Junco
A junco (), genus ''Junco'', is a small North American bird in the New World sparrow family Passerellidae. Junco systematics are still confusing after decades of research, with various authors accepting between three and twelve 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, which prefer wet ground, while juncos prefer dry soil. 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-hid ...

Junco Hyemalis
The dark-eyed junco (''Junco hyemalis'') is a species of junco, a group of small, grayish New World sparrows. The species is common across much of temperate North America and in summer it ranges far into the Arctic. It is a variable species, much like the related fox sparrow (''Passerella iliaca''), and its systematics are still not completely resolved. Taxonomy The dark-eyed junco was formally described by the Swedish naturalist Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' as ''Fringilla hyemalis''. The description consisted merely of the laconic remark "''F ingillanigra, ventre albo.'' ("A black 'finch' with white belly") and a statement that it came from America. Linnaeus based his description on the "Snow-Bird" that Mark Catesby had described and illustrated in his 1731 ''The Natural History of Carolina, Florida and the Bahama Islands''. The Bill of this Bird is white: The Breast and Belly white. All the rest of the Body black; but in some places ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Junco Bairdi
Baird's junco (''Junco bairdi'') is a species of junco, a group of small, grayish New World sparrows. It is endemic to the forests in the higher elevations of the Sierra de la Laguna mountain range of the southern Baja California peninsula in Baja California Sur, Mexico. Taxonomy and systematics While originally described as a distinct species, it was once considered a subspecies of the yellow-eyed junco (''Junco phaeonotus'') before being recognized as a distinct species again in 2014 by the AOS after further research. Within the genus junco, Baird's junco is the outgroup to all other juncos with the exception of the volcano junco, having diverged from other members of the genus more than 350,000 years ago despite retaining a phenotype similar to other North American juncos. Etymology The type specimens of Baird's junco were collected on February 2, 1883, by Lyman Belding at "Laguna, Lower California" Baja California and it was named for Spencer Fullerton Baird, an American or ...

Guadalupe Junco
The Guadalupe junco (''Junco insularis'') is a small bird in the New World sparrow family that is endemic to Guadalupe Island off the western coast of Baja California, Mexico. Many taxonomic authorities classified it in 2008 as a subspecies of the dark-eyed junco (''Junco hyemalis''). In 2016, it was re-classified as a full species. Description and ecology The Guadalupe junco has a dull grayish head with a gray bill and brownish upperparts. Its wings and tail are blackish, though the tail has white edges. Its underparts are white with a rufous fringe at the bottom of the wings. It makes a high, sharp ''sik'' and a long series of chipping notes. This bird is today found mainly in the Guadalupe cypress (''Cupressus guadalupensis'') groves on Guadalupe Island, with a few birds in the remaining Monterey pine (''Pinus radiata'') stands. Around 1900, it was known to utilize almost any habitat for breeding. It ranged over the whole island for feeding then, and indeed still does theoret ...

Yellow-eyed Junco
The yellow-eyed junco (''Junco phaeonotus'') is a species of junco, a group of small New World sparrows. Its range is primarily in Mexico, extending into some of the mountains of the southern tips of the U.S. states of Arizona and New Mexico. It is not generally migratory, but sometimes moves to nearby lower elevations during winter. The female lays three to five pale gray or bluish-white eggs in an open nest of dried grass two to three times a year. Incubation takes 15 days, and when hatched, the chicks are ready to leave the nest two weeks later. This bird's diet consists mainly of seeds, berries and insects. Taxonomy The yellow-eyed junco was species description, formally described in 1831 by the German naturalist Johann Georg Wagler from a specimen collected in Mexico. He introduced a new genus, ''Junco'', and coined the binomial name ''Junco phaeonotus''. The genus name is from Latin ''iuncus'' meaning "rush". The specific epithet combines the Ancient Greek '' phaios'' mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcano Junco
The volcano junco (''Junco vulcani'') is a New World sparrow endemic to the Talamancan montane forests of Costa Rica and western Panama. This junco breeds above the timberline, typically at altitudes above 3,000 m, but there is an isolated population at 2,100 m on the Caribbean slope of Costa Rica and forest clearance on Cerro de la Muerte has allowed this species to descend to 2,600 m. The habitat is open grassy or brushy areas with some stunted scrubs. The nest is a neat, lined cup constructed on the ground under a log, bush or rock, or in a cavity on a vegetated bank. The female lays two brown-spotted pale blue eggs. The volcano junco is on average 16 cm long and weighs 28 g. The adult has brown upperparts with dark streaking especially on the back. The wings and tail feathers are dark fringed. The underparts are grey. The sides of the head are grey with a black mask through the eye, a yellow iris, and a pink bill and legs. Young birds are brighter bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
