Description: The song of the warbling vireo represents one of the most recognizable songs of the aspen grove. Singing incessantly, the song resembles a high pitched "brigadier-brigadier-brigate". Despite the prevalence of the song on the aspen airwaves, the warbling vireo is difficult to spot. It in unremarkable in appearance, with gray upper parts and a light underbody. The head, nape, back, wings and tail are gray. There is a white eyebrow line. The throat and belly may show a hint of yellow. They pick insects from the foliage of aspen and willows. The red-eyed vireo has more olive in the upper parts, and a black eye line. It also has a bright red eye. The nest is placed high near the tops of the aspen or poplar. The nest is suspended by its rim from a fork in the branch.
