Daily nest survival rates (%) for Gunnison Sage-Grouse by incubation initiation (start week) for two populations in southwest Colorado, USA from 2005–2010.

<p>Estimates are from the model that includes year, start week, and nest age. 95% confidence intervals are shown as dashed lines and sample size by start week are shown on the x-axis.</p

Average vegetation measurements (with standard errors) for nests in the Gunnison Basin population (n = 177) and the San Miguel population (n = 20) of Gunnison Sage-Grouse in Colorado, USA.

<p>Data are separated by nests that succeeded (i.e., eggs hatched) and nests that failed from 2005–2010.</p
