Dark-eyed Junco: More than Meets the Eye

dark-eyed junco

How many junco species exist worldwide?

a) 3
b) 5
c) 12
d) Somewhere between 3 and 12

Answer: b) for now. Junco systematics is still being sorted out, but the American Ornithological Union, the American Birding Association, Clements Checklist, and eBird all recognize five junco species (Baird’s, dark-eyed, Guadalupe, volcano, and yellow-eyed). DNA testing might reveal a different answer in a few years.
