Dull gray vireo with bold white spectacles. Relatively thick bill and slower movements help separate this bird from other small songbirds. Combination of white spectacles and plain gray color distinguish Plumbeous from other vireos. Only sometimes shows a faint yellowish wash on the sides. Resident populations in northern Central America are brighter (much like Cassin's Vireo), but not as bright and contrasty as Blue-headed Vireo, which occurs there in winter. Found in coniferous and mixed forests.
