Table 2.
Mean values of a resource selection function for greater sage-grouse (RSF) and survival probability function for greater sage-grouse (SPF) at nests of three species of sagebrush-associated songbirds nesting in central Wyoming, USA, 2012 – 2013. The RSF is a relative measure of nest-site preference, and the SPF is a measure of the probability of a nest surviving to produce young.
