Vireos (Vireonidae)

Hutton's Vireo (Vireo huttoni) - HBW 15, p. 427

French: Viréo de Hutton German: Huttonvireo Spanish: Vireo de Hutton

Taxonomy: Vireo huttoni Cassin, 1851, Monterey, California, USA.
May be most closely related to V. carmioli; more study needed. Very wide divergence between coastal nominate race and interior stephensi, indicating effective genetic separation of sufficiently long standing to raise the question of distinction at species level, further study required. Proposed race insularis, described from Victoria, on Vancouver I (British Columbia), in Canada, is synonymized with obscurus. Eleven subspecies recognized.
