Figures 252, 253 (above, below). Two views of a first-fall Blue-headed Vireo at Southeast Farallon Island on 21 September 2001. Bright Cassin’s Vireos can look very similar, and some birds may not be safely distinguishable. Useful marks evident in these photos include the crisp division between gray-blue head and immaculate white throat, bold whitish fringes to the outer rectrices, well-defined white tertial edges, and extensively yellow sides, flanks, and undertail coverts (2002-014; Kristie N. Nelson).

Figure 254. The CBRC encourages the use of cameras to document review-list birds, but field art is always appreciated by Committee members charged with reviewing hundreds of records each year. This sketch of a Blue-headed Vireo, made on 4 October 2003 at Pt. Loma in San Diego County, shows most of the relevant marks and supports the record with flair (2003-127; Susan E. Smith).

Blue-headed Vireo

BLUE-HEADED VIREO Vireo solitarius (Wilson, 1810)

Accepted: 35 (55%)

Treated in Appendix H: yes

Not accepted: 29

CBRC review: all records1

Not submitted/reviewed: 77

Large color images: see Figures

With the recognition of three species in the Solitary Vireo complex (Johnson 1995, AOU 1997), the Committee was compelled to review records of the Blue-headed Vireo, a rare vagrant from the East. This species breeds from southeastern Yukon and the southern Northwest Territories east to Newfoundland, and from Minnesota east to New England and southward through the Appalachian Mts. to northeastern Alabama. The wintering grounds extend from the Southeast and Texas south through eastern Mexico to Costa Rica (casually to Panama), and some birds winter in Cuba. The species migrates regularly through the East and casually through the West. Washington claims two early fall vagrants: 6 September 1995 (coastal) and 28 August 2000 (inland). Oregon adds a coastal bird on 4 October 1980 and an inland bird photographed on 25 May 2003. Individuals were photographed in northwestern Baja California Sur on 1 October 2003 (NAB 58:148, 172) and 5 October 2004 (NAB 59:154) and in northeastern Baja California 8–12 March 2006 (NAB 60:289, 315).

California’s first Blue-headed Vireo was a first-fall female (identification confirmed by Allan R. Phillips) collected on 30 September 1973 on San Nicolas Island, Ventura County. This species is a generally late fall migrant in the East, and it winters in the Southeast, life-history traits that are reflected in the species’ incipient patterns of occurrence in California: 31 accepted records are of fall vagrants (9 September–28 November, with only three multi-day records); three are from winter, north to Ventura County; and one is of a singing spring vagrant (13 May 2000 at Huntington Beach, Orange County). See also Appendix H. At Southeast Farallon Island, where most records have not been reviewed by the CBRC, the mean date for 31 fall records is 30 September (Richardson et al. 2003).

Criteria for field identification have only recently been disseminated (see Heindel 1996, Pyle 1997b), and differences between some Blue-headed Vireos and bright Cassin’s Vireos can be subtle. This high potential for confusion may lead either to over- or under-reporting of Blue-headed Vireos in California, and it certainly leads many Committee members to demand impeccable details when considering these records. Most Cassin’s Vireos move through California between late August and October, whereas the earliest Blue-headeds normally do not appear until mid September. The Washington records listed previously are exceptionally early, and both are single-observer sight records. The CBRC is unlikely to accept similarly early reports of this species without diagnostic photos or excruciatingly detailed written descriptions. To mention but one of many intricacies inherent to the Solitary Vireo complex, Cassin’s Vireos resident in the Cape District of Baja California Sur (V. c. lucasanus) resemble Blue-headed Vireos, and their vocal repertoires reportedly include songs typical of both Cassin’s and Blue-headed Vireos (NAB 57:261).

Many Blue-headed Vireo reports have not been submitted (and others have not been accepted) because adequate details do not exist. Still, the CBRC continues to request submissions of any documentation that could serve to support published reports of this taxon.
