About the Sooty Grouse#
The sooty grouse (Dendragapus fuliginosus) is a species of forest-dwelling grouse native to North America's Pacific Coast Ranges. It is closely related to the dusky grouse (Dendragapus obscurus), and the two were previously considered a single species, the blue grouse.

Field-craft tips#
- Lek displays at dawn (spring) — use a blind and arrive before light.
- Shoot from ground level; game birds flush suddenly, so keep the shutter fast and AF in continuous mode.
- Sightings peak in July and August, which is when you'll have the most chances.
Ethics#
- The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
- Stay on trails, respect closures around nests, leks, dens and haul-outs.
- Avoid playback and baiting in sensitive seasons; never bait predators.
- Don't share precise locations of rare, nesting or roosting animals publicly.
