Junco

A junco /ˈdʒʌŋkoʊ/, genus Junco, is a small North American bird. Junco systematics are still confusing after decades of research, with various authors accepting between three and 12 species. Despite having a name that appears to derive from the Spanish term for the plant genus Juncus (rushes), these birds are seldom found among rush plants, as these prefer wet ground, while juncos like dry soil.

"Junco" is also a shrub in the genus Adolphia and the Spanish term for rushes (genus Juncus).

Their breeding habitat is coniferous or mixed forest areas throughout North America, ranging from subarctic taiga to high-altitude mountain forests in Mexico and Central America south to Panama. Northern birds usually migrate farther south; southern populations are permanent residents or altitudinal migrants, moving only a short distance downslope to avoid severe winter weather in the mountains.

These birds forage on the ground. In winter, they often forage in flocks. They eat mainly insects and seeds. They usually nest in a well-hidden location on the ground or low in a shrub or tree.

Systematics
  • Dark-eyed junco (Junco hyemalis)—the Latin name literally means wintery junco, as the species was first described in southern North America, where the bird migrates to in the winter.
    • Gray-headed junco (J. h. caniceps)—sometimes considered either a separate species (J. caniceps) or a separate species with two subspecies (see fourth line below). Caniceps in Latin means gray-headed.
    • Oregon juncos, J. h. oreganus subspecies group—sometimes considered a separate species (J. oreganus) with seven or eight subspecies (see third line below)
    • Pink-sided junco (J. h. mearnsi)—sometimes included within the oreganus subspecies group
    • Red-backed junco (J. h. dorsalis)—sometimes included within J. h. caniceps as the gray-headed juncos, J. h. caniceps subspecies group, or sometimes considered either a separate species (J. dorsalis) or a separate species (J. caniceps) with two subspecies (see first line above)
    • Slate-colored juncos, J. h. hyemalis subspecies group—sometimes considered a separate species with either two or three subspecies
    • White-winged junco (J. h. aikeni)—sometimes considered a separate species
  • Guadalupe junco, Junco insularis
  • Yellow-eyed junco (Junco phaeonotus)
    • Arizona yellow-eyed junco (J. p. palliatus)
    • Chiapas yellow-eyed junco (J. p. fulvescens)
    • Guatemalan yellow-eyed junco (J. p. alticola)
    • Mexican yellow-eyed junco (J. p. phaeonotus)
  • Baird's junco (Junco bairdi)
  • Volcano junco (Junco vulcani)
gollark: The thing shipped with potatOS uses events, timing *and* memory addresses.
gollark: Yes, I suppose technically the state has absolutely no effect on what it does, hmmm.
gollark: muahahaha.
gollark: ```lualocal function statefulize(fn) local state = 0 return function(...) state = state + 1 fn(...) endend```
gollark: \so it's probably fine.
