New World Warblers (Parulidae)
MacGillivray's Warbler (Oporornis tolmiei) - HBW 15, p. 769
French: Paruline des buissons
German: Dickichtwaldsänger
Spanish: Reinita de Tolmie
Taxonomy: Sylvia Tolmiei J. K. Townsend, 1839, Columbia River = Fort Vancouver, Clarke County, Washington, USA.
Genus sometimes subsumed in Geothlypis. Forms a species pair with O. philadelphia, the two probably constituting a superspecies; ranges overlap in W Canada (Peace Region of British Columbia); claimed hybrids from this zone have been considered variants of O. philadelphia with white eye-crescents (such variants occur throughout that species' range), but recent analysis combining molecular and morphological data sets confirms numerous hybrid individuals with mixed characters, including 18 of 50 birds genotyped (36%) showing both western and eastern alleles. Proposed race

Proposed race austinsmithi (described from near Chico, in Montana) treated as a synonym of nominate, and intermedia (described from Okanagan, in S British Columbia) synonymized with monticola. Two subspecies currently recognized.
Subspecies and Distribution:
- tolmiei ( J. K. Townsend, 1839) - breeds Pacific coastal region and Cascades from extreme SE Alaska and S Yukon S in W USA to C California; migrates to region from Mexico S to Guatemala, in smaller numbers to W Panama.
- monticola A. R. Phillips, 1947 - breeds from SW Canada (E British Columbia and SW Saskatchewan) S in Rocky Mts and adjacent areas to Arizona and New Mexico, with isolated population in Black Hills of South Dakota-NE Wyoming; migrates to Mexico and Guatemala.
