Visibility bias for sage‐grouse lek counts
Wildlife Society Bulletin, 2017 Declining populations of greater sage‐grouse (Centrocercus urophasianus; hereafter, sage‐grouse) necessitate accurate estimates of population trends. The most widespread approach to monitoring sage‐grouse populations involves counting males attending ...

Greater sage‐grouse male lek counts relative to a wind energy development
Wildlife Society Bulletin, 2017 Wind energy development is an emerging source of anthropogenic disturbance that could affect greater sage‐grouse (Centrocercus urophasianus; sage‐grouse) populations.

Improving population size estimation at western capercaillie leks: lek counts versus genetic methods
Journal of Avian BiologyThe western capercaillie Tetrao urogallus, hereafter capercaillie, is the largest galliform bird present in the boreal and montane forests of the Western Palearctic.

PLoS ONE, 2019 Researchers and managers are often interested in monitoring the underlying state of a population (e.g., abundance), yet error in the observation process might mask underlying changes due to imperfect detection and availability for sampling.

Volunteer Observer Bias and Sharp-Tailed Grouse Lek Counts in the Upper Midwest
Journal of Fish and Wildlife Management, 2018 Abstract For most species of prairie grouse Tympanuchus spp. standardized monitoring protocols do not exist across adjoining jurisdictions. For instance, researchers monitor relatively small and disjunct populations of prairie sharp-tailed grouse Tympanuchus phasisanellus campestris in Michigan, Wisconsin, and Minnesota using ...

Can Reliable Sage-Grouse Lek Counts Be Obtained Using Aerial Infrared Technology?
Journal of Fish and Wildlife Management, 2013 Abstract More effective methods for counting greater sage-grouse (Centrocercus urophasianus) are needed to better assess population trends through enumeration or location of new leks. We describe an aerial infrared technique for conducting sage-grouse lek counts and compare this method with conventional ground-based lek count methods.

Evaluating the Potential of Aerial Infrared as a Lek Count Method for Prairie Grouse
Journal of Fish and Wildlife Management, 2015 Abstract Wildlife biologists use counts of birds attending traditional breeding grounds (i.e., leks) to develop indices of population trends in several grouse species. Standardized lek counts for sage-grouse Centrocercus spp. provide information about population trends by allowing comparison of counts across their range.

Trends in greater sage‐grouse lek counts relative to existing wind energy development in Wyoming
Wildlife Society BulletinRapid increases in wind energy development globally highlight the need to evaluate how electricity generation may impact wildlife. The greater sage‐grouse (Centrocercus urophasianus; hereafter, sage‐grouse) has experienced range‐wide population declines,

Combined effects of energy development and disease on greater sage-grouse. [PDF]
PLoS ONE, 2013 Species of conservation concern are increasingly threatened by multiple, anthropogenic stressors which are outside their evolutionary experience. Greater sage-grouse are highly susceptible to the impacts of two such stressors: oil and gas (energy ...

Spatial heterogeneity in response of male greater sage-grouse lek attendance to energy development. [PDF]
PLoS ONE, 2014 Landscape modification due to rapidly expanding energy development, in particular oil and gas, in the westernUSA, have prompted concerns over how such developments may impact wildlife.
