"Bluish-gray to gray head, olive to grayish-olive back and rump ... bright white below with bright yellow sides ... Bright white spectacles and throat contrast strongly with dark gray face ... "(The Stokes Field Guide to the Birds of North Amrica, p. 491)

Tveten, who calls this the Solitary Vireo, (307) writes, "Prominent white 'spectacles' adorn the blue-gray head of the solitary vireo, while the wings have two light bars. In the eastern race, which migrates across much of Texas ... the head color contrasts strongly with a greenish back. White underparts are marked with greenish yellow on the sides and flanks. A Rocky Mountain race ... called the 'plumbeous form,' ... is more iniformly lead gray above, without the contrast between head and back." But the plumbeous form occupies the Trans-Pecos, far from here.
