Includes Guadalupe Junco

[edit] Identification

5-6 1/4 in (13-16 cm) This species shows much geographic variation in color, with many recognized populations or subspecies. All are easily recognizable as Juncos, due to the body shape and behavior. The subspecies are named and grouped variously depending on the authority listing them, but the following four major designations are common:

[edit] Oregon Junco

[edit] Slate-colored Junco

Populations in the Southwest. Gray overall, with reddish-brown back.

[edit] Distribution

Northern birds migrate further south; many populations are permanent residents or altitudinal migrants. In winter, juncos are familiar in and around towns. The "Slate-coloured" Junco is a rare vagrant to western Europe and has wintered in Great Britain, usually in a domestic garden.

[edit] Taxonomy

The best-known species of junco, a genus of small American sparrows.

Until recently the many geographical forms of this bird were considered separate species, but since they interbreed wherever their ranges meet, they are now considered one species.
The subspecies insularis from Guadalupe Island is sometimes still considered a separate species, Guadalupe Junco.

[edit] Habitat

Openings and edges of coniferous and mixed woods; in winter, fields, roadsides, parks, suburban gardens.

[edit] Behaviour

This lively territorial bird is a ground dweller and feeds on seeds and small fruits in the open. It also moves through the lower branches of trees and seeks shelter in the tangle of shrubs.

[edit] Nesting

3-6 pale bluish or greenish eggs, with variegated blotches concentrated at the larger end, in a deep, compact nest of rootlets, shreds of bark, twigs, and mosses, lined with grasses and hair, placed on or near the ground, protected by a rock ledge, a mud bank, tufts of weeds, or a fallen log. Incubation lasts about 12 days by the female only. Young juncos leave the nest from 10 to 13 days after hatching. These birds often have 2 to 3 broods a summer.

[edit] Diet

Insects, seeds, and berries.
