Red-eyed Vireo © sdakotabirds.com

Vagrant to Greenland, Iceland, Ireland, Jamaica, Malta, Morocco, Netherlands, Poland, United Kingdom, Virgin Islands (U.S.).

Probably forms a superspecies with Noronha Vireo (Vireo gracilirostris), Yellow-green Vireo (Vireo flavoviridis), Black-whiskered Vireo (Vireo altiloquus) and Yucatan Vireo (Vireo magister). Often treated as conspecific with Noronha Vireo (Vireo gracilirostris), but latter appears distinct. Sometimes regarded as conspecific with Yellow-green Vireo (Vireo flavoviridis), but biochemical studies coupled with morphological and vocal differences strongly indicate that the two are distinct species. Neotropical subspecies treated by some authors as representing a distinct species, under name of "Vireo chivi", although this apparently diverged from nominate only c. 370,000 years ago (whereas Yellow-green Vireo (Vireo flavoviridis) and present species diverged from each other c. 4-6 million years ago). It is hypothesized that the "chivi group" of subspecies arose from wintering individuals of nominate subspecies from North America that failed to migrate back northern in spring, and in a situation where migration is largely unnecessary, and consequent gene-pool mixing of different populations is reduced, further subspeciation of Neotropical populations is likely. Additional work required on some resident South American subspecies, which appear to have distinct vocalizations, before the matter can be resolved. One report of hybridization with Philadelphia Vireo (Vireo philadelphicus) in south-eastern Canada (Quebec).

The following 10 subspecies are recognised:

• olivaceus (Linnaeus, 1766)   -  Breeds Canada (except north-western and north) and north-west, central and eastern USA; migrates to northern South America.
• caucae (Chapman, 1912)   -  Western Colombia (Pacific coast at Juradó, western slope of western Andes, and valleys of upper R Patía and upper R Cauca).
• vividior Hellmayr and Seilern, 1913   -  Colombia (south to Meta), Venezuela, the Guianas, extreme northern Brazil, and Trinidad.
• tobagensis Hellmayr, 1935   -  Tobago.
• griseobarbatus (Berlepsch and Taczanowski, 1884)   -  Western Ecuador and north-western Peru.
• pectoralis J. T. Zimmer, 1941   -  Northern Peru (middle Marañón Valley).
• solimoensis Todd, 1931   -  Eastern Ecuador, north-eastern Peru, and western Brazil (east to lower R Negro, south to upper R Juruá and R Purús).
• chivi (Vieillot, 1817)   -  Central Peru, west-central Brazil, eastern Bolivia, western Paraguay, and north-eastern Argentina (south to San Luis, Córdoba, Santa Fe and northern Buenos Aires). Non-breeding eastern Colombia, southern Venezuela and north-central Brazil (south of R Amazon).
• agilis (M. H. C. Lichtenstein, 1823)   -  Eastern Brazil (eastern from near Faro on northern bank of R Amazon and, on southern bank, from R Madeira) south to Rio de Janeiro.
• diversus J. T. Zimmer, 1941   -  Eastern Paraguay, south-eastern Brazil and Uruguay.
