However to achieve your goal this is what you need to do. Get a list together of a bunch of places where you want to try wild brown streams. Then go onto Google in the vicinity of those streams and look for clearcuts. They will show up very well. One clearcut is hit/miss. Several clearcuts in an area separated by patches of mature forests are best. That gives you birds trading back and forth between good and marginal habitat. You won’t know exact cover and food availability until you put boots on the ground. You will shoot a grouse doing that.
