"The Spruce Grouse trusts its camouflaged plumage even in open areas - they are often called 'fool hens' - and daring birds will casually cross logging roads in broad daylight."
And yes, that was exactly what happened. It looked like a small size rock in the middle of the gravel road until it started to move. At that point, it slowly sauntered across the road until it reached the grassy verge and then darted for cover. (And "no", I don't know why it was crossing.)
