- Cool Facts
- Two distinct subspecies of Spruce Grouse exist. "Franklin's Grouse," D. c. franklinii, found in the southwestern portion of the range, in the mountains from Alberta southward, has an all black tail with small white spots on the feathers overlying it. The northeastern subspecies, D. c. canadensis, has a rufous tip to the tail and lacks white spots above the tail.
- The Spruce Grouse's crop can store up to ten percent of the bird's body weight in food, to be digested at night.
- The Spruce Grouse's gastrointestinal organs change with seasonal shifts in diet. In winter, when the bird must eat more food to maintain its mass and energy balance, the gizzard grows by about 75 percent, and other sections of the digestive tract increase in length by about 40 percent.
