Here are a couple sub-species of Dark-Eyed Juncos, perching and facing the sun in my yard. All Dark-Eyed Juncos are known to be ground feeders, eating millet or thistle under bird feeders or on a platform feeder. We have many in our yard that use our reach up feeder, as well as foraging below for food. What is the difference between a species and a sub-species? For example, Dark-Eyed Junco is the species name, this is the group within which interbreeding can produce offspring. A sub-species is the same species and can interbreed, yet usually do not, for reasons such as sexual selection or geographic isolation.

Some of the sub-species of Dark-Eyed Junco’s include the Oregon Junco, which is the most widespread and are found throughout the western U.S. and Canada. The Gray-Headed Junco can be found throughout the Southwest. The Pink-Sided Junco can be found in the interior western states of the U.S. The Slate-Colored Junco is found in the eastern U.S. and Canada, and specifically Appalachian Mountains. The White-Winged Junco can be found in the Black Hills in South Dakota.

  1. We get the slate-colored in AK too! It’s the predominant kind for most of the state, though the OR type appears in southeast. I love them and their angry sewing machine calls. They’re the first bird I ever learned to identify by sound in AK.
