Nolan et al. 2002). The same might be said today.
Not surprisingly, with such a large range, juncos show much geographic variation Up until the 1970s, ornithologists recognized 5 species of what is now called the Dark-eyed Junco. Now these former species are lumped into a single species, with 15 subspecies. Several of these have been recorded in Minnesota. But the most common eastern form, which used to be named the Slate-colored Junco, is the most abundant here. This form is what Erika and I photographed last week in the University of Minnesota Landscape Arboretum.
