Virginia's Warbler Identification Guide

Key Field Marks

• Size & shape: A small, active warbler with a fairly plain gray body and no wing bars, typical of the Leiothlypis (formerly Vermivora) genus.
• Plumage: Gray head, back, and wings; a bright yellow rump and yellow patch on the breast/upper belly; yellow undertail coverts.
• Face: A bold, complete white eye-ring on an otherwise plain gray face is a key identifying feature.
• Behavior: Forages actively low in scrub and understory, often flicking its tail while gleaning insects from foliage.

Separating Virginia's Warbler from Similar Species

• Nashville Warbler: Shows a much more extensive yellow underside (yellow extends across the whole breast and belly, not just a patch), a greener back, and overlapping but generally more northerly/different breeding range.
• Colima Warbler: Larger and more richly colored with buffier undertail coverts and lacks the strong, contrasting yellow breast patch of Virginia's Warbler; restricted to the Chisos Mountains of Texas and adjacent Mexico.
• Lucy's Warbler: Grayer overall with a rufous (not yellow) rump and crown patch, and no yellow breast patch, favoring lower desert riparian habitat rather than montane scrub.

Where & When to See One

Breeds in dry montane scrub, pinyon-juniper woodland, and oak or chaparral thickets in the mountains of the interior Southwest — Arizona, New Mexico, Colorado, Utah, and parts of surrounding states — as well as adjacent northern Mexico. A long-distance migrant, wintering primarily in western Mexico. Look for it in brushy mountain slopes during the breeding season, working low through scrub rather than high in the canopy.

Voice

A bright, trilled song similar in style to other Leiothlypis warblers, often a rapid series of similar notes with a slight change in pitch or emphasis partway through; the call note is a sharp, dry "chip."
