This popular upland game bird is the largest of Oregon's three forest grouse.

It is well known for the distinctive hooting call emitted by courting males in the spring. This call is accompanied by an extravagant courtship display involving exposure of blood-engorged, featherless shoulder spots and eye combs, which are reddish to orange.

It is a common resident in coniferous forests.
