From mid-March through mid-August 1998-2000, we studied greater sage-grouse Centrocercus urophasianus nesting habitat in northeastern California, USA. We located nest sites of 45 radio-marked hens, which had an average nest success of 40.2%. The radio-marked grouse used low sagebrush Artemisia arbuscula cover type less than expected; big sagebrush A. tridentata wyomingensis and mixed shrub cover types were used in proportion to their availability. Grouse used sites with habitat characteristics similar to random sites for nesting. However, successful nests differed from unsuccessful nests in several respects. Mean distance between nest and lek was greater for successful nests (x̄ = 3,588 m, SE = 811 m, N = 20) than for unsuccessful nests (x̄ = 1,964 m, SE = 386 m, N = 20). Rock cover was greater at successful nests (x̄ = 27.7%, SE = 4.6%) than at unsuccessful nests (x̄ = 14.49%, SE = 3.04%). Total shrub height was greater at successful nests (x̄ = 65.5 cm, SE = 4.7) than at unsuccessful nests (x̄ = 492 cm, SE = 1.7), The height of visual obstruction was greater at successful nests (x̄ = 40.2 cm, SE = 2.6) than at unsuccessful nests (x̄ = 32.5 cm, SE = 2.0). Our results suggest that sage-grouse use more diverse vegetation than previously reported, and we conclude that either this represents a natural behaviour for sage-grouse in this area, or we observed a selection response to a landscape altered by human activity.
