A fairly common summer resident of mixed conifer forests of the Kaibab Plateau. Brown et al. (1985) considered this species uncommon and Red-naped Sapsucker fairly common on the Kaibab, but Arizona Breeding Bird Atlas (AZBBA) surveys found the opposite to be true (Latta and Corman 2005). The AZBBA also found Williamson’s Sapsucker to be a rare and local summer resident in ponderosa-oak forests on Mounts Trumbull and Logan. Williamson’s Sapsucker is seen in wooded areas on and below the South Rim as an uncommon spring and fall migrant and casual winter resident. The only true winter records are of a female at Tusayan Museum 1 Feb 2006 (Brian P. Gatlin) and one at Grand Canyon Village on 6 Feb 1949 (Harold Bryant). Spring migrants are present from 24 Feb to 12 May, while fall migrants may begin to appear as early as 1 Aug and continue through 16 Nov. There are three fall records from the Colorado River (4 Sept to 23 Sept). Data source: Gatlin, BP. 2011. Annotated Checklist of the Birds of the Grand Canyon Region. 3rd edition.
