Monoterpenoid content of sage grouse ingesta

Journal of Chemical Ecology, 1989
We 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, 1977
Blood 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, 1978
Sage 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, 1989
Summary. The degree to which male sage grouse select lek sites and females select nesting sites to maximize proximity to the other sex was examined by contrasting male dispersions with the dispersions and movements of females in the months preceeding incubation.

Renesting by Sage Grouse in Southeastern Idaho

The Condor, 1993
Renesting in Tetraonidae has been investigated in a number of studies (e.g., Patterson 1952, Zwickel and Lance 1965, Giesen and Braun 1979, Parker 1981, Bergerud 1988, Bergerud and Gratson 1988). Unfortunately, information on renesting by Sage Grouse (Centrocercus urophasianus) is limited and highly variable.

Food Habits of Juvenile Sage Grouse

Journal of Range Management, 1968
This 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.
