New World Warblers (Parulidae)

Orange-crowned Warbler (Vermivora celata) - HBW 15, p. 740

French: Paruline verdâtre German: Orangefleck-Waldsänger Spanish: Reinita Coroninaranja

Taxonomy: Sylvia celatus Say, 1823, "Engineer Cantonment, near Council Bluffs" = Omaha, Nebraska, USA.
Recent studies of mitochondrial DNA indicate that this species and V. peregrina, V. ruficapilla, V. virginiae, V. crissalis and V. luciae form a clade, separate from the two other current congeners, and should be placed in a separate genus, for which the name Leiothlypis has been proposed; Parula gutturalis and Parula superciliosa appear to be sister to this group. Four subspecies recognized.
