Black-capped Vireo
The black-capped vireo (''Vireo atricapilla'') is a small bird native to the United States and Mexico. It was listed as an endangered species in the United States in 1987. Successful conservation efforts on the U.S. Army's Fort Hood and Fort Sill led to delisting the black-capped vireo in 2018. The IUCN lists the species as vulnerable. Description The black-capped vireo is a songbird about 12 cm (4.5 inches ) in length. Sexually mature males are olive green above and white below with faint yellow flanks. The crown and upper half of the head is black with a partial white eye ring and lores. The iris is brownish-red and the bill is black. Females are duller in color than males and have a slate-gray crown and underparts washed with greenish yellow. First-year males often have more extensive gray in the cap, similar to adult females. Nesting The male and female in a pair assist in nest construction and incubation. Typically, the female lays three or four eggs. The inc ...

Samuel Washington Woodhouse
Samuel Washington Woodhouse (June 27, 1821 – October 23, 1904) was an American surgeon, explorer and naturalist. Woodhouse was doctor and naturalist on the Sitgreaves Expedition led by Captain Lorenzo Sitgreaves from San Antonio to San Diego which explored the possibility of a route from the Zuni River to the Pacific.Woodhouse ''Texas to San Diego'' He was the author of ''A Naturalist in Indian Territory: The Journal of S. W. Woodhouse, 1849-50''. Woodhouse's toad (''Anaxyrus woodhousii'') and Woodhouse's scrub jay (Aphelocoma woodhouseii) were named in his honor. The first Cassin's Sparrow was described in 1852 by Samuel W. Woodhouse from a specimen collected near San Antonio, Texas. Dr. Woodhouse gave it its species name in honor of John Cassin, a Philadelphia ornithologist. Notes References *Woodhouse, S.W., edited and annotated by Andrew Wallace and Richard H.

Edwards Plateau
The Edwards Plateau is a geographic region at the crossroads of Central Texas, Central, South Texas, South, and West Texas. It is bounded by the Balcones Fault to the south and east, the Llano Uplift and the Llano Estacado to the north, and the Pecos River and Chihuahuan Desert to the west. San Angelo, Texas, San Angelo, Austin, Texas, Austin, San Antonio, and Del Rio, Texas, Del Rio roughly outline the area. The southeast portion of the plateau is known as the Texas Hill Country. Natural history The bedrock consists primarily of limestone, with elevations ranging between 100 and 3000 ft. Caves are numerous. The landscape of the plateau is mostly savanna scattered with trees. It mostly lacks deep soil suitable for farming, though the soil type is fertile mollisol, so some cotton, grain sorghum, and oats are grown. For the most part, though, the thin soil and rough terrain areas are primarily grazing regions, with cattle, sheep, and goats (Angora goat, Angora and meat ty ...

Birds Described In 1852
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Endemic Birds Of Southwestern North America
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vireo (genus)
''Vireo'' is a genus of small passerine birds restricted to the New World. Vireos typically have dull greenish plumage (hence the name, from Latin ''virere'', "to be green"), but some are brown or gray on the back and some have bright yellow underparts. They resemble wood warblers apart from their slightly larger size and heavier bills, which in most species have a very small hook at the tip. The legs are stout. Most species fall into two plumage groups: one with wing bars and yellow or white eye rings, and one with unmarked wings and eye stripes; however, the Chocó vireo has both wing bars and eye stripes. Sexes are alike in all species except for the black-capped vireo, in which the male's crown is black and the female's is gray. Taxonomy The genus ''Vireo'' was introduced in 1808 by the French ornithologist Louis Jean Pierre Vieillot. The type species was subsequently designated as the white-eyed vireo (''Vireo griseus'') by German ornithologist Hans Friedrich Gadow in 188 ...

Balcones Canyonlands National Wildlife Refuge
Balcones Canyonlands is a national wildlife refuge located in the Texas Hill Country to the northwest of Lago Vista, Texas. The refuge was formed in 1992 to conserve habitat for two endangered songbirds, the golden-cheeked warbler and the black-capped vireo, and to preserve Texas Hill Country habitat for numerous other wildlife species. The refuge augments a similarly named preserve in Austin called the Balcones Canyonlands Preserve. The refuge is located within a deeply dissected portion of the Edwards Plateau that contains many steep-banked streams and canyons. The canyons facing Austin are deeply etched into the limestone of the Edwards Plateau by tributaries of the Colorado River. Beneath the surface of the Edwards Plateau lies an underground labyrinth of caves, sinkholes, and springs. Various spiders, beetles, and other creatures inhabit this below-ground world, and are unique to this area of Texas. Even deeper below the surface lies the Edwards Aquifer, which stores bil ...

Brood Parasite
Brood parasites are animals that rely on others to raise their young. The strategy appears among birds, insects and fish. The brood parasite manipulates a host, either of the same or of another species, to raise its young as if it were its own, usually using egg mimicry, with eggs that resemble the host's. The evolutionary strategy relieves the parasitic parents from the investment of rearing young. This benefit comes at the cost of provoking an evolutionary arms race between parasite and host as they coevolve: many hosts have developed strong defenses against brood parasitism, such as recognizing and ejecting parasitic eggs, or abandoning parasitized nests and starting over. It is less obvious why most hosts do care for parasite nestlings, given that for example cuckoo chicks differ markedly from host chicks in size and appearance. One explanation, the mafia hypothesis, proposes that parasitic adults retaliate by destroying host nests where rejection has occurred; there is ...

Brown-headed Cowbird
The brown-headed cowbird (''Molothrus ater'') is a small, obligate brood parasitic icterid native to temperate and subtropical North America. It is a permanent resident in the southern parts of its range; northern birds migrate to the southern United States and Mexico in winter, returning to their summer habitat around March or April. Taxonomy The brown-headed cowbird was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1775 in his '' Histoire Naturelle des Oiseaux'' from a specimen collected in the Carolinas. The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Naturelle'', which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name, but in 1783, Dutch naturalist Pieter Boddaert coined the binomial name ''Oriolus ater'' in his catalogue of the ''Planches Enluminà ...
