They have a broad habitat preference, from mixed woodlands, coniferous forests, and deciduous forests to parks, gardens, and roadsides. During winter, they migrate to the southern United States and Mexico.
5. Interesting Facts
A fun fact about Dark-eyed Juncos is despite being primarily ground feeders, they are excellent fliers and often engage in mid-air fights over territories. They are known as “snowbirds” in many regions due to their return signaling the arrival of winter. Dark-eyed Juncos have an extraordinary range of songs and sounds, which they use for different purposes like attracting mates and warning against predators.
6. Diet
Dark-eyed Juncos mainly eat seeds from weeds and grasses, but they also consume berries, insects, and small fruit. During winter, when insects are scarce, seeds make up about 75% of their diet.
7. Behavior & Sounds
They have a unique habit of flicking their tails from side to side, revealing the striking white outer tail feathers. Their song is a trill similar to the sound of a ringing telephone. They have a variety of calls, including a high “tik”, a dry rattle, and a metallic smack.
8. Conservation Status
According to the IUCN Red List, the Dark-eyed Junco is classified as a species of Least Concern. However, their numbers are reportedly declining in some areas, attributed to habitat loss and fragmentation.
9. Lifespan

10. Additional Notes
In Spanish, Dark-eyed Juncos are known as “Junco Ojioscuro”. People sometimes mistake them for sparrows, but their behaviors and nesting habits are quite different. They play a crucial role in seed dispersal in the ecosystems they inhabit, aiding in plant biodiversity. As ground feeders, they are also vital in controlling pest populations. They generally have a positive interaction with humans and are frequent visitors to bird feeders.
