "very common at Keweenaw Point" (Kneeland); "not seen on Mackinac 

 Island, though common on the mainland north and south " (S. E. White); " very 

 common resident at Albion and St. Joseph, and common at Palmer, Marquette 

 Co., where it is less shy than in the Southern Peninsula" (O. B. Warren); "com- 

 mon at Port Sanilac through the year " (W. A. Oldtield); breeds; nests in June, on 

 the ground, nests said to be often concealed by logs, etc.; "I never find them so" 

 (Prof. Ludwig Kumlein); "always covers eggs with leaves before leaving the nest" 

 (J. B. Purdy); I have always found the nests of eggs entirely exposed; eggs six to 

 fifteen, usually ten to twelve, creamy white to buff, occasionally spotted with fine 

 reddish dots; seen through the year; excellent game bird; occasionally fly into 

 houses in autumn through windows. This bird is known by the drumming of the 

 male with its wings, which may be heard for a long distance. This bird eats 

 berries, nuts, especially beech nuts, and insects. In the autumn it eats many 

 grasshoppers and such caterpillars as the oak caterpillar. Edema albifrons. My 

 son, A. B. Cook, thinks that they never cover their eggs, except as they accidentally 

 sweep the leaves over the eggs as they take wing. The drumming for which this 

 bird is noted is probably caused by the wings striking the air.
