A fairly common summer resident of mixed conifer forests on the Kaibab Plateau and an uncommon and local summer resident of ponderosa pine forests elsewhere in the region. It is a fairly common spring and common fall migrant throughout the region, with spring migrants occurring until at least 17 May, and fall migrants appearing as early as 22 Jul. House Wren may be an uncommon winter resident along the Colorado River, where it was previously unknown. A series of winter river trips in 1998 and 1999 produced seven records, all below RM 200 (LaRue et al. 2001). Conditions may vary among subspecies. Data source: Gatlin, BP. 2011.
