A rare but regular summer visitor to ponderosa pine and mixed conifer forests on the North Rim and a rare fall migrant on the South Rim (Brown et al. 1987). Recent records are scarce, and at present the species is probably not more than a casual summer visitor. One was at Big Springs on the Kaibab Plateau from 9-22 Jun 1996 (Troy Corman), another was on the Kaibab Plateau on 29 Jun 2008, one was at the aspen grove on the South Rim on 9 Jul 2008, and another or the same was less than half a mile away at Hearst Tanks on 15 Aug 2008 (both Brian P. Gatlin). There remains no evidence for breeding. Data source: Gatlin, BP. 2011. Annotated Checklist of the Birds of the Grand Canyon Region. 3rd edition.

First seen in the region in 1975, by 1985 Red-faced Warbler was a rare but regular summer visitor to ponderosa pine and mixed conifer forests on the North Rim and a rare fall migrant on the South Rim (Brown et al. 1987)
