A replicated study in Strawberry Valley, Utah, USA (Baxter et al. 2008) examined the survival of 141 female greater sage-grouse Centrocercus urophasianus introduced into a resident population of 150 during the breeding seasons of 2003-2005. Survival rate was 60% in 2003, with all surviving birds integrated into resident sage-grouse flocks. Across all years, 36% of newly translocated birds, and 73% of females in their second year after translocation attempted nesting. The source populations were tested for presence of infections (in particular Salmonella pullorum) prior to translocation. Individuals were captured shortly after sunset, packed in cardboard boxes (30.5cm x 22.9cm x 30.5cm) for 10hrs transit, and equipped with radio-transmitters before release the following morning. The release site was close to an active lekking site, with sagebrush available for immediate cover.
