The only way in which a region can be made attractive to 

 Grouse is to provide dense thickets and thick pine groves for 

 shelter, and to cultivate or save from the woodman's axe the 

 plants from which the Grouse get most of their food. The 

 Ruffed Grouse will eat grain sometimes in winter, but is not 

 often attracted by it. 



A plentiful supply of winter berries, like the barberry, the 

 sumach and others which hang long on the stem, with such 

 evergreen plants as laurel and wintergreen, must be available.
