Nebraska’s first Grace’s Warbler was found at the headquarters complex at Crescent Lake NWR by Cory Gregory. This species occurs north and east to south-central Colorado, where the range may be expanding northward (Stacier and Guzy 2002). The closest Colorado record is on the plains in Washington Co, Colorado 2 Jun 2006 (eBird.org, accessed May 2018), and there are a few additional records along the northeastern Colorado foothills, but none for Kansas (Thompson et al 2011).
