You have to admire the Slate-coloured, Dark-Eyed Junco. While many of our backyard birds are flying south to the Southern United States, Mexico and Central America, these spunky little birds think -15C (5F) and three feet of snow is paradise.

Compared to their traditional breeding grounds in the deep Boreal forests of northern Canada where a high percentage of them spend their spring and summer breeding months, I guess the freezing temperatures and blizzards of Southern Ontario and north-eastern United States feel quite balmy to them.

These hardy, ground-feeding members of the sparrow family, with a slate-coloured top and white undersides, seem happy enough to scrounge on the ground under our bird feeders for scraps left behind by Cardinals, Blue Jays, Woodpeckers and a host of other more fussy birds that unwittingly share their discarded seed with the Juncos at our our feeders.

And if you provide the right habitat, including their favourite native plants, roosting locations, a fresh source of water and a good source of food, you may be able to convince these little guys to stick around your woodland year round.

How long do Juncos live

No one said their lives were easy, but they have been known to survive in these harsh conditions for up to 11 years of age. Experts predict a life span of between 3-11 years depending on climate conditions, predation and other factors.

How did Juncos get their name?

Their name is derived from the Latin word juncus which is Spanish for “rush.” The dark-eyed junco’s latin name (Junco hymelalis) actually means winter junco from the Latin work hyemalis which translates “of the winter.”

Juncos are ground feeders so leave your leaves

In the fall and especially the spring, you’ll most often see these ground-feeders rooting through the fallen leaves looking for insects to feed nestlings. Leaving your fallen leaves is critical for ground-feeding birds like Juncos. Here is an earlier article on why we should be leaving our leaves where they fall.

Actually these birds are quite widespread and are found throughout the north America from Alaska to Mexico, California to New York and from one end of Canada to the other. You can expect to find them in coniferous and mixed forests, but they are just as happy in scrub land along rural roadways and, of course, flitting about in the lower shrubbery of our woodland gardens.

They certainly are not flashy birds and often go unnoticed in the garden accept when they briefly flash their white outer tail feathers thought to confuse predators during an aerial attack.

How did Juncos earn the name: Snowbirds?

Juncos, are also lovingly known by many as snowbirds, since they seem to appear along with the first snowfall of the season. Apparently, even famed birder John James Audubon called them the snowbird.

I like to think that they earned their name before the term “snowbirds” was popularized by Canadian seniors heading south in winter. I think their colouring earned them the name “Snowbirds.” The Junco’s slate-coloured plummage on their backs (the males are darker than the females) and white undersides are often associated with the leaden stormy skies of winter above and fresh snow below. That’s a much nicer interpretation than a bunch of us old Canadians heading to Florida, considering few Juncos even make it that far during migration.

While these hardy little birds are more than willing to take on our frigid temperatures than most birds, not all dark-eyed Juncos arrive from the depths of the Canadian northern forests. In some areas they are year-round residents.

In fact, in our Southern Ontario woodland, Juncos are year-round visitors. Although some of them choose to stay year-round, there certainly is an influx in fall as winter approaches. They are also more noticeable as their activity picks up during or immediately after a snowstorm.

This little female Junco searches for seeds under native Northern Sea Oat grasses. These little birds will even spend the night tucked into the grasses to escape cold winds.

In the more northern areas of the U.S. in New England and Minnesota, for example, early migrants start arriving as early as August but the more northerly birds don’t start their overnight migrations until late October and November. By December the migration is completed but some birds who migrated into parts of Ontario and the northern states may move farther north in particularly bad winters.

At our hopper feeders and tray feeder, Juncos tend to go after the black-oil sunflower, that are easily cracked with their stout, light pink bills. If given the chance, though, they are not opposed to stealing suet from the larger woodpeckers and blue jays if the suet feeders are left unattended.

In our neck of the woods, the slate,dark-eyed Junco dominates, but you may not know that there are actually two species of Juncos in North America and seven sub-species. The two species are the Slate-coloured, dark-eyed that make up about 99 per cent of the birds in North America, with a small number of yellow-eyed Juncos taking up residence in South-East Arizona. the Oregon dark-eyed Junco is the other dominant sub-species found mostly in Western United States. It sports a dark hood, a brown back and rufous flanks. Others include the Pink-Sided Junco and the White-Winged dark eye junco.

Chipmunk feeding

In our garden, the Juncos like to hang out in groups of anywhere from a few individuals to as many as 30. these groupings or small flocks feed over a territory of about 10 acres in the wild, a smaller area if food is abundant at backyard feeders.

This winter I have noticed that the Juncos are particularly attracted to our DIY heated bird bath. Without a doubt they are the most regular visitors to the bird bath – either coming down to get a drink of water or occasionally stopping by for a quick bath. My DIY heated bird bath was a simple and inexpensive project that has not only improved habitat for our local birds, but also helped to bring them in close to our home and provided me with opportunities to photograph the birds up close.

Every flock has a dominance hierachy with adult males at the top, followed by juvenile males, adult females followed by young females. Although this sounds potentially cruel, male juncos tend to stay in more northern areas to stay close to their traditional mating territories, while females migrate further south for better food sources. Females also don’t need to return to defend the breeding rounds until later in the spring so, can afford to migrate further south.

And, no need to feel sorry for the males having to tough out the colder temperatures. Juncos have their own way to deal with the cold by adding close to 30 per cent more feather weight to prepare for winter. These members of the sparrow family are between 5-6 inches and way in at about 1/2 an ounce to 1 ounce. They will also team up with flock mates in particularly harsh temperatures, seeking cover in thick evergreens, tucked into tall grasses or brush piles to get protection from the winds.

I often see them going into our cedar hedge throughout the day and into the evening. Lately, during a heavy cold spell and high snow cover, I’ve noticed them hanging out in our wood pile that has a nice layer of fall leaves providing a solid roof covering in some areas. During heavy snow, Juncos will often tuck into the small chambers formed inside tall ornamental grasses. Just another good reason to leave your ornamental grasses standing throughout the winter, waiting until later in the spring to cut them down.

Where do Juncos nest?

As spring rolls around, males begin attracting a mate with their calls – a musical trilling of between 7-23 notes that lasts a couple of seconds at a time and is repeated over and over for up to half an our, often from a high branch.

The pairs are monogomous for that breeding period, but females will pick a new mae each breeding season. The female chooses the nest site and constructs it over a period of three to seven days, before laying 3-6 eggs. In woodlands, nests are typically either on the ground or near the ground, on a rockface or possibly in cavities of an uprooted tree. In more urban areas, Juncos may choose to build their nest in hanging baskets, on light fixtures, in the eves of buildings or on window ledges.

Incubation takes about two weeks and both parents feed the babies for about 14 days in the nest and several weeks after they fledge. Male Juncos will aggressively defend the nest against marauding birds during this time. Their alarm call sounds more like a scene out of star wars, with a buzzy Que, que que que call. In flight, you might pick up a soft, buzzing trill.

Presently, it is believed that their are 200 million breeding birds with roughly 80 per cent breeding within the boreal forest. Although, like all songbirds, their numbers are in decline, they are not listed as a conservation concern.

Nevertheless, it is imperative that gardeners continue to restore the native habitat for Juncos and other native birds.

Although Juncos are primarily seed eaters, about 75 per cent of their diet consists of seed either wild or provided in our feeders, they will shift their diets primarily to insects (beetles, moths, caterpillars etc) during the breeding and nest-rearing periods.

If you are looking to plant native to provide them with a natural seed sources, consider Goldenrod, chickweed, sorrel and lambs quarter.
