JUNCO YES, ‘JUNK BIRD’ NO

Nature has seen fit to populate North America with more Dark-eyed Juncos than humans. An admirable choice to my mind.
Around here the Junco breeds in both the Siskiyous and Cascades, in conifer forests mostly above 4000 feet. In San Francisco they breed beneath the transplanted pine and cypress, just above sea level.
