he plumbeous vireo (Vireo plumbeus) is a small North American songbird, ranging from far southeastern Montana and western South Dakota south to the Pacific coast of Mexico, including the extreme southern regions of Baja California Sur. It is migratory, moving to the southern part of its range in winter, and its habitat generally encompasses open pine forests.
The plumbeous vireo is 4.75 inches (12 cm) in length, with a gray head, back, and flanks, and whitish underparts. It has a solid white eye ring and white wing bars.
The song, given persistently, consists of short, rough whistled phrases of several notes, spaced about 2 seconds apart. The phrases often alternate ending on a high note and a low note, giving an impression of question and answer.
The plumbeous vireo builds a cup nest out of bark strips and down in the fork of a twig. It lays 3 to 5 white eggs with some brown spots.
This species was formerly considered to belong to the same species as Cassin’s vireo and blue-headed vireo. At that time, this complex of species was referred to as the “solitary vireo”.
The White Mountains of Arizona are a mountain range and mountainous region in the eastern part of the state, near the border with New Mexico; it is a continuation from the west of the Arizona transition zone–Mogollon Rim, with the Rim ending in western New Mexico. The White Mountains are a part of the Colorado Plateau high country of Northeast Arizona, the Navajo Nation, with the rest of the Plateau in eastern Utah, northwest New Mexico, and southwestern Colorado. Nearby communities include Show Low, Pinetop-Lakeside, Greer, Springerville, Eagar,and McNary. Much of the range is within the Fort Apache Indian Reservation.
The highest summit is Mount Baldy, with an elevation of 11,400 feet (3,475 m). The mountains are drained to the south by several tributaries of the Salt River, and to the north by the Little Colorado River. There are several small lakes.
The part of the White Mountains outside the reservation is in the Apache-Sitgreaves National Forest.
