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. They have a round facial disc that is dark brown with a visible "X" between their eyes. Females are about 10-20% larger than males. Their wingspan is approximately 42 inches.

Clinton Hart Merriam
Clinton Hart Merriam (December 5, 1855 – March 19, 1942) was an American zoologist, mammalogist, ornithologist, entomologist, ecologist, ethnographer, geographer, natural history, 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 University, 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 Mer ...

Pacific
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

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 , 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 Pocket gophers weigh around , and are about in body length, with a tail long. A few species reach weights approaching . Within any p ...

Peromyscus Maniculatus
''Peromyscus maniculatus'', the eastern deermouse, is a rodent native to eastern North America. It is a species of the genus ''Peromyscus'', a closely related group of New World rats and mice, New World mice often called "deermice". When formerly grouped with the western deermouse (''P. sonoriensis''), it was once referred to as the North American deermouse, a species which is no longer recognized. It is fairly widespread across most of North America east of the Mississippi River, with the major exception being the lowland southeastern United States. Like certain other ''Peromyscus'' species, it can be a vector (epidemiology), vector and asymptomatic carrier, 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 numb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Red-backed Vole
The western red-backed vole (''Clethrionomys 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 . The species is closely related to the southern red-backed vole (''Clethrionomys gapperi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 feed exclusively on the needles of conifers, primarily Douglas-fir (''Pseudotsuga menziesii''), though they occasionally eat the needles of western hemlock (''Tsuga heterophylla''), Sitka spruce (''Picea sitchensis''), grand fir (''Abies grandis''), and Bishop pine (''Pinus muricata''). 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 resin ducts (see below) on the ground. Nesting and home range Red tree ...

Bushy-tailed Woodrat
The bushy-tailed woodrat, or packrat (''Neotoma cinerea'') is a species of rodent in the family Cricetidae found in Canada and the United States. Its natural habitats are boreal forests, temperate forests, dry savanna, temperate shrubland, and temperate grassland. The bushy-tailed woodrat is the original "pack rat", the species in which the trading habit is most pronounced. It has a strong preference for shiny objects and will drop whatever it may be carrying in favor of a coin or a spoon. Description Bushy-tailed woodrats can be identified by their large, rounded ears, and their long, bushy tails. They are usually brown, peppered with black hairs above with white undersides and feet. The top coloration may vary from buff to almost black. The tail is squirrel-like - bushy, and flattened from base to tip. These woodrats are good climbers and have sharp claws. They use their long tails for balance while climbing and jumping, and for added warmth. These rodents are sexually dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dusky-footed Woodrat
The dusky-footed woodrat (''Neotoma fuscipes'') is a species of nocturnal rodent in the family Cricetidae. Nicknames include "packrats" or "trade rats" because of their tendency to hoard things, build large domed dens, and "trade" by dropping then picking up another object for it. 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 ...
