Here's the iray version of my Spruce Grouse in the new Gamebirds update... The Spruce Grouse is found in Canada and portions of the northern United States. Its distribution largely coincides with boreal coniferous forest; linked mainly with pine, spruce and fir trees. During winter, they eat mainly pine or spruce needles or both, constituting up to 100%. Summer and autumn food of adults is mostly growing tips, leaves, flowers and berries of blueberry, crowberry and other ground vegetation. In spring, females concentrate on foods rich in protein, thus conifer foliage, flowers, fruits, and foliage of ground plants, grit, and arthropods, with large clutches associated with high intake of two especially preferred foods, flowers of trailing arbutus and spore capsules of Polytrichum mosses. 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. Males give territorial displays include fanning and sweeping of the tail, and wing claps but unlike some other grouse, the Spruce Grouse does not have throat-sacs that inflate during the displays.
