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.

Abstract

Sage Grouse (Centrocercus urophasianus) brood-habitat use was examined during 1992 and 1993 at the Yakima Training Center in Yakima and Kittitas counties, Washington. During the 2 yr we followed 38 broods, of which 12 persisted to 1 August ((x) over bar = approximately 1.5 chicks/brood). Food forb cover was greater at all brood locations than at random locations. Hens with broods in big sagebrush/bunchgrass habitat (Artemisia tridentata/Agropyron spicatum) selected for greater food forb cover, total forb cover, and lower shrub heights; broods in altered big sagebrush/bunchgrass habitats selected greater tall grass cover and vertical cover height; broods in grassland showed no preference for any measured vegetation characteristics. During the early rearing period (post-hatching-6 wk) each year, broods selected sagebrush/bunchgrass. Broods in 1993 made greater use of grasslands than in 1992 and selected grassland during the late brood-rearing period (7-12 wk). Broods selected for sagebrush/bunchgrass during midday, but 52% of brood locations in the afternoon were in grassland. Tall grass cover was greater at morning (0500-1000 h) and afternoon (1501-2000 h) brood locations than at midday (1001-1500 h) and random locations. Midday brood locations had greater shrub cover and height than morning and afternoon locations. Selection of habitat components was similar to the results of other studies, but habitat conditions coupled with a possible lack of alternate brood-rearing cover types resulted in low survival of chicks.

Abstract

We compared summer movement patterns of female Sage Grouse (Centrocercus urophasianus) in southeastern Idaho before (1987-1989) and after (1990-1992) a prescribed fire which removed vegetation cover, primarily Wyoming big sagebrush (Artemisia tridentata wyomingensis), from approximately 57% of a 5800 ha area. Grouse moved 1-69 km ((x) over bar = 17.8 +/- 2.0 km [SE]; N = 81) from breeding and nesting areas to summer ranges, predominantly in northwest or southwest directions during the 6-year period. There was no difference in timing, distance, or direction moved between birds captured in burned and unburned habitats. The data provided further evidence of traditional migration routes for Sage Grouse breeding and nesting in the Big Desert.

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.

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

Keywords

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

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.

Abstract

We translocated 196 Sage Grouse (Centrocercus urophasianus) into Sawtooth Valley, Idaho, during March-April 1986-87 to augment a small resident population. Forty-four grouse equipped with radio transmitters were monitored through spring and summer. Nest sites (n = 6) had greater (P = .032) horizontal cover than did independent random plots (n = 7). During summer, grouse used sites (n = 50) with taller live and dead shrub heights, greater shrub canopy cover, and more ground litter (P < .009) than were found on dependent random plots (n = 50) 50-300 m from use sites. Distance to edge and mountain big sagebrush (Artemisia tridentata vaseyana) density best separated use sites from independent random plots in logistic regression analysis and correctly classified 64% of the use sites and 78% of the independent random plots. Sage Grouse used sites that had narrower frequency distributions for many variables than did independently plots (P < .04), suggesting selection for uniform habitat.

THE INFLUENCE OF SEASON, TEMPERATURE, AND ABSORPTIVE STATE ON SAGE GROUSE METABOLISM

Abstract

We used indirect respiration calorimetry to measure the metabolism of six adult sage grouse (Centrocercus urophasianus) during winter, spring, and summer. During winter the metabolic rate of fed birds was higher (P < 0.05) than that of fasted birds. The standard metabolic rate (SMR) of females (0.692 mL O-2.g(-1).h(-1)) was higher than of males (0.583 mL O-2.g(-1).h(-1)) in winter; in both sexes SMR was higher in winter than in summer. Females' SMR was lower (P = 0.0001) in spring than in winter. Lower critical temperatures of both males and females were substantially lower in winter (-0.6 degrees C, -4.8 degrees C) than in summer (14.9 degrees C, 14.8 degrees C). Although seasonally elevated, the SMR of sage grouse in winter is low in comparison with that of other galliforms with northern distributions. Thermoregulation during a winter night at -10 degrees C would result in minimal (<5%) expenditure of endogenous reserves by either sex. Thermoregulation and SMR in winter are more energetically costly to female sage grouse than to males, and may necessitate increased behavioral thermoregulation by females. Seasonal change in SMR differs between the sexes, and is probably influenced by the energetic demands of the breeding season.

BROOD HABITAT USE BY SAGE GROUSE IN OREGON

Keywords

No keywords available

Abstract

Habitat use by Sage Grouse (Centrocercus urophasianus) hens with broods was examined at Jackass Creek and Hart Mountain, Oregon, from 1989 through 1991. Sage Grouse hens initially selected low sagebrush (Artemisia spp.) cover types during early brood-rearing, big sagebrush cover types later in the brood-rearing period, and ultimately concentrated use in and near lakebeds and meadows. Areas used by Sage Grouse broods typically had greater forb frequency than did random sites. Hens at Jackass Creek selected sites with forb cover similar to that generally available to broods at Hart Mountain, but home ranges were larger at Jackass Creek because of lower availability of suitable brood-rearing habitat. Differences in habitat use by broods on the two areas were reflected in dietary differences; at Hart Mountain, chicks primarily ate forbs and insects, whereas at Jackass Creek most of the diet was sagebrush. Larger home ranges, differences in diets, and differences in availability of forb-rich habitats possibly were related to differences in abundance and productivity between areas.

PREDATION OF ARTIFICIAL SAGE GROUSE NESTS IN TREATED AND UNTREATED SAGEBRUSH

Abstract

We measured predation on 120 artificial Sage Grouse (Centrarcus urophasianus) nests in montane sagebrush grassland in northern Utah. We examined nests in areas that had been chained and seeded 25 years previously (treated areas) and in areas that were untreated. Predation rates of artificial nests were higher in areas of untreated sagebrush, even though these areas had greater sagebrush cover, taller shrubs, and greater horizontal plant cover. These results differ from those previously hypothesized for treated sagebrush habitat and may reflect a greater abundance of other potential prey species, especially lagomorphs, in untreated areas that attracted greater densities of predators. In addition, over 80% of nests were depredated by mammals, which hunt using olfaction and are less likely than avian predators to be affected by nest cover. We conclude that, after treated sagebrush has recovered to some degree, predation rates of Sage Grouse nests may be lower in treated sagebrush. Consequently, factors other than nest predation (e.g., winter food, thermal cover, insects, perennial forb abundance) may be more important reasons for preserving mature sagebrush stands for Sage Grouse.
