I have hunted up there for grouse and woodcock. My advice is to try and beat the moose hunters. I have hunted before and after the rifle hunt and seems to be more birds before the moose guys show up. The place I stayed provided me a map with some information to point me in the right direction. Endless atv/logging roads. If you have a decent dog you will certainly find birds. Good Luck! and if you would like more information please PM me.
Happy Hunting!
