New World Warblers (Parulidae)

Colima Warbler (Vermivora crissalis) - HBW 15, p. 741

French: Paruline de Colima German: Colimawaldsänger Spanish: Reinita de Colima

Taxonomy: Helminthophila crissalis Salvin and Godman, 1889, Sierra Nevada de Colima, Mexico.
Recent studies of mitochondrial DNA indicate that this species and V. peregrina, V. celata, V. ruficapilla, V. virginiae 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. Present species sometimes included in the superspecies formed by V. ruficapilla and V. virginiae, and the three have been considered conspecific, although this trea.. View all taxonomy...

Taxonomy: Helminthophila crissalis Salvin and Godman, 1889, Sierra Nevada de Colima, Mexico.
Recent studies of mitochondrial DNA indicate that this species and V. peregrina, V. celata, V. ruficapilla, V. virginiae 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. Present species sometimes included in the superspecies formed by V. ruficapilla and V. virginiae, and the three have been considered conspecific, although this treatment not generally accepted. Some recent authors have suggested a close relationship with V. celata, this based on similarities in size, shape, song and habitat. Monotypic.

Distribution: Breeds in extreme S USA (Chisos Mts, in extreme SW Texas) and mountains of NE Mexico (Coahuila, Nuevo León, NE Zacatecas, N San Luis Potosí and SW Tamaulipas). Migrates to non-breeding grounds on Pacific slope of W Mexico from Sinaloa to Guerrero (mainly Jalisco and Michoacán), also in small numbers in Morelos and Distrito Federal.
