Zumwalt Prairie
Zumwalt Prairie is a grassland area located in Wallowa County in northeast Oregon, United States. Measuring , much of the land is used for agriculture, with some portions protected as the Zumwalt Prairie Preserve owned by The Nature Conservancy.Richard, Terry. To conserve and protect (and hike). ''The Oregonian'', April 2, 2006. Part of that portion is designated as a National Natural Landmark. The high altitude prairie is along the west edge of Hells Canyon on the Oregon-Idaho border. Geography The Zumwalt Prairie grassland is situated on a basalt plateau which varies in elevation from and is dominated by several native bunchgrasses, including Idaho Fescue (''Festuca idahoensis''), Bluebunch wheatgrass (''Pseudoroegneria spicata''), Sandberg's Bluegrass (''Poa secunda'') and many species of wildflowers. The Zumwalt Prairie is a piece of a once extensive temperate grassland system west of the Rocky Mountains which extended into Canada. The Zumwalt Prairie grassland system re ...

Wallowa County, Oregon
Wallowa County () is the northeastern most county in the U.S. state of Oregon. As of the 2020 census, the population was 7,391, making it Oregon's fifth-least populous county. Its county seat is Enterprise. According to '' Oregon Geographic Names'', the origins of the county's name are uncertain, with the most likely explanation being it is derived from the Nez Perce term for a structure of stakes (a weir) used in fishing. An alternative explanation is that ''Wallowa'' is derived from a Nez Perce word for "winding water". The journals of Lewis and Clark Expedition record the name of the Wallowa River as ''Wil-le-wah''. Wallowa County is part of the eight-county definition of Eastern Oregon. History In 1871, the first white settlers came to the area, crossing the mountains in search of livestock feed in the Wallowa Valley. The county was established on February 11, 1887, from the eastern portion of Union County. Boundary changes occurred with Union County in 1890, 1900, and 191 ...

Pseudoroegneria Spicata
''Pseudoroegneria spicata'' is a species of grass known by the common name bluebunch wheatgrass. This native western North American perennial bunchgrass is also known by the scientific synonyms ''Elymus spicatus'' and ''Agropyron spicatum''. The grass can be found in the United States, Canada, and Mexico from Alaska and Yukon south as far as Sonora and Nuevo León. Description Bluebunch wheatgrass can grow up to three feet tall. It can often be distinguished from other bunchgrasses by the awns on its seedheads which stand out at an angle nearly 90 degrees from the stem. It is often bluish. The roots of the grass have a waxy layer that helps it resist desiccation in dry soils. In areas with more moisture the grass may produce rhizomes. The relationship between the traits and climates of ''P. spicata'' is consistent with those of other grass species that also have a summer growing season. Populations of ''P. spicata'' from warm, arid environments are often smaller with earlier phe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ammodramus Savannarum
The grasshopper sparrow (''Ammodramus savannarum'') is a small New World sparrow. It belongs to the genus ''Ammodramus,'' which contains three species that inhabit grasslands and prairies. Although sometimes found in crop fields and they will readily colonize reclaimed grassland. In the core of their range, grasshopper sparrows are dependent upon large areas of grassland where they avoid trees and shrubs. They seek out heterogenous patches of prairie that contain clumps of dead grass or other vegetation where they conceal their nest, and also contain barer ground where they forage for insects (especially grasshoppers), spiders, and seeds. Grasshopper sparrows are unusual among New World sparrows in that they sing two distinct song types, the prevalence of which varies with nesting cycle. The primary male song, a high trill preceded by a stereotyped series of short chips, is reminiscent of the sounds of grasshoppers and is the origin of this species' name. Like some other birds of t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Eremophila Alpestris
The horned lark or shore lark (''Eremophila alpestris'') is a species of lark in the family Alaudidae found across the northern hemisphere. It is known as "horned lark" in North America and "shore lark" in Europe. Taxonomy, evolution and systematics The specific ''alpestris'' is Latin and means "of the high mountains", from ''Alpes'', the Alps. The horned lark was originally classified in the genus ''Alauda''. The horned lark is suggested to have diverged from Temminck's lark (''E. bilopha'') around the Early-Middle Pleistocene, according to genomic divergence estimates. The horned lark is known from around a dozen localities of Late Pleistocene age, including those in Italy, Russia, The United Kingdom and the United States. The earliest known fossil is from the Calabrian (stage), Calabrian of Spain, around 1–0.8 million years old. In 2020, a 46,000 year old frozen specimen was described from the Russian Far East. Recent genetic analysis has suggested that the species consist ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pooecetes Gramineus
The vesper sparrow (''Pooecetes gramineus'') is a medium-sized New World sparrow. It is the only member of the genus ''Pooecetes''. Taxonomy The Vesper Sparrow is believed to be most closely related to the Lark sparrow. It is the only species in the genus ''Pooecetes'', meaning grass dweller. Description Adults have light brown upper-parts and light under-parts, both with darker streaking. There are three features that are unique to the Vesper Sparrow. The first is the presence of a small, white ring surrounding the eyes. The second is the flash of white tail feathers that occurs during flight. The third is the presence of a chestnut patch on the shoulder. However, this is usually not visible to an observer. Another notable characteristic is that some Sparrows, especially west of the Cascades, tend to have a more pinkish hue. They also do not have a bold eyeline found in some sparrows. Measurements: * Length: 5.1-6.3 in (13-16 cm) * Weight: 0.7-1.0 oz (20-28 g) * Wing ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Passerculus Sandwichensis
The Savannah sparrow (''Passerculus sandwichensis'') is a small New World sparrow. It was the only member of the genus '' Passerculus'' and is typically the only widely accepted member. Comparison of mtDNA NADH dehydrogenase subunit 2 and 3 sequences indicates that the Ipswich sparrow, formerly usually considered a valid species (as ''Passerculus princeps''), is a well-marked subspecies of the Savannah sparrow, whereas the southwestern large-billed sparrow should be recognized as a distinct species (''Passerculus rostratus''). The species name ''sandwichensis'' is Latin, of place, Sandwich, Unalaska, or Aleutians area, from which came the first subspecies, Aleutian Savannah sparrow, to be described. The common name honors Savannah, Georgia where Alexander Wilson discovered the species in 1811. Distribution This passerine bird breeds in Alaska, Canada, northern, central and Pacific coastal United States, Mexico and Guatemala. The Pacific and Mexican breeders are resident, but o ...

Aquila Chrysaetos
The golden eagle (''Aquila chrysaetos'') is a bird of prey living in the Northern Hemisphere. It is the most widely distributed species of eagle. Like all eagles, it belongs to the family Accipitridae. They are one of the best-known birds of prey in the Northern Hemisphere. These birds are dark brown, with lighter golden-brown plumage on their napes. Immature eagles of this species typically have white on the tail and often have white markings on the wings. Golden eagles use their agility and speed combined with powerful feet and large, sharp talons to hunt a variety of prey, mainly hares, rabbits, and marmots and other ground squirrels. Golden eagles maintain home ranges or territories that may be as large as . They build large nests in cliffs and other high places to which they may return for several breeding years. Most breeding activities take place in the spring; they are monogamous and may remain together for several years or possibly for life. Females lay up to four e ...

Buteo Jamaicensis
The red-tailed hawk (''Buteo jamaicensis'') is a bird of prey that breeds throughout most of North America, from the interior of Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the most common members within the genus of ''Buteo'' in North America or worldwide. The red-tailed hawk is one of three species colloquially known in the United States as the " chickenhawk", though it rarely preys on standard-sized chickens. The bird is sometimes also referred to as the red-tail for short, when the meaning is clear in context. Red-tailed hawks can acclimate to all the biomes within their range, occurring on the edges of non-ideal habitats such as dense forests and sandy deserts.Preston, C. R. (2000). ''Red-tailed Hawk''. Stackpole Books. The red-tailed hawk occupies a wide range of habitats and altitudes, including deserts, grasslands (from small meadows to the treed fringes of more extensive prairies), coniferous and deciduous forests, agricultur ...

Buteo Lagopus
The rough-legged buzzard or rough-legged hawk (''Buteo lagopus'') is a medium-large bird of prey. It is found in Arctic and Subarctic regions of North America, Europe, and Russia during the breeding season and migrates south for the winter. It was traditionally also known as the rough-legged falcon in such works as John James Audubon's ''The Birds of America''. Nests are typically located on cliffs, bluffs or in trees. Clutch sizes are variable with food availability, but three to five eggs are usually laid. These hawks hunt over open land, feeding primarily on small mammals. Along with the kestrels, kites, and osprey, this is one of the few birds of prey to hover regularly. Description This fairly large raptorial species is with wingspan ranging from . Individuals can weigh from with females typically being larger and heavier than males. Weights appear to increase from summer to winter in adults, going from an average of in males and from in females. Among the members of t ...

Buteo Swainsoni
Swainson's hawk (''Buteo swainsoni'') is a large bird species in the Accipitriformes order. This species was named after William Swainson, a British naturalist. It is colloquially known as the grasshopper hawk or locust hawk, as it is very fond of Acrididae (locusts and grasshoppers) and will voraciously eat these insects whenever they are available. Their breeding habitat is prairie and dry grasslands in western North America. They build a stick nest in a tree or shrub or on a cliff edge. This species is a long-distance migrant, wintering in Argentina; it has been recorded as a vagrant in neighboring Chile, in the island countries of the Dominican Republic, and Trinidad and Tobago, and in Norway. This species or its immediate predecessor is the ancestor of the Galápagos hawk, as demonstrated by recent research. Then later diverged from the mainland birds perhaps 300,000 years ago, a very short time in evolution. Description Swainson's hawk is a raptor and a medium-sized mem ...
