Guide to North American Birds
Conservation status Abundant and widespread.
Family New World Sparrows
Habitat Conifer and mixed woods. In winter, open woods, undergrowth, roadsides, brush. Over its wide range, breeding habitat is consistently coniferous or mixed woodland, usually in rather open situations such as edges or clearings. Winters in many kinds of semi-open habitats including woodland edges, thickets, brushy places, suburban areas.
In winter over much of the continent, flocks of Juncos can be found around woodland edges and suburban yards, feeding on the ground, making ticking calls as they fly up into the bushes. East of the plains the Juncos are all gray and white, but in the West they come in various color patterns, with reddish-brown on the back or sides or both; some of these were once regarded as different species. The forms have separate ranges in summer, but in winter several types may occur in the same flock in parts of the West.

Feeding Behavior

Forages mostly while hopping and running on the ground. Sometimes scratches with its feet in leaf-litter or snow. Will come to bird feeders, but tends to forage on the ground under the feeding tray.


Eggs

3-5, rarely 6. Whitish to bluish white or pale gray, with markings of brown and gray often concentrated at larger end. Incubation is by female, about 11-13 days. Young: Both parents feed the nestlings. Young leave the nest 9-13 days after hatching. 1-2 broods per year, sometimes 3.


Young

Both parents feed the nestlings. Young leave the nest 9-13 days after hatching. 1-2 broods per year, sometimes 3.

Diet

Mostly seeds and insects. Close to half of summer diet of adults consists of insects, including caterpillars, beetles, grasshoppers, true bugs, and others, also spiders. Feeds heavily on seeds of weeds and grasses, especially in winter. Also eats some berries. Young are fed mostly insects.


Nesting

Male sings from high perch to defend nesting territory. In courtship, both members of pair may hop about on ground with wings drooped and with tail spread widely to show off white outer tail feathers; male may give soft song. Nest site is almost always on ground, well hidden under overhanging grass, under log, rock, or exposed roots, or in shallow hole in dirt bank. Sometimes up in shrub, tree, or ledge of building, rarely more than 10' above ground. Nest (built mostly by female) is an open cup of grass, weeds, leaves, lined with fine grass and sometimes with hair or feathers.

Migration

Most populations are migratory, but some in southwestern mountains and on southern Pacific Coast may be permanent residents. Males tend to winter slightly farther north than females.

How Climate Change Will Reshape the Range of the Dark-eyed Junco

Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.

Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
