Description

The greater sage-grouse, a candidate species for listing under the Endangered Species Act (ESA) of 1973 has experienced population declines across its range in the sagebrush steppe ecosystems of western North America. Sage-grouse now occupy only 56% of their pre-settlement range, though they still occur in 11 western states and 2 Canadian provinces.

Spatial and temporal patterns of predation of simulated sage grouse nests at high and low nest densities: an experimental study

Keywords

No keywords available

Abstract

We examined patterns of predation on 252 simulated sage grouse (Centrocercus urophasianus) nests placed at two densities around six active leks in southeastern Wyoming, U.S.A. Predation intensity, as measured by the frequency of multiple-nest predation events, was significantly greater at high-density sites, implying enhanced prey capture (functional and (or) numerical response) by predators. Significant spatial aggregation of nest predation further implies enhanced prey capture by predators at high prey densities. Predation varied significantly among sites, but there were no significant first-order differences in predation between densities. Predation was also significantly affected by year-density and site-year-density interactions. Several factors, including nest cover, prey defense mechanisms, study site location, nest location, year, search methods of predators, number of predators, and random encounter may inhibit or confound density-dependent nest predation. Enhanced prey capture provides a mechanism for density-dependent population regulation.

Relationships between Vegetational Structure and Predation of Artificial Sage Grouse Nests

Keywords

artificial nest, Centrocercus urophasianus, habitat, nesting, Oregon, predation, sage grouse

Abstract

Because of high nest predation and long-term declines in sage grouse (Centrocercus urophasianus) productivity in Oregon, we assessed the effects of vegetational cover and height on predation of artificial sage grouse nests (n = 330). Artificial nest fate was positively associated with tall grass cover and medium-height shrub cover collectively (P = 0.01). No other vegetation, predator, temporal, or spatial variables explained any additional variation in the probability of predation. This study supports the hypothesis that greater amounts of tall grass and medium-height shrub cover at nest sites lower risk of nest predation for sage grouse. Management practices that increase cover and height of native grasses in sagebrush communities with medium-height shrubs are recommended to enhance sage grouse productivity.

Strutting sounds and strutting: Posturing of two Utah sage grouse populations

Keywords

No keywords available

Abstract

Sound and video tape recordings and still pictures were taken of two populations of strutting male sage grouse (Centrocercus urophasianus). The two populations studied were from the Strawberry Valley and Parker Mountains. Sixteen elements of sounds were identified in the strutting sequence. These elements were the same for both populations. Video tape and still picture analysis revealed that both populations were similar in posturing during the strutting sequence. We concluded that the Parker Mountains sage grouse population is suitable in terms of breeding display behavior to augment the Strawberry Valley population. Sexual compatibility would need to be determined in future studies.

Distribution and status of sage grouse in Colorado

Keywords

No keywords available

Abstract

Sage grouse (Centrocercus urophasianus) historically occurred in at least 23 and probably 27 counties within Colorado. Historic populations were largest in northern Colorado where sagebrush (Artemisia spp.) rangelands were most widespread. Currently, sage grouse occur in 15 counties in Colorado and are considered secure in only 5 counties. The long-term downward trend in sage grouse distribution and abundance in Colorado is related to loss of sagebrush-dominated rangelands and alteration and degradation of remaining sagebrush ecosystems. Management experiments are urgently needed to understand the importance of residual herbaceous cover to nest success and early brood survival. and to assess size and type of areas necessary to maintain viable populations of sage grouse.

A re-evaluation of hotspot settlement in lekking sage grouse

Keywords

No keywords available

Abstract

Recent analyses of avian leks have come to conflicting conclusions concerning the role of male settlement on female traffic hotspots. This issue was re-examined in the sage grouse, Centrocercus urophasianus, using data on pre-nesting movements of radiotagged females and the dispersion of lekking males collected during a 10-year field study. As expected with hotspot settlement, leks were preferentially located in areas through which females travelled between wintering and nesting ranges before mating. In addition, the distribution of males among leks was related proximately to variation in numbers of females visiting each lek during the mating period and ultimately to numbers that nested within a 2-km radius, within which nesting hens were preferentially attracted. The results show both that hotspot settlement can explain certain coarse scale features of male dispersion, and that female behaviour during different stages of the pre-nesting period may influence particular components of male dispersion to differing extents.

Availability of Foods of Sage Grouse Chicks following Prescribed Fire in Sagebrush-Bitterbrush

Keywords

Abstract

A study was conducted to determine the influence of prescribed fire on the availability of primary foods of sage grouse (Centrocercus urophasianus Bonaparte) chicks at Hart Mountain National Antelope Refuge, Lake County, Ore, from 1987 to 1989. Responses of certain primary foods and general food categories to fire were evaluated in sagebrush (Artemisia tridentata ssp. vaseyana Beetle)-bitterbrush (Purshia tridentata Pursh.) communities with a randomized block design established in stands where shrub cover exceeded 35%. Within blocks, habitat response was evaluated far 2 growing seasons on 4 plots used as controls, 3 plots burned in November 1987, and 4 plots burned in March 1988. Fall burning increased (P < 0.05) frequency of taxa in the dandelion tribe (Cichoriene). Other primary foods, including microsteris (Microsteris gracilis Hook.), desert-parsley (Lomatium spp. Raf.), and ground-dwelling beetles (Scarabaeidae, Tenebrionidae) were not influenced by burning. Spring and fall burning increased (P < 0.05) total forb cover and diversity, but decreased (P < 0.05) sagebrush cover. Prescribed fire may increase the supply of forbs available to sage grouse in montane sagebrush habitats used for brood-rearing where shrubs dominate stands at the expense of the herbaceous component.

Abstract

We investigated the short-term influence of fire on xeric sage grouse (Centrocercus urophasianus) brood habitat in southeastern Idaho from 1990-92. A prescribed fire in 1989 removed Wyoming big sagebrush (Artemisia tridentata wyomingensis Nutt.)/threetip sagebrush (A. tripartita Rydb.) canopy cover from approximately 57% of a 5,800-ha area, potentially influencing brood-rearing habitat. Although the fire created a mosaic of sagebrush areas interspersed with open areas having abundant grasses and forbs, the relative abundance of males, females, and broods on survey routes in burned and unburned habitat were similar, Cover of forbs important in sage grouse summer diets was similar in burned and unburned habitat, However, the abundance of Hymenoptera, an insect Order important in sage grouse diets, was significantly lower in burned habitat the second and third years postburn. Our research did not support the contention that fire may enhance sage grouse brood-rearing habitat.

Female choice in sage grouse: The roles of attraction and active comparisonGibson, RM1996

Female choice in sage grouse: The roles of attraction and active comparison

Keywords

No keywords available

Abstract

Previous studies of female choice in sage grouse Centrocercus urophasianus have implicated both the acoustic quality and repetition rate of the stereotyped strut display as putative cues for female choice. Stages in the choice process at which specific components of male courtship display influence female decisions were investigated using field observations of female pre-mating behavior. Females visited a subset of territorial males and then actively chose one of these as a mate. The order in which males were visited suggested that females searched until an acceptable mate was found, rather than employing a ''best-of-n'' tactic. Numbers of females visiting a male were related to differences in an acoustical component of display (inter-pop interval) whereas the probability that a visiting female mated was related to display rate (Table 3), indicating that initial attraction and active choice are influenced by different components of display. In addition, inter-pop interval and display rate tended to covary inversely (Fig. 1), suggesting that attraction and active choice may impose conflicting selection pressures on display performance.
