Junco Hyemalis Hyemalis CT1 (cropped)
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-hidde ...

Adolphia
''Adolphia'' is a genus of shrubs in the buckthorn family containing only two species. These are rigid, thorny, flowering bushes. '' Adolphia californica'' , the ''California prickbush'' or ''California spineshrub'', are native to southern California and northern Mexico. '' Adolphia infesta'' , the ''junco'', is found in Arizona, Texas, New Mexico, and northern Mexico. This genus is named for the French botanist Adolphe-Théodore Brongniart Adolphe-Théodore Brongniart () FRS FRSE FGS (14 January 1801 – 18 February 1876) was a French botanist. He was the son of the geologist Alexandre Brongniart and grandson of the architect, Alexandre-Théodore Brongniart. Brongniart's pioneeri ... (1801–1876). It was first described and published in Pl.

Taiga
Taiga (; rus, тайга́, p=tɐjˈɡa; relates to Mongolic and Turkic languages), generally referred to in North America as a boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest has been called the world's largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States. In Eurasia, it covers most of Sweden, Finland, much of Russia from Karelia in the west to the Pacific Ocean (including much of Siberia), much of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and areas of northern Kazakhstan, northern Mongolia, and northern Japan (on the island of Hokkaidō). The main tree species, depending on the length of the growing season and summer temperatures, vary across the world. The taiga of North America is mostly spruce, Scandinavian and Finnish taiga consists of ... [...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 br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baird's Junco
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 Sierra de la Laguna mountain range of the southern Baja California Peninsula in Mexico Mexico (Spanish: México), officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatema .... It was previously considered a subspecies (one of five) of the yellow-eyed junco (''Junco phaeonotus''). Baird's junco is one of several species of birds named for Spencer Fullerton Baird, an American ornithologist and naturalist. References *Chesser, R.T., K.J. Burns, C. Cicero, J.L. Dunn, A.W.

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 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'' meaning "dusky" or "bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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'') grove 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 ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dark-eyed Junco
The dark-eyed junco (''Junco hyemalis'') is a species of junco, a group of small, grayish New World sparrows. This bird is common across much of temperate North America and in summer ranges far into the Arctic. It is a very variable species, much like the related fox sparrow (''Passerella iliaca''), and its systematics are still not completely untangled. 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 ''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 dusky, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
