Blue Eyed Vireo in a nest made of lichen and rhododendron flower. This photo was taken in western North Carolina near the Blue Ridge Parkway. The nest is made of lichen Parmotrema reticulatum and rhododendron flower Rhododendron catawbiense. All three species are common in the upper elevations of the Blue Ridge and Great Smokey Mountains, but less common being found together. The Appalachian highlands are southern nesting range of the Blue Eye Vireo, and this is one of the species which may disappear from the mountains as climate change warms the mountaintops.
