Abstract:

“I investigated the habitat use and movements of sympatric female sage grouse (Centrocercus urophasianus) and Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) during the breeding, nesting, and brood-rearing periods in the Curlew Valley region of southeastern Idaho. During March and April of 1988 through 1991, I captured 69 female sage and 75 female Columbian sharp-tailed grouse on or near strutting or dancing grounds, respectively. I radio-marked 85 (37 sage grouse, 48 Columbian sharp-tailed grouse) female[s…]. I also experimentally tested predictions of the Male Avoidance (M-A) and Sentinel Decoy (S-D) theories of lek evolution through the construction of 551 artificial Columbian sharp-tailed grouse nests during April through June of 1990 (262 nests) and 1991 (289 nests). The nests were constructed and checked around 7 different active Columbian sharp-tailed grouse dancing grounds at 6 sequentially increasing distances (0.25, 0.50, 0.75, 1.00, 1.50, 2.00 km) from the center of the lek. The artificial nests were checked a[t] 1, 3, 6, and 9 days following construction to determine fate.”
