Juncos are small, gray and white colored birds that are a common sight across North America. With their distinctive plumage and bright white tail feathers that flash as they fly, juncos add a pop of animation and color to backyards and open landscapes. If you enjoy birdwatching and nature photography, capturing images of these active and abundant songbirds can be highly rewarding. This photo gallery provides a close-up look at the junco’s appearance, behaviors, habitat, and role in ecosystems across the seasons.
Overview and Identification of Juncos
The junco is a member of the sparrow family and is known for its slate-colored upper body, lighter belly, and conspicuous white outer tail feathers. Several subspecies occur across North America, varying somewhat in their plumage details but all sharing the same general appearance.
Some tips for identifying juncos include:
- Size: About 6 inches long from beak to tail tip.
- Shape: Round, full body shape. Large conical bill.
- Color: Slate gray head, back, wings and tail with a lighter underside. White outer tail feathers that flash visibly in flight.
- Behavior: Ground foragers often seen hopping and bounding on open ground in small flocks.
Dark-Eyed Junco Subspecies
While the dark-eyed junco species shares common traits, some key differences occur among regional subspecies in the United States:
- Slate-colored: Eastern and central US and Canada. Gray upper body and white belly.
- Oregon: West coast. Darker gray head and back with more buff color on sides.
- Pink-sided: Great Plains, Rockies. Slate back with pink-buff flanks.
- White-winged: Upper Midwest and Appalachians. Bold white wing bars.
- Gray-headed: Southwest. Gray hood, brown back, reddish sides.
Juncos in Their Natural Habitat and Ecosystems
Juncos thrive in open, elevated habitats across North America including:
- Coniferous and mixed forests.
- Mountain meadows and scrublands.
- Backyards, parks and gardens.
- Roadsides and grassy fields.
Some key facts about juncos and their natural habitats:
- Forage on the ground for seeds and insects. Constantly hop and scratch at the soil surface.
- Nest on or near the ground hidden in rock piles, brush, grass and roots.
- Roost in conifers and shrubs. Seek cover in trees and woods.
- Migrate in flocks from northern boreal forests to spend winter across the U.S.
- Play a role distributing seeds and keeping insect populations in balance as part of food webs.
- Coexist with other ground foragers like sparrows, towhees and bobolinks in the same habitats.
Junco Behavior and Feeding Habits
The active, ground-dwelling lifestyle of the junco lends itself to captivating photography opportunities.
Foraging and Feeding
- Feed primarily on seeds from grasses, shrubs, conifers. Will eat berries and insects too.
- Constantly scratch and scuffle through leaf litter searching for food items.
- Form loose flocks that work through an area feeding together and keeping watch for predators.
- Make short flights across open areas between sources of cover as they feed.
- Males will bring seeds and insects to females during courtship and nesting seasons.
Roosting and Preening
- Seek dense conifers for nighttime roosts and shelter in bad weather.
- Make short flights to reach daytime perches in shrubs, fences and rocks.
- Preen feathers frequently to keep them in good condition.
- Ruffle feathers and spread wings to thermoregulate in cool temperatures.
- Gather together in groups numbering from a dozen to over 100 birds.
Range and Migration Patterns
Juncos breed predominantly in Canada and Alaska and migrate south for winter all across the lower 48 states.
- Breeding range: Boreal forests, mountain parks from Alaska to Newfoundland.
- Winter range: Nearly all of lower 48 states, southward into Mexico.
- Migration: Time depends on latitude. Earlier in northern range (August – September), later farther south (October – November).
- Travel in flocks numbering from small groups of 6-12 birds up to huge flocks of several hundred.
- Stop to rest and feed during migration, especially in areas with seed-producing grasses and ground cover.
- ** Males and females migrate together** in mixed flocks.
- Juveniles migrate later, after adults, in looser flocks.
Junco plumage Details
Looking closely at the junco’s plumage reveals some beautiful patterning and coloration.
Slate-Colored Junco
The most widespread and familiar subspecies:
- Head, back, wings: Cool gray-brown. Finely mottled.
- Throat, breast: Lighter warm gray blending to buff belly.
- Bill: Pinkish buff. Eyes dark brown.
- Legs: Flesh pink.
- Tail: Long, blackish-gray with conspicuous white outer feathers.
Oregon Junco
Heavier bill and darker hood than slate-colored:
- Head, upper back: Solid blackish-gray hood and cap.
- Back, wings: Dark gray-brown.
- Sides and flanks: Pinkish cinnamon buff coloration.
- Tail: Black with white outer feathers like other subspecies.
White-winged Junco
Named for the bold white bands on its wings:
- Back: Dark brownish-slate.
- Head: Gray like other juncos.
- Wings: Obvious broad white bars on dark flight feathers.
- Belly: Pinkish buff color on breast and sides.
interesting Junco Behaviors and Interactions
Beyond feeding behaviors, juncos exhibit some intriguing interactions and displays during the breeding season.
Singing and Calls
- Dawn chorus: Males sing most actively at dawn to attract mates and defend territory.
- Song: A musical, high-pitched trill lasting 2-3 seconds.
- Call: A sharp single or double “chip” note used for staying in contact.
Courtship Displays
- Tail spreads: Males face females and spread tail, flashing white outer feathers.
- Wing flicking: Males approach females with wings slightly drooped and flicking.
- Nest displays: Males lead females to potential nest sites with swooping flights.
Territoriality and Aggression
- Males defend nesting areas with song and by chasing intruders.
- Aggressive displays like beak jabbing and spread wings used to repel rivals.
- Females may join in chasing other juncos away from the nest vicinity.
Junco Nesting, Eggs and Raising Young
During spring and summer, juncos build well-concealed nests and raise broods of young.
The Nesting Process
- Location: On the ground hidden in rocks, grass, roots, or brush piles.
- Nest building: Female builds nest of grasses and twigs lined with softer materials.
- Egg laying: 3-6 pale grayish or bluish-white eggs with dark fine spotting.
- Incubation: By female for 12-13 days until eggs hatch.
- Nestlings: Both parents feed nestlings for 11-13 days until fledging.
Caring for Eggs and Chicks
- Parents take turns incubating eggs almost continuously.
- Nestlings are born naked, blind, and helpless.
- Young birds are fed insects for protein until able to fly and feed themselves.
- Parents continue caring for fledglings on the ground for several weeks after leaving nest.
- Mortality is high, many nests fail due to weather, predators, brood parasitism.
Seasonal Changes in Juncos
The junco’s appearance and activities transform through the seasons based on breeding condition and molting.
Spring Changes
In preparation for breeding, juncos undergo changes in spring:
- Males arrive before females on breeding grounds and establish territories.
- Plumage becomes darker and more colorful. Rusty browns appear on flanks.
- Behaviors shift to courtship activities like displaying, mating and nesting.
- Singing and aggression increase as males compete for mates.
Molting and Fall Changes
In preparation for winter, juncos molt old feathers and shift in appearance:
- Molt before fall migration, late July through September.
- Males lose their darker breeding colors and resemble females.
- Juveniles replace first plumage and gain adult-like feathers.
- Flocking behavior increases, feeding focus shifts to seed sources.
Best Tips for Photographing Juncos
When trying to capture great photos of juncos, keep these tips in mind:
- Use a fast shutter speed to freeze their constant motion as they hop and flit around.
- Get down at ground level and shoot at their eye level to capture natural perspectives.
- Use bushes, rocks or grass to conceal yourself and allow juncos to relax when nearby.
- Add some seed or crumbs to attract juncos to a stakeout spot for photos.
- Mornings and late afternoons provide nice warm sunlight for photography.
- Patience is key. Juncos are easily spooked, so wait quietly for natural behaviors to unfold.
- Try whistling, squeaking or “spishing” sounds to pique their curiosity and bring them close.
- Fast continuous shooting mode lets you machine gun the action and capture peak moments.
