Monoterpenoid content of sage grouse ingesta
Journal of Chemical Ecology, 1989We tested the hypothesis that the monoterpenoid levels in the ingesta from various digestive organs of sage grouse are less than that expected from the big sagebrush leaves ingested. Results supported the hypothesis. Dramatic reductions occurred between the gizzard and duodenum.

HEMATOZOA IN SAGE GROUSE FROM COLORADO
Journal of Wildlife Diseases, 1977Blood films from 361 sage grouse ( Centrocercus urophasianus ) from North Park, Colorado, were examined for hematozoa. Parasites found were: Plasmodium pedioecetii , Haemoproteus canachites , Leucocytozoon bonasae , Trypanosoma avium , and microfilariae. The sage grouse represents a new host record for Plasmodium .

Weights of Colorado Sage Grouse
The Condor, 1978Sage Grouse ( Centrocercus urophasianus) are the largest North American grouse, both in body dimensions and weight. Their weight differs between sexes and varies strikingly among regions and seasons (Table 1). Weight has been used as a criterion for sex determination (June 1967). However, there is little systematic information on seasonal weight change.

Dispersion of displaying male sage grouse
Behavioral Ecology and Sociobiology, 1989The distribution of lek sizes was examined in each of three populations of sage grouse in eastern California. Peak seasonal lek sizes collected over a 35 year period were found to covary among the three sites indicating that some global environmental or demographic features modulated male attendance in any given year.

Lek Attendance of Male Sage Grouse
The Journal of Wildlife Management, 1984Le comptage des mâles sur les sites de reproduction est utilise pour estimer les tendances de la population en vue d'une bonne gestion de ce gibier (Centrocercus urophasianus).

Food Habits of Juvenile Sage Grouse
Journal of Range Management, 1968This study indicated the importance of forbs to sage grouse chicks. Only during the first week of a sage grouse's life did insects predominate in the diet. After that week, forbs became the most important food. Shrubs were taken in small amounts at first but progressively increased in importance as the chicks grew older.
