There are two species of juncos in North America. The Yellow-eyed Junco is one of them and the Dark-eyed Junco has at least seven sub-species in its group. They are the Cassiar Junco, Gray-headed Junco, Oregon Junco, Pink-sided Junco, Red-backed Junco, Slate-colored Junco and the White-winged Junco.
The juncos behave in the same fashion as sparrows. They are seen most often on the forest floor where they spend their days searching through the fallen leaves looking for insects and other food. In early spring and later in the fall these same birds will show up at the backyard birdfeeders as they migrate to their summer or winter grounds.
ABA - American Birding Association This site represents an organization that maintains official records of all birds species that have been proven to have been seen inside the perimeters of the North American Continent and the surrounding bodies of water. Regular revised versions are posted to keep the bird list current at all times. This is the list used by all serious birders over their lifetime. You may be aware of the movie called the "Big Year". It was with this list that all the competing birders used in an attempt to set a new record as to how many bird species that could be seen by an individual birder in one calendar year.
