Any tips or tricks for hunting these birds?
Not sure where you'll be hunting for them, but they eat almost 100% earthworms, so you need to find wetter ground which will be ZERO problem this year[hihi]
Idealhabitat here in north Jersey or in NY and PA where I typically hunt them would be younger stands of aspen with goldenrod growing underneath. They fear predators from above like hawks, so they like that two layer cover. But they will also be found under our invasive Autumn Olives, young hardwood forests, apple trees, etc. If you have younger pines mixed in to some of the above, look for them resting under the pines because they offer great cover from winged predators. On sunny afternoons, you might can them on the sunny side of the hills loafing before flying to a new cover at dusk or during the night.
They hold great for pointing dogs, which is a real bonus because grouse most often will not. And you sometimes get close-in points depending on wind direction, humidity, etc. I've had my old Brittany point one bird, it flew and I killed it, only to look back at him standing staunchly on point but looking slightly in a new direction. Second bird that didn't flush with the first bird. Sometimes you can find a bunch using the same covers, the dogs get excited and the shots come quickly. Toss in some grouse and there is no finer bird hunting IMO anywhere!
