Mrs. Cannon & I got our limits just outside of Chapleau. I found this year it was almost all grey's (rough). This is a good thing if you don't prefer the blacks (spruce). I find hunting greys is more fun because they're so skittish and prone to attempting escape.
We hunt yearly in this area. Historically, I found that the birds were mainly out in early mornings, and more inclined to sunny & cool mornings. Also, they mainly stuck to the trails. This year, however, it was completely different. We got birds in the snow, rain, sun, winds, clouds, mornings, afternoons, evenings. Haven't seen that up in this particular location before. Also, several were right out in the roads. Didn't see any flocks, either. The most we'd see is perhaps small groups of 3.
As an aside, I have cream of grouse soup in my lunch today!
