dark-eyed junco

On 7 July 2018 at 11:48 MDT, while walking in the Rattlesnake Creek drainage near the north end of Missoula, Missoula County, Montana, my attention was drawn to a pair of Dark-eyed Juncos (Junco hyemalis) about 20 m distant emitting a series of "tik" calls (Hostetter 1961; Nolan and others 2002) as they fluttered and perched low to the ground; they were accompanied by a pair of Chipping Sparrows (Spizella passerina), which also were vocalizing and acting agitated, but the sparrows did not fly to the ground with the juncos.

Nine other species breed only locally in the Arctic: Horned Grebe, Leach's Storm-petrel, Swainson's Hawk, Great Horned Owl, Northern Hawk Owl, Gray Jay, Palm Warbler, Orange-crowned Warbler, and Dark-eyed Junco. The Northern Fulmar (collected at Cape Kellett), Swainson's Hawk (collected at Bernard Harbour), Orange-crowned Warbler (collected at Cape Hope, Nunavut), Palm Warbler (collected at Bernard Harbour), and Dark-eyed Junco (collected at Tree River and at Bernard Harbour) were collected from localities that lie far outside the species' known distribution ranges (Godfrey, 1986), indicating rare, stranded individuals in the far Arctic.

(1973) and the second-most common species behind dark-eyed juncos in our study.

The prominence of Dark-eyed Juncos, White-throated Sparrows and Swainson's Thrushes did, however, greatly increase the relative importance of ground-brush foragers.

Specific habitat types such as old growth forests and hemlock ravines were found to be important to several of these species, namely, Winter Wren, Magnolia Warbler, Cerulean Warbler, Canada Warbler, and Dark-eyed Junco. Further, large blocks of appropriate habitat were available for some species intolerant of fragmentation, such as Wood Thrush and Bobolink.

The seven study species represented all species that nested on the ground or in shrubs in the understory on these sites: Virginia's Warbler (Vermivora virginiae), Dark-eyed Junco (Junco hyemalis), Red-faced Warbler (Cardellina rubifrons), Orange-crowned Warbler (Vermivora celata), Green-tailed Towhee (Pipilo chlorurus), MacGillivray's Warbler (Oporornis tolmei), and Hermit Thrush (Catharus guttatus).

Then a decision was made that slate-colored juncoes and the Oregon junco should really be considered variants of the same species, the dark-eyed junco. The slate-colored junco seems rather drab in its plumage: gray head and back (darker gray in males), white underneath.

They whooped with joy as the dark-eyed Junco bird, blown off course by gales, made a series of appearances in the garden.

Conifer habitats had no significant indicator species associated only with this habitat, but they shared four significant indicator species typical of coniferous forest (Dark-eyed Junco Junco hyemalis, Chipping Sparrow Spizella passerina, Gray Jay Perisoreous canadensis, and Hermit Thrush Catharus guttatus) with wetland sites.
