Vireo plumbeus
The Plumbeous Vireo (Vireo plumbeus) is a subtly elegant New World passerine, characterized by its understated lead-gray plumage, a distinguishing feature that gives it its scientific name. Measuring approximately 5-6 inches (13-15 cm) in length with a wingspan of 9-10 inches (23-25 cm) and weighing around 0.4-0.6 oz (10-17 g), it possesses a robust, slightly hooked bill and strong legs. Key identification marks include prominent white spectacles (bold white eye-rings connected by a narrow wh...
This vireo primarily inhabits arid to semi-arid montane woodlands, favoring open pine-oak, pinyon-juniper, or Douglas-fir forests, typically at elevations between 4,000 and 9,000 feet (1,200-2,700 meters).
Primarily insectivorous, feeding on a wide variety of arthropods, including caterpillars, beetles, spiders, and grasshoppers, supplemented with small fruits and berries during late summer and fall. They forage by slow, methodical gleaning from foliage and bark.
Plumbeous Vireos are diurnal and generally solitary outside of the breeding season, though they may join mixed-species foraging flocks during migration. Their foraging strategy is characterized by a slow, deliberate gleaning of insects from foliage, branches, and occasionally bark, often hanging ...
The Plumbeous Vireo's breeding range extends across the montane western United States, primarily throughout the Rocky Mountains, Great Basin, and Southwest. This includes states like Arizona, New Mexico, Colorado, Utah, Nevada, Idaho, Wyoming, and parts of California, Oregon, and Montana. Southwa...
