Blue-headed Vireo (Vireo solitarius)

The Blue-headed Vireo, the Cassin's Vireo, and the Plumbeous Vireo were all considered one species, the Solitary Vireo, until the 1990's. The Blue-headed is the eastern component of the three, migrating throughout the eastern half of the United States to it's summer destinations in the northeastern U.S. and Canada. In South Dakota, they're the one of the three species that is found in the eastern half of the state as they migrate through in both the spring and the fall. The Plumbeous Vireo (a grayish, less colorful species) is found in the Black Hills of South Dakota.

Habitat

Blue-headed Vireos use open mixed forests during the summer breeding season. They are the only species of vireo in most of North America that will nest and frequently use conifer/evergreen forests. They area also found in open forests and woodlands during migration and in winter.

Diet

Primarily feeds on insects and spiders. They will also consume fruits and berries, especially during the winter months.

Behavior

Primarily forages in the upper portion of trees. They will sometimes observe from a perch and flycatch, flying out to catch passing insects, or clamber along major branches and tree trunks in search of prey.

Breeding

Non-breeder in South Dakota. In breeding range, the nest is a cup made of grasses, weeds, roots, and moss, lined with downy plant material or animal hair. The female lays 3 to 5 eggs, which are incubated by both parents. Upon hatching, both parents tend to the young, who leave the nest after about 2 weeks.

Song

Melodic "vireo-like" phrases, slower in pace than other vireo species and with distinct pauses in between each phrase. Blue-headed Vireos also have a chattering, scolding call given in alarm or in defense of a nest site.

Migration

Summers in central through southeastern Canada, the Great Lakes Region, New England, and southward through the Appalachians. Winters near the Gulf and Atlantic coasts in the Southeastern United States, as well as Mexico and Central America.

Similar Species

Vireo species can be confusing and Blue-headed Vireo could potentially be confused with the following species:

Cassin's Vireo - One of the species formerly considered the same species as Blue-headed Vireo, Cassin's Vireo are found in areas nearer the West Coast of North America, and aren't an identification problem in South Dakota. In appearance, the two species are very close, but Cassin's Vireo have less yellowish color on their flanks, and a lesser contrast between the gray head and greenish back than a Blue-headed Vireo.
Plumbeous Vireo - Plumbeous Vireo were also once considered the same species, and they are found in the Black Hills. Sightings of Blue-headed Vireo in the Black Hills though are extremely rare, however. In appearance, Plumbeous Vireo are less colorful than Blue-headed Vireo, with an overall gray appearance.
Bell's Vireo - A species found in South Dakota that could cross paths with a Blue-headed Vireo, Bell's Vireo lack the strong "spectacles" look of the Blue-headed Vireo and tend to show less yellowish/greenish tones on the flanks and back. The wingbars on a Bell's Vireo are also paler than those on a Blue-headed Vireo.
Warbling Vireo - Another species of vireo found in South Dakota, they have a pale eye-stripe that could be confused with the "spectacles" look of a Blue-headed Vireo, but it extends behind the eye. Warbling Vireos lack the wingbars of a Blue-headed Vireo, and tend to have less of a yellowish/greenish wash on the flanks and back.

Conservation Status

They are quite frequent hosts to cowbird parasitism, and habitat fragmentation makes them more susceptible. However, systematic surveys show substantial population increases over recent decades. They are found across a broad geographic area, and are common in parts of that range. The IUCN lists the Blue-headed Vireo as a species of "Least Concern."
