New World Warblers (Parulidae)

Yellow-rumped Warbler (Dendroica coronata) - HBW 15, p. 748

French: Paruline à croupion jaune German: Kronwaldsänger Spanish: Reinita Coronada
Other common names: Myrtle Warbler (coronata and hooveri combined); Audubon's Warbler (auduboni); Black-fronted Warbler (nigrifrons); Goldman's Warbler (goldmani)

Taxonomy: Motacilla coronata Linnaeus, 1766, Philadelphia, Pennsylvania, USA.
Nominate race has hybridized with D. pinus; one record of hybridization (by race auduboni) with D. graciae. Races form two groups, formerly considered separate species, the N "Myrtle group" (nominate race and hooveri) and the W "Audubon's group" (auduboni, nigrifrons and goldmani). S sedentary races nigrifrons and goldmani are isolated from N migratory ones, and are now thought possibly to be sister-taxa that separated from N groups in the Pleistocene (N groups separating in the Holocene and still interbreeding in a narrow zone of..

Taxonomy: Motacilla coronata Linnaeus, 1766, Philadelphia, Pennsylvania, USA.
Nominate race has hybridized with D. pinus; one record of hybridization (by race auduboni) with D. graciae. Races form two groups, formerly considered separate species, the N "Myrtle group" (nominate race and hooveri) and the W "Audubon's group" (auduboni, nigrifrons and goldmani). S sedentary races nigrifrons and goldmani are isolated from N migratory ones, and are now thought possibly to be sister-taxa that separated from N groups in the Pleistocene (N groups separating in the Holocene and still interbreeding in a narrow zone of overlap); these two S resident taxa are, therefore, differentiated to the extent that they may represent two separate species, distinct from N migratory forms. Race hooveri weakly differentiated, and sometimes subsumed in nominate, from which differences largely clinal. Proposed race memorabilis (described from Boulder County, in Colorado), considered indistinguishable from auduboni. Five subspecies generally recognized.

Subspecies and Distribution:

  • hooveri McGregor, 1899 - breeds in Alaska and NW Canada (Yukon, C & S Northwest Territories and N British Columbia); migrates mainly to W USA and Middle America.
  • coronata ( Linnaeus, 1766) - breeds in S Canada (from NC Alberta E to Newfoundland and Nova Scotia) and NE USA (Minnesota and Wisconsin E to New England); migrates mainly to SE USA, E Middle America and Caribbean, also Bermuda.
  • auduboni ( J. K. Townsend, 1837) - breeds W North America from C British Columbia, W Alberta and Montana S in mountains to extreme NW Mexico (N Baja California) and S USA (W Texas); winters mainly in SW USA and Mexico (locally also S to Honduras).
