Seasonal Foods and Chemical Analysis of Winter Diet of Alaskan Spruce Grouse
Ellison L. 1966. Seasonal Foods and Chemical Analysis of Winter Diet of Alaskan Spruce Grouse. The Journal of Wildlife Management. 30(4):729-735
Volumetric and weight analysis of the crop contents of 237 Alaskan spruce grouse (Canachites canadensis) showed that the winter diet was largely spruce (Picea spp.) needles and that during other seasons berries and leaves of several species of Vaccinium were important foods. Chemical analysis of black spruce (P. mariana) and white spruce (P. glauca) needles indicated that black spruce had a higher fat and caloric content than white spruce, but a lower ash content.
