Aptly named, the solitaire is usually seen alone sitting high in a coniferous tree looking much like a large flycatcher. During the summer, it is confined to high and steep mountain sides where it nests in steep banks amid trees roots. The nest itself is made of twigs and grass stems, and the young are fed insects and an occasional worm. However, in the winter the solitaire descends to lower elevations and feeds almost exclusively on berries, especially those of juniper trees.
The four-digit banding code is TOSO.
