Pinyon Jay
The pinyon jay (''Gymnorhinus cyanocephalus'') is a species of jay, and is the only member of the genus ''Gymnorhinus''. Native to Western North America, the species ranges from central Oregon to northern Baja California, and eastward as far as western Oklahoma, though wanderers are often sighted beyond this range. It is typically found within foothills, especially where pinyon pines (''Pinus edulis'' and ''Pinus monophylla'') occur. Description The pinyon jay is a bluish-grey coloured bird with deeper head colouring and whitish throat with black bill, legs and feet. Roughly intermediate between the blue jay and the Eurasian jay in size, its overall proportions are similar to Clark's nutcracker (''Nucifraga columbiana'') and this can be seen as convergent evolution, as both birds fill similar ecological niches. Taxonomy The pinyon jay was first collected, recorded, and first described as a species from a specimen shot along the Maria River in what is now northern Montana durin ...

Prince Maximilian Of Wied-Neuwied
Prince Alexander Philipp Maximilian zu Wied-Neuwied (23 September 1782 – 3 February 1867) was a German explorer, ethnologist and naturalist. He led a pioneering expedition to southeast Brazil between 1815–1817, from which the album ''Reise nach Brasilien,'' which first revealed to Europe real images of Brazilian Indians, was the ultimate result. It was translated into several languages and recognized as one of the greatest contributions to the knowledge of Brazil at the beginning of the nineteenth century. In 1832 he embarked on another expedition, this time to United States, together with the Swiss painter Karl Bodmer. Prince Maximilian collected many examples of ethnography, and many specimens of flora and fauna of the area, still preserved in museum collections, notably in the Lindenmuseum, Stuttgart. The genus '' Neuwiedia'' Blume (Orchidaceae) was named for him. Also, Prince Maximilian is honored in the scientific names of eight species of reptiles: '' Hydromedusa max ...

Lewis And Clark Expedition
The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the United States expedition to cross the newly acquired western portion of the country after the Louisiana Purchase. The Corps of Discovery was a select group of U.S. Army and civilian volunteers under the command of Captain Meriwether Lewis and his close friend Second Lieutenant William Clark. Clark and 30 members set out from Camp Dubois, Illinois, on May 14, 1804, met Lewis and ten other members of the group in St. Charles, Missouri, then went up the Missouri River. The expedition crossed the Continental Divide of the Americas near the Lemhi Pass, eventually coming to the Columbia River, and the Pacific Ocean in 1805. The return voyage began on March 23, 1806, at Fort Clatsop, Oregon, and ended on September 23 of the same year. President Thomas Jefferson commissioned the expedition shortly after the Louisiana Purchase in 1803 to explore and to map the newly acquired territory, to find a pr ...

Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...

Live Oak
Live oak or evergreen oak is any of a number of oaks in several different sections of the genus ''Quercus'' that share the characteristic of evergreen foliage. These oaks are not more closely related to each other than they are to other oaks. The name ''live oak'' comes from the fact that evergreen oaks remain green and "live" throughout winter, when other oaks are dormant and leafless. The name is used mainly in North America, where evergreen oaks are widespread in warmer areas along the Atlantic coast from southeast Virginia to Florida, west along the Gulf Coast to Louisiana and Mexico, and across the southwest to California. Evergreen oak species are also common in parts of southern Europe and south Asia, and are included in this list for the sake of completeness. These species, although not having "live" in their common names in their countries of origin, are colloquially called live oaks when cultivated in North America. When the term live oak is used in a specific rathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juniper
Junipers are coniferous trees and shrubs in the genus ''Juniperus'' () of the cypress family Cupressaceae. Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, throughout parts of West Asia, western, Central Asia, central and South Asia, southern Asia, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of in southeastern Tibet and the northern Himalayas, creating one of the highest tree lines on earth. Description Junipers vary in size and shape from tall trees, tall, to columnar or low-spreading shrubs with long, trailing branches. They are evergreen with needle-like and/or scale-like leaves. They can be either monoecious or dioecious. The female Conifer cone, seed cones are very distinctive, with fleshy, fruit-like coalescing scales which fuse together to form Juniper berry, a&n ...

Bird Colony
A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non- neornithine birds ( Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania. Variations on colonial nesting in birds Approximately 13% of all bird species nest colonially. Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonie ...

Bird Nest
A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests is known as ''caliology''. Not all bird species bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flock (birds)
A flock is a gathering of individual birds to forage or travel collectively. Avian flocks are typically associated with migration. Flocking also offers foraging benefits and protection from predators, although flocking can have costs for individual members. Flocks are often defined as groups consisting of individuals from the same species. However, mixed flocks consisting of two or more species are also common. Avian species that tend to flock together are typically similar in taxonomy and share morphological characteristics such as size and shape. Mixed flocks offer increased protection against predators, which is particularly important in closed habitats such as forests where early warning calls play a vital importance in the early recognition of danger. The result is the formation of many mixed-species feeding flocks. Mixed flocks While mixed flocks are typically thought to be composed of two different species, it is specifically the two different behaviours of the species ...

Pinyon–juniper Woodland
Pinyon–juniper woodland, also spelled piñon–juniper woodland, is a vegetation type (biome) of Western United States higher elevation deserts, characterized by being an open forest dominated by low, bushy, evergreen junipers (''Juniperus osteosperma,''Damian Fagan, Canyon Country Wildflowers, p. 3Pam MacKay, Mojave Desert Wildflowers, p19-20 ''Juniperus californica'',Karen Wiese, Sierra Nevada Wildflowers, 2013, p. 18 '' Juniperus grandis''), pinyon pines (''Pinus monophylla'', ''Pinus edulis''), and their associates which vary from region to region.Ronald J. Taylor, Sagebrush CountryLaird Blackwell, Great Basin Wildflowers, p5-6 The woodland's density and crown height varies dramatically depending on the site's soil and climate, the age of the stand, and the particular species present, with mature trees ranging in height from as low as 2 meters up to 15 meters. At lower elevations, junipers often predominate and trees are spaced widely, bordering on and mingling with grasslan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
