Barred Owl
The barred owl (''Strix varia''), also known as the northern barred owl, striped owl or, more informally, hoot owl, is a North American large species of owl. A member of the true owl family, Strigidae, they belong to the genus '' Strix'', which is also the origin of the family's name under Linnaean taxonomy.Sclater, P. L. (1879). ''Remarks on the Nomenclature of the British Owls, and on the Arrangement of the Order Striges''. Ibis, 21(3), 346-352. Barred owls are largely native to eastern North America, but have expanded their range to the west coast of North America where they are considered invasive.Evers, L. (2014).

Benjamin Smith Barton
Benjamin Smith Barton (February 10, 1766 – December 19, 1815) was an American botanist, naturalist, and physician. He was one of the first professors of natural history in the United States and built the largest collection of botanical specimens in the country. He wrote the first American textbook on botany. Early life Barton's father, Rev. Thomas Barton, was an Irish immigrant from Carrickmacross who opened a school near Norristown, Pennsylvania in 1751. His mother was Esther Rittenhouse, sister of astronomer David Rittenhouse. Between 1780 and 1782, Barton studied at York Academy in Lancaster, Pennsylvania, where he showed an aptitude for drawing and an interest in collecting natural history specimens. Two years later, he attended the College of Philadelphia School of Medicine, studied medicine under Thomas Shippen, and attended Benjamin Rush's lectures in 1785. Young Barton also accompanied his uncle, David Rittenhouse, who had been commissioned to survey the western boun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spotted Owl
The spotted owl (''Strix occidentalis'') is a species of true owl. It is a resident species of old-growth forests in western North America, where it nests in tree hollows, old bird of prey nests, or rock crevices. Nests can be between high and usually contain two eggs (though some contain as many as four). It is a nocturnal owl which feeds on small mammals and birds. Three subspecies are recognized, ranging in distribution from British Columbia to Mexico. The spotted owl is under pressure from habitat destruction throughout its range, and is currently classified as a near-threatened species. Description The spotted owl has an average length of , wingspan of , and weight of . Its eggs are a little over long, and are white and smooth with a slightly grainy texture. The spotted owl is similar in appearance to the barred owl, but has cross-shaped markings on the underparts, whereas the barred owl is alternately barred on the breast and streaked on the belly. Barred owls are larger a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tibiotarsus
The tibiotarsus is the large bone between the femur and the tarsometatarsus in the leg of a bird. It is the fusion of the proximal part of the tarsus with the tibia. A similar structure also occurred in the Mesozoic Heterodontosauridae. These small ornithischian dinosaurs were unrelated to birds and the similarity of their foot bones is best explained by convergent evolution. See also *Bird anatomy References * Proctor, Nobel S.

Carolinas
The Carolinas are the U.S. states of North Carolina and South Carolina, considered collectively. They are bordered by Virginia to the north, Tennessee to the west, and Georgia to the southwest. The Atlantic Ocean is to the east. Combining North Carolina's population of 10,439,388 and South Carolina's of 5,118,425, the Carolinas have a collective population of 15,557,813 as of 2020. If the Carolinas were a single state of the United States, it would be the fifth-most populous state, behind California, Texas, Florida, and New York. The Carolinas were known as the Province of Carolina during America's early colonial period, from 1663 to 1710. Prior to that, the land was considered part of the Colony and Dominion of Virginia, from 1609 to 1663. The province, named ''Carolina'' to honor King Charles I of England, was divided into two royal colonies in 1729, although the actual date is the subject of debate.

Upper Midwest
The Upper Midwest is a region in the northern portion of the U.S. Census Bureau's Midwestern United States. It is largely a sub-region of the Midwest. Although the exact boundaries are not uniformly agreed-upon, the region is defined as referring to the states of Michigan, Minnesota and Wisconsin; some definitions include Iowa, North Dakota and South Dakota as well. Definitions The National Weather Service defines its Upper Midwest as the states of Iowa, Michigan, Minnesota, North Dakota, South Dakota and Wisconsin. The United States Geological Survey uses two different Upper Midwest regions: *The USGS Upper Midwest Environmental Sciences Center considers it to be the six states of Illinois, Indiana, Iowa, Michigan, Minnesota and Wisconsin, which comprise the watersheds of the Upper Mississippi River and upper Great Lakes. *The USGS Mineral Resources Program considers the area to contain Illinois, Indiana, Michigan, Minnesota and Wisconsin.

Northeastern United States
The Northeastern United States, also referred to as the Northeast, the East Coast, or the American Northeast, is a geographic region of the United States. It is located on the Atlantic coast of North America, with Canada to its north, the Southern United States to its south, and the Midwestern United States to its west.

Oraristrix
The La Brea owl (''Oraristix brea'') is an extinct owl reported from the upper Pleistocene asphalt deposits of the La Brea Tar Pits in Los Angeles, California. It was first described in 1933 by Hildegarde Howard as ''Strix brea'', but this extinct owl was recently placed into its own genus by Campbell and Bocheński (2010). The Brea owl has also been found in the upper Pleistocene asphalt deposits of Carpinteria, California. ''Oraristrix brea'' is interpreted as more terrestrial in habits than forest owls because, compared to North American species of ''Bubo'' and ''Strix'', it had longer legs relative to its wingspan. See also *'' Glaucidium kurochkini'', a pygmy owl also known from the La Brea Tar Pits *'' Asphaltoglaux'', another owl from the La Brea Tar Pits, this one being more closely related to owls of the genus ''Aegolius ''Aegolius'' is a genus of small true owls.

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
