What do spruce grouse eat?

In winter, when only needles are consumed, the caeca (dead-end extensions of the intestines) and ventriculus (gizzard) increase in size to support digestion. The crop is also well developed: up to 45 cc of needles (about 10% of body mass) can be stored in the crop at the end of the day, to be digested over the duration of the night fast. Like other birds, spruce grouse consume clay, grit or small stones to help their gizzard break down food. Chicks under 1-week old feed on insects and other arthropods, then switch to berries and fungi until the fall, when they start feeding on needles. Birds captured while on the winter diet have been maintained several months without loss of weight, on only pine needles and grit and clay taken from where they were seen consuming it.

Overview

Breeding

Males are promiscuous; they disperse and advertise a territory that is visited by females for mating. Females are solely responsible for the rest of the reproductive effort though males have been known to stay with young chicks and seem to aid in keeping the brood together. For a nest, they scratch a depression in the ground in a bush or under a low-lying coniferous branch or fallen tree, away from other females and from the males' territories. The nest is lined with grasses, lea…
