I was doing a bit more research into winter time grouse foods when I came across this: Winter Food Habitats of Ruffed Grouse in Young Aspen Stands. This paper is based on finding from a 1972-1973 study of 10-15 year old clear cuts in Oneida County, Minnesota.
As a hunter, I usually don’t get see grouse doing there own thing. Here are few videos of them doing just that. It’s amazing how many berries they can stuff into their crops.
I spend a lot of time in the woods chasing grouse. But here are a video of something I’ve never see: grouse feeding. It’s pretty interesting and worth sitting through. There are some great close up towards the end.
