Wildlife habitats in managed rangelands - the Great Basin of southeastern Oregon. Sage grouse.KeywordsNo keywords available AbstractDecreases in sage grouse followed the decrease in sagebrush. Other factors, such as unfavorable weather conditions at hatching time and increased predation, hunting, and disease have each been important at various times in localized areas but are probably not the most important factors in the overall downward trend.

| METHODS FOR TRAPPING SAGE GROUSE CENTROCERCUS-UROPHASIANUS IN COLORADO USA | GIESEN K M | 1982 |
METHODS FOR TRAPPING SAGE GROUSE CENTROCERCUS-UROPHASIANUS IN COLORADO USAKeywordsNo keywords available AbstractDuring 1963-1980 at least 6231 sage grouse (C. urophasianus) (5147 adults, 1084 juveniles) were captured and banded in Colorado. Most (5752) were banded since 1973. Four trapping methods were evaluated for capture efficiency (spotlighting, drive traps, stationary cannon nets and vehicle-mounted cannon nets) between 1977 and 1980 during which 1955 grouse were captured. Spotlighting resulted in most captures (1326; 67.8%) followed by drive trapping (347; 17.7%), vehicle-mounted cannon nets (221; 11.3%) and stationary cannon nets (61; 3.1%). Spotlighting was least selective for age or sex of birds trapped except when trapping on leks. Drive trapping and both methods of cannon-netting were selective for juveniles. Trapping mortality was < 1.0% for all trapping methods with injuries most common in drive trapping and cannon-netting.

| VOLUNTEER COLLECTION STATION USE FOR OBTAINING GROUSE WING SAMPLES | HOFFMAN R W | 1981 |
VOLUNTEER COLLECTION STATION USE FOR OBTAINING GROUSE WING SAMPLESKeywordsNo keywords available AbstractVolunteer wing collection stations were tested in Middle Park, Colorado [USA] during 1975-1979 as an alternative means of inexpensively increasing collected grouse wing samples. Of 3791 blue grouse (Dendragapus obscurus) and sage grouse (Centrocercus urophasianus) wings collected, 3213 (84.7%) were deposited in wing stations. Less time, manpower and expense were required to operate volunteer wing stations for the entire season than for check stations on opening weekend. Besides the basic population data derived from wing analyses, other important management information obtained included identification of major harvest areas, evaluation of hunter success and assessment of harvest distribution over time.

HEMATOZOA IN SAGE GROUSE FROM COLORADOKeywordsNo keywords available AbstractBlood films from 361 sage grouse (Ccnlroccrcus urophasianus) from North
Park, Colorado, were examined for hematozoa. Parasites found were: Plasmodium
pedioecetii, Haemoproteus canacbzitcs, Leucocytozoon bonasae, Trypanosoma avium,
and microfilariae. The sage grouse represents a new host record for Plasmodium.
Prevalence of parasitism was not age or sex related, with no significant (P > 0.05)
differences between age or sex class. Parasite burdens increased significantly
(P< 0.05) from January through May. As these burdens rose prior to the emergence
of potential vectors, probably it was a true relapse associated with the resumption
of the hosts? sexual activity. AuthorsSTABLER, RM; BRAUN, CE; BECK, TDI Year Published1977 PublicationJournal of Wildlife Diseases Locations |
