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 ...

Clinton Hart Merriam
Clinton Hart Merriam (December 5, 1855 – March 19, 1942) was an American zoologist, mammalogist, ornithologist, entomologist, ecologist, ethnographer, geographer, naturalist and physician. He was commonly known as the 'father of mammalogy', a branch of zoology referring to the study of mammals. Early life Clinton Hart Merriam was born in New York City in 1855 to Clinton Levi Merriam, a U.S. congressman, and Caroline Hart, a judge's daughter and a graduate of Rutgers Institute. The name Clinton, shared by both father and son, was in honor of New York governor DeWitt Clinton, whom the Merriam family had connections with. To avoid confusion, the younger Merriam went by his first initial combined with his middle name, his mother's maiden name, and thus often appears as C. Hart Merriam in both the literature of his time and thereafter. Although born in New York City, where his parents were staying the winter, the family home and place where Merriam spent his boyhood days was ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gliding (flight)
Gliding flight is heavier-than-air flight without the use of thrust; the term volplaning also refers to this mode of flight in animals. It is employed by gliding animals and by aircraft such as gliders. This mode of flight involves flying a significant distance horizontally compared to its descent and therefore can be distinguished from a mostly straight downward descent like with a round parachute. Although the human application of gliding flight usually refers to aircraft designed for this purpose, most powered aircraft are capable of gliding without engine power. As with sustained flight, gliding generally requires the application of an airfoil, such as the wings on aircraft or birds, or the gliding membrane of a gliding possum. However, gliding can be achieved with a flat ( uncambered) wing, as with a simple paper plane, or even with card-throwing. However, some aircraft with lifting bodies and animals such as the flying snake can achieve gliding flight without any wings b ...

Gopher
Pocket gophers, commonly referred to simply as gophers, are burrowing rodents of the family Geomyidae. The roughly 41 speciesSearch results for "Geomyidae" on thASM Mammal Diversity Database are all endemic to North and Central America. They are commonly known for their extensive tunneling activities and their ability to destroy farms and gardens. The name "pocket gopher" on its own may refer to any of a number of genera within the family Geomyidae. These are the "true" gophers, but several ground squirrels in the distantly related family Sciuridae are often called "gophers", as well. The origin of the word "gopher" is uncertain; the French ''gaufre'', meaning waffle, has been suggested, on account of the gopher tunnels resembling the honeycomb-like pattern of holes in a waffle; another suggestion is that the word is of Muskogean origin. Description Gophers weigh around , and are about in body length, with a tail long. A few species reach weights approaching . Within any sp ...

Peromyscus Maniculatus
''Peromyscus maniculatus'' is a rodent native to eastern North America. It is most commonly called the eastern deer mouse; when formerly grouped with the western deer mouse (''P. sonoriensis''), it was referred to as the North American deermouse and is fairly widespread across most of North America east of the Mississippi River, with the major exception being the lowland southeastern United States. Like other ''Peromyscus'' species, it can be a vector and carrier of emerging infectious diseases such as hantaviruses and Lyme disease. It is closely related to ''Peromyscus leucopus'', the white-footed mouse. Overview The species in its former broad sense had 61 subspecies, but some of these now belong to ''P. sonoriensis''. They are all tiny mammals that are plentiful in number. The deer mouse is a small rodent that lives in eastern North America and is closely related to the white-footed mouse, ''Peromyscus leucopus''.The New Encyclopædia Britannica. 2007. (Vol. 12, p. 631). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Red-backed Vole
The western red-backed vole (''Myodes californicus'') is a species of vole in the family Cricetidae. It is found in California and Oregon in the United States and lives mainly in coniferous forest. The body color is chestnut brown, or brown mixed with a considerable quantity of black hair gradually lightening on the sides and grading into a buffy-gray belly, with an indistinct reddish stripe on the back and a bicolored tail about half as long as the head and body. Taxonomy The western red-backed vole was initially described by C. Hart Merriam under its original scientific name ''Evotomys californicus''. The type specimen was obtained at near Eureka, California. It was an adult male collected by Theodore Sherman Palmer on June 3, 1889. Description The length of the western red-backed vole ranges from overall, with a tail between , hindfoot , and ear . The height ranges between 0.75–0.87 inches (18–21 mm).

Red Tree Vole
The red tree vole (''Arborimus longicaudus'') is a rodent of the Pacific Northwest, found in the US states of Oregon and California. They were formerly known as ''Phenacomys longicaudus'' and have also been called the red tree mouse. Description The red tree vole is a rodent in the family Cricetidae. It is found only in coastal forests of Oregon and northern California. They exclusively eat the needles of conifers, primarily Douglas-fir (''Pseudotsuga menziesii''), though they have occasionally been reported to eat the needles of Sitka spruce (''Picea sitchensis''). Red tree voles are about 6-8 in long, including the tail. When they are young, they exhibit a dull brown coat and develop a more reddish color with age. They are nocturnal and very difficult to see, but they can be detected by finding piles or wads of these resin ducts on the ground. Nesting and Home Range Red tree voles live almost exclusively in Douglas-fir trees, though they have occasionally been found in ...

Dusky-footed Woodrat
The dusky-footed woodrat (''Neotoma fuscipes'') is a species of nocturnal rodent in the family Cricetidae. They are commonly called "packrats" or "trade rats" and build large, domed dens that can reach several feet in height. Coyotes and other predators will attempt to prey on these rodents by laying waste to the dens, but the sheer volume of material is usually dissuasive. Occasionally, dusky-footed woodrats will build satellite dens in trees. Although these animals are solitary, except in the mating season (when they are most vulnerable to predation), dens are frequently found in clusters of up to several dozen, forming rough "communities". The mating system in this species appears to be variable, with promiscuity most generally at high population densities and monogamy at lower densities. They are similar in appearance to the common rat species ''Rattus rattus'' and ''Rattus norvegicus'', but with larger ears and eyes, softer coats, and furred tails. The California mouse, ...
