were
studied
in
North
Park,
Colorado,
during
the
winters
of
1973-74
and
1974-75.
Distribution
was
plotted
from
sightings
of
199
flocks
and

totaling
5,080
grouse.

sustained
winter
use
by
grouse
because
of
snow
depth,
steepness
of
slope,
and

turbance.
Nearly
80
percent
of
the
use
occurred
in
7
areas
comprising
less

7
percent

Sexes
segregated;
males

were
the
dominant
social
unit

tained
less

Flocks
containing

were
larger

| HEMATOZOA IN SAGE GROUSE FROM COLORADO | STABLER, RM | 1977 |
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 |

| Redescription of Eimeria centrocerci from Sage Grouse (Centrocercus urophasianus) | STABLER, RM | 1981 |
KeywordsNo keywords available AbstractEimeria centrocerci was found in the droppings from two of 153 sage grouse, Centrocercus urophasianus, from Moffat County, Colorado. Because Simon's (1939, 1940) figures are not clear and the description is ambiguous, a redescription of E. centrocerci from the sage grouse is presented.

| Sage Grouse Leks on Recently Disturbed Sites | CONNELLY, JW | 1981 |
KeywordsNo keywords available AbstractThree sage grouse (Centrocercus urophasianus) leks located on recently
disturbed areas within the Idaho National Engineering Laboratory Site are
described. A possible increase in the grouse population and lack of suitable
natural clearings in the general vicinity of these leks are suggested as
reasons for the bird's use of these areas. This species' acceptance of newly
cleared sites for display areas may have potential as a management tool. AuthorsCONNELLY, JW; ARTHUR, WJ; MARKHAM, OD Year Published1981 PublicationJournal of Range Management LocationsDOI10.2307/3898135 |
| 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.
