Gasaway, W.C., 1976: Volatile fatty acids and metabolizable energy derived from cecal fermentation in the willow ptarmigan. The 35 willow ptarmigan (Lagopus lagopus) were shot in Alaska in April. Willow buds and twigs were 93% of crop contents, and the buds were the most nutritious food item by chemical analysis. Mean length of caecum was 100 cm for females, 107 for ma...

Mortensen, A.; Blix, AS., 1986: Seasonal changes in resting metabolic rate and mass-specific conductance in Svalbard ptarmigan, Norwegian rock ptarmigan and Norwegian willow ptarmigan. Resting metabolic rate was measured at different ambient temperatures in Svalbard Ptarmigan, Norwegian Rock Ptarmigan and Norwegian Willow Ptarmigan at different times of the year. All three species/subspecies exhibited a significant decrease in m...

Mortensen A.; Tindall A.R., 1981: Cecal decomposition of uric acid in captive and free ranging willow ptarmigan lagopus lagopus lagopus. Urine entering the ceca of birds contains significant amounts of uric acid. The discovery of great numbers of bacteria utilizing uric acid in the ceca has encouraged the discussion about N recycling in birds. Cecal decomposition of uric acid in wi...

Mortensen A.; Tindall A., 1981: Cecal synthesis and absorption of amino acids and their importance for nitrogen re cycling in willow ptarmigan lagopus lagopus lagopus. The willow ptarmigan has 2 large ceca housing dense populations of microorganisms. Urine, containing uric acid, is transported from the cloaca into the ceca when these are filled. Here the uric acid is rapidly broken down, suggesting that the ceca...

Diets containing 22.2% of large (1.31 x 1.31 mm-5 x 5 mm) (LPD) or fine (<0.62 x 0.62 mm) (FDP) particles of oak leaf meal were fed to 7-month-old male Japanese ptarmigans for 8 days. Daily DM intakes in ptarmigans fed on LPD and FDP were 44 an...

Between 1996 and 1998, ruffed grouse, spruce grouse, willow ptarmigan, and rock ptarmigan harvested by hunters in Québec were examined for lead contamination. On examination of the gizzards of these birds, lead shot was found only in ruffed grous...
