Unlike deer where White Acorns are the "Cherry" on their sundae.Grouse will eat what ever is available.Other then checking the crop.A great late season approach is start hunting about 8am.By then the birds are out to feed after a long cold nite and most active again just a hr or so before dark packing their bellies with food for another long cold nite.Also in the late season,hunt the sunny sides of the slopes.Many times you'll find birds getting those last warming rays of sunshine while they are feeding before nite falls.Take care Jackson..
