Gray Vireo
The gray vireo (''Vireo vicinior'') is a small North American passerine bird. It breeds from the southwestern United States and northern Baja California to western Texas. It is a migrant, wintering in northwestern Mexico, in western Sonora state, and the southern Baja Peninsula in Baja California Sur; it remains all year only in Big Bend National Park in southwest Texas. It is usually found at altitudes between in its Mexican breeding grounds. This vireo frequents dry brush, especially juniper, on the slopes of the southwestern mountains. Description The gray vireo is in length, gray above, and dull white below, with a single faint wing bar and an eye-ring. It has a short, thick bill. Sexes are similar. The sideways twitching of its tail is unique among vireos and is reminiscent of that of gnatcatchers. The song is ''hu-wee, chu-wee, che-weet, chee, ch-churr-weet'', ''churr'', ''schray''. Behavior The gray vireo has skulking habits and is difficult to observe in the dense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elliott Coues
Elliott Ladd Coues (; September 9, 1842 – December 25, 1899) was an American army surgeon, historian, ornithologist, and author. He led surveys of the Arizona Territory, and later as secretary of the United States Geological and Geographical Survey of the Territories. He founded the American Ornithological Union in 1883, and was editor of its publication, '' The Auk''. Biography Coues was born in Portsmouth, New Hampshire, to Samuel Elliott Coues and Charlotte Haven Ladd Coues. He graduated at Columbian University, Washington, D.C., in 1861, and at the medical school of that institution in 1863. He served as a medical cadet in Washington in 1862–1863, and in 1864 was appointed assistant-surgeon in the regular army, and assigned to Fort Whipple, Arizona. While there was not yet any legal provision for divorce under its laws, the 1st Arizona State Legislature granted Coues an annulment of his marriage to Sarah A. Richardson. His marriage to Jeannie Augusta McKenney en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vireo
The vireos make up a family, Vireonidae, of small to medium-sized passerine birds found in the New World (Canada to Argentina, including Bermuda and the West Indies) and Southeast Asia. The family contains 62 species and is divided into eight genera. "Vireo" is a Latin word referring to a green migratory bird, perhaps the female golden oriole, possibly the European greenfinch. They are typically dull-plumaged and greenish in color, the smaller species resembling wood warblers apart from their heavier bills. They range in size from the Chocó vireo, dwarf vireo and lesser greenlet, all at around 10 cm and 8g, to the peppershrikes and shrike-vireos at up to 17 cm and 40g.Forshaw, Joseph & Parkes, Kenneth C. 1991. ''Encyclopaedia of Animals: Birds,'' p. 209. Merehurst Press, London. Distribution and habitat Most species are found in Middle America and northern South America. Thirteen species of true vireos occur farther north, in the United States, Bermuda an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Chihuahuan Desert
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a boo ...

Fauna Of The Sonoran Desert
The Sonoran Desert () is a hot desert and ecoregion in North America that covers the northwestern Mexican states of Sonora, Baja California, and Baja California Sur, as well as part of the Southwestern United States (in Arizona and California). It is the hottest desert in Mexico. It has an area of . In phytogeography, the Sonoran Desert is within the Sonoran floristic province of the Madrean region of southwestern North America, part of the Holarctic realm of the northern Western Hemisphere. The desert contains a variety of unique endemism, endemic plants and animals, notably, the saguaro (''Carnegiea gigantea'') and Stenocereus thurberi, organ pipe cactus (''Stenocereus thurberi''). The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin Desert, Great Basin, Mojave Desert, Mojave, and Chihuahuan Desert, Chihuahuan deserts) because it provides subtropical warmth in winter and two seasons of rainfall (in contrast, for example, to the Mojave's dry summers ...

Meso-American Wintering Birds
Mesoamerica is a historical region and cultural area that begins in the southern part of North America and extends to the Pacific coast of Central America, thus comprising the lands of central and southern Mexico, all of Belize, Guatemala, El Salvador, and parts of Honduras, Nicaragua and northwestern part of Costa Rica. As a cultural area, Mesoamerica is defined by a mosaic of cultural traits developed and shared by its indigenous cultures. In the pre-Columbian era, many indigenous societies flourished in Mesoamerica for more than 3,000 years before the Spanish colonization of the Americas began on Hispaniola in 1493. In world history, Mesoamerica was the site of two historical transformations: (i) primary urban generation, and (ii) the formation of New World cultures from the mixtures of the indigenous Mesoamerican peoples with the European, African, and Asian peoples who were introduced by the Spanish colonization of the Americas. Mesoamerica is one of the six areas in the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Birds Of Southwestern North America
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

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 New World warbler, 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 Pierre Vieillot. The type species was subsequently designated as the white-eyed vireo (''Vireo griseus'') by German ornithologist Hans Friedrich ...

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 Enlumin ...

Gnatcatcher
The gnatcatchers are a family of small passerine birds called ''Polioptilidae''. The 22 species occur in North and South America (except for the far south and the high Andean regions). Most species of this mainly tropical and subtropical group are resident, but the blue-grey gnatcatcher of the United States and southern Canada migrates south in winter. They are close relatives of the wrens.Atwood, J. & Lerman, S. (2006) Family Polioptilidae (Gnatcatchers). pp. 350–377 in: del Hoyo, J., A. Elliott, and D. Christie. eds (2006). ''Handbook of Birds of the World'' Vol. 11. Old World Flycatchers to Old World Warblers. Lynx Edicions, Barcelona. Description These dainty birds are intermediate between Old World warblers and wrens in their structure and habits, moving restlessly through foliage seeking insects. The gnatcatchers are mainly soft bluish grey in color, and have the typical insectivore's long sharp bill. Many species have distinctive black head patterns (especially ma ...
