    <p>Nest success estimates by year (2005–2010) and population (Gunnison Basin and San Miguel) for Gunnison Sage-Grouse in Colorado, USA, with 95% confidence intervals. The estimates are based on model averaging and sample sizes are by year.</p

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