Grace's Warbler (Dendroica graciae), Roger Road WRF, Tucson, Pima County

This Grace's Warbler was discovered by Mark Stevenson on 09 September 2009 in a pine tree at elevation 2254 ft at Roger Road WRF. It was photographed the same day by Andrew Core.

Grace's Warbler is one of a suite of highland breeding species that are only very rarely detected in the lowlands during migration.  Other species with a similar pattern include Cordilleran Flycatcher, Red-faced Warbler and Painted Redstart.  Monson & Philips (1981) list only 7 lowland records through 1980 of Grace's Warbler.

Yellow-throated Warbler is the only likely confusion species.  The broad yellow eyeline and gray face blending with the gray back separate Grace's from Yellow-throated Warbler which has a different face pattern.
