List Of Oregon Birds
This list of Oregon birds lists wild bird species found in the U.S. state of Oregon and accepted by the Oregon Bird Records Committee (OBRC). As of August 2022, there are 547 species on the list. Of them, 164 are on the review list (see below). Nine species were introduced to Oregon or elsewhere in North America; one of them and two others have been extirpated from the state. Bird counts often change depending on factors such as the number and training of the observers, as well as opinions about what constitutes an officially recognized subspecies. Though northern climes typically do not support as many species as southerly locations, Oregon is fifth in bird species diversity in the United States, behind Florida, New Mexico, Texas and California. This amount of diversity is attributable to Oregon's numerous distinctive ecoregions and relatively mild winter weather, which make it an important wintering ground for migratory bird species, especially waterfowl, on the Pacific Flyw ...

Western Meadowlark
The western meadowlark (''Sturnella neglecta'') is a medium-sized icterid bird, about in length. It nests on the ground in open grasslands across western and central North America. It feeds mostly on bugs, but will also feed on seeds and berries. The western meadowlark has distinctive calls described as watery or flute-like, which distinguish it from the closely related eastern meadowlark. The western meadowlark is the state bird of six states: Montana, Kansas, Nebraska, North Dakota, Oregon, and Wyoming. Taxonomy The western meadowlark was formally described in 1844 by the American ornithologist John James Audubon under its current binomial name ''Sturnella neglecta''. The specific epithet is from the Latin ''neglectus'' meaning "ignored", "overlooked", "neglected" or "disregarded". Audubon explained that although the account of the Lewis and Clark Expedition of 1803–1806 mentioned yellow larks, these had never been formally described. The type locality is Old Fort Un ...

Taxonomic Sequence
Taxonomic sequence (also known as systematic, phyletic or taxonomic order) is a sequence followed in listing of taxa which aids ease of use and roughly reflects the evolutionary relationships among the taxa. Taxonomic sequences can exist for taxa within any rank, that is, a list of families, genera, species can each have a sequence. Early biologists used the concept of "age" or "primitiveness" of the groups in question to derive an order of arrangement, with "older" or more "primitive" groups being listed first and more recent or "advanced" ones last. A modern understanding of evolutionary biology has brought about a more robust framework for the taxonomic ordering of lists. A list may be seen as a rough one-dimensional representation of a phylogenetic tree. Taxonomic sequences are essentially heuristic devices that help in arrangements of linear systems such as books and information retrieval systems. Since phylogenetic relationships are complex and non-linear, there is no unique ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Snowy Plover
The snowy plover (''Charadrius nivosus'') is a small wader in the plover bird family, typically about 5-7" in length. It breeds in the southern and western United States, the Caribbean, Ecuador, Peru, and Chile. Long considered to be a subspecies of the Kentish plover, it is now known to be a distinct species. Parts of or entire beaches along the Central California coast are protected as nesting sites for the snowy plover and completely restricted to humans. UC Santa Barbara and the Vandenberg Space Force Base are two organizations leading the effort for beaches near them. Description Measurements: * Length: 5.9-6.7 in (15-17 cm) * Weight: 1.1-2.0 oz (32.5-58 g) * Wingspan: 13.4-17.0 in (34-43.2 cm) Taxonomy Genetic research published in 2009 strongly suggested that the snowy plover is a separate species from the Kentish plover, and by July, 2011, the International Ornithological Congress (IOC), and the American Ornithologists' Union (AOU) North American committee h ...

Northern Spotted Owl
The northern spotted owl (''Strix occidentalis caurina'') is one of three spotted owl subspecies. A western North American bird in the family Strigidae, genus ''Strix (genus), Strix'', it is a medium-sized dark brown owl native to the Pacific Northwest. An important Bioindicator, indicator species, the northern spotted owl remains Threatened species, threatened due to continued population decline from human-caused habitat destruction and competition with invasive species, its main competitor being the barred owl. Description Northern spotted owls have dark brown plumage with white spots and no ear tufts. They are typically around sixteen to nineteen inches in length and one to one and one sixth pounds. Females are about 10-20% larger than males. Their wingspan is approximately 42 inches. They are a mainly nocturnal species, and form long-term pair bonds. While most owls have yellow to red-orange colored eyes, northern spotted owls are one of the few owls with darkish to black-c ...

Oregon Coast
The Oregon Coast is a coastal region of the U.S. state of Oregon. It is bordered by the Pacific Ocean to its west and the Oregon Coast Range to the east, and stretches approximately from the California state border in the south to the Columbia River in the north. The region is not a specific geological, environmental, or political entity, and includes the Columbia River Estuary. The Oregon Beach Bill of 1967 allows free beach access to everyone. In return for a pedestrian easement and relief from construction, the bill eliminates property taxes on private beach land and allows its owners to retain certain beach land rights. Traditionally, the Oregon Coast is regarded as three distinct sub–regions: * The North Coast, which stretches from the Columbia River to Cascade Head. * The Central Coast, which stretches from Cascade Head to Reedsport. * The South Coast, which stretches from Reedsport to the Oregon–California border. The largest city is Coos Bay, population 16,700 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon Islands National Wildlife Refuge
Oregon Islands National Wildlife Refuge is a U.S. National Wildlife Refuge off the southwestern Oregon Coast. It is one of six National Wildlife Refuges comprising the Oregon Coast National Wildlife Refuge Complex. The Oregon Islands provides wilderness protection to 1,853 small islands, rocks, and reefs plus two headlands, totaling spanning of Oregon's coastline from the Oregon–California border to Tillamook Head. There are sites in six of the seven coastal counties of Oregon. From north to south they are Clatsop, Tillamook, Lincoln, Lane, Coos, and Curry counties. ( Douglas County is the only coastal Oregon county not included in the refuge.) The area is managed by the United States Fish and Wildlife Service. History The Oregon Islands National Wildlife Refuge was created in 1935 by the federal government. Haystack Rock off Cannon Beach was added to the refuge in 1968, which became a wilderness area in 1978. The first mainland addition to the refuge came in 1991 when Coqu ...

Christmas Bird Count
The Christmas Bird Count (CBC) is a census of birds in the Western Hemisphere, performed annually in the early Northern-hemisphere winter by volunteer birdwatchers and administered by the National Audubon Society. The purpose is to provide population data for use in science, especially conservation biology, though many people participate for recreation. The CBC is the longest-running citizen science survey in the world. History Up through the 19th century, many North Americans participated in the tradition of Christmas "side hunts", in which they competed at how many birds they could kill, regardless of whether they had any use for the carcasses and of whether the birds were beneficial, beautiful, or rare. In December 1900, the U.S. ornithologist Frank Chapman, founder of Bird-Lore (which became Audubon magazine), proposed counting birds on Christmas instead of killing them. On Christmas Day of that year, 27 observers took part in the first count in 25 places in the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
