What Do Juncos Eat? (Complete Guide)

Juncos are one of the most widespread songbirds. Their range covers much of the North American continent, reaching from northern Canada and Alaska, across the United States, and into regions of northern Mexico.

Juncos diets vary based on which time of the year is. In summer, when breeding, their diets primarily consist of insects and seeds from common plants. When it gets a bit colder in fall and autumn, they feed on mainly grasses and weeds.

Juncos are often affectionately referred to as snowbirds. They spend long summer days in the breeding grounds of mountain forests and the Northwoods, where they feast on insects and seeds from common plants. Then, once winter sets in, Juncos can be found in the woodland edges, thickets, and suburban areas across much of the midwest and southeast. This time of year, juncos feed mainly on the seeds of weeds and grasses. They are also frequent visitors to backyard bird feeders.

The majority of a junco’s year-round diet comes from the seeds of plants such as sorrel, buckwheat, and lamb’s-quarters.

Are juncos ground feeders?

Juncos are mainly ground feeders. They prefer to forage for insects and seeds on the ground rather than while flying or perching.

If you were hoping to attract juncos with a bird feeder, though, don’t be disheartened. They are common backyard visitors and may very well choose to stop by your feeder. However, you are far more likely to see flocks of them picking up fallen seeds from underneath the bird feeder.

How do juncos find food?

Juncos are natural foragers. They mainly search for their food on the ground, snatching tasty insects or seeds as they find them. Occasionally a junco may grab a juicy berry while flying by a fruiting bush.

How often do juncos eat?

Juncos will frequently eat throughout the day when they are most active. They are likely to forage even more often when feeding chicks.

If Juncos are visiting your backyard in winter, you will likely see several in a flock foraging together. You may even see several different varieties, depending on where you live. Juncos from the east sport different colors and patterns than those in the west, but they overlap in some midwest states.

What do baby juncos eat?

Baby juncos eat a diet of insects. Both males and females share the responsibility of feeding. After about two weeks, the fledgling juncos have learned how to fly and are ready to leave the nest.

Juncos are well adapted to nesting and foraging in residential areas, even busier suburban ones. If you keep an eye out, you may get to witness a pair feeding their chicks or fledglings leaving the nest.

What can I feed juncos?

Now that we have discussed their natural diet let’s talk about what you can feed juncos.

When it comes to birdseed, juncos tend to prefer hulled sunflower seeds, white proso millet, safflower seeds, and cracked corn. Any combination of these particular seeds will likely attract juncos to your backyard.

It is important to remember that juncos are ground feeders. Sprinkling seed on the ground is typically the best way to ensure these birds visit you. But, say you have cats or other predators nearby, juncos will also eat from low platform feeders or open trays.

What do juncos drink?

Juncos prefer fresh water to drink. It is relatively easy for them to find suitable water sources within their habitat. They may even melt snow in their bills for a drink on the go.

However, providing visiting juncos a birdbath full of fresh water will certainly be appealing to them. It will attract many other fun birds as well. You can even offer a heated birdbath to ensure the water will not freeze in winter.
