A Ruffed Grouse in the brush or woods can be a devilishly hard bird to spot. I've seen hundreds of them over the years, but most were blurs that exploded under my feet and rocketed off through the forest. We can tell that this bird is a male, so we may be in for some action as it is the amorous season for grouse. The thick blackish terminal tail band on a female is somewhat broken and incomplete at the apex of the tail.
Ah! Out struts the grouse, to put on a display that is guaranteed to wow the grousettes! You can see how this species was dubbed the "ruffed" grouse - check out those manelike feather boas surrounding the bird's neck. When male grouse strut their stuff, they puff these ruffs up to incredible dimensions, flare the tail to its full glory, and stalk about in the manner of a displaying tom turkey.
