Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus Rattus. Other rat genera include Neotoma, Bandicota and Dipodomys.
Squirrels are members of the family Sciuridae, a family that includes small or medium-sized rodents. The squirrel family includes tree squirrels, ground squirrels, and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and dormice.
The brown rat, also known as the common rat, street rat, sewer rat, wharf rat, Hanover rat, Norway rat and Norwegian rat, is a widespread species of common rat. One of the largest muroids, it is a brown or grey rodent with a body length of up to 28 cm (11 in) long, and a tail slightly shorter than that. It weighs between 140 and 500 g. Thought to have originated in northern China and neighbouring areas, this rodent has now spread to all continents except Antarctica, and is the dominant rat in Europe and much of North America. With rare exceptions, the brown rat lives wherever humans live, particularly in urban areas.
The northern flying squirrel is one of three species of the genus Glaucomys, the only flying squirrels found in North America. They are found in coniferous and mixed coniferous forests across much of Canada, from Alaska to Nova Scotia, and south to the mountains of North Carolina and west to Utah in the United States. They are light brown with pale underparts and grow to a length of 25 to 37 cm. They are proficient gliders but uncoordinated walkers on the ground. They feed on a variety of plant material as well as tree sap, fungi, insects, carrion, bird eggs and nestlings. They mostly breed once a year in a cavity lined with lichen or other soft material. Except when they have young, they change nests frequently, and in winter a number of individuals may huddle together in a shared nest. Unlike most members of their family, flying squirrels are strictly nocturnal.
A rat king is a collection of rats or mice whose tails are intertwined and bound together in some way. This could be a result of an entangling material like hair, a sticky substance such as sap or gum, or the tails being tied together.
Richardson's ground squirrel, also known as the dakrat or flickertail, is a North American ground squirrel in the genus Urocitellus. Like a number of other ground squirrels, they are sometimes called prairie dogs or gophers, though the latter name belongs more strictly to the pocket gophers of family Geomyidae, and the former to members of the genus Cynomys.
The European water vole or northern water vole, is a semi-aquatic rodent. It is often informally called the water rat, though it only superficially resembles a true rat. Water voles have rounder noses than rats, deep brown fur, chubby faces and short fuzzy ears; unlike rats their tails, paws and ears are covered with hair.
The Spalacidae, or spalacids, are a family of rodents in the large and complex superfamily Muroidea. They are native to eastern Asia, the Horn of Africa, the Middle East, and southeastern Europe. It includes the blind mole-rats, bamboo rats, mole-rats, and zokors. This family represents the oldest split in the muroid superfamily, and comprises animals adapted to a subterranean way of life. These rodents were thought to have evolved adaptations to living underground independently until recent genetic studies demonstrated they form a monophyletic group. Members of the Spalacidae are often placed in the family Muridae along with all other members of the Muroidea.
Pale Male, or Palemale, was a red-tailed hawk that resided in and near New York City's Central Park from the 1990s until 2023. Birdwatcher and author Marie Winn gave him his name because of the unusually light coloring of his head. He was one of the first red-tailed hawks known to have nested on a building rather than in a tree and is known for establishing a dynasty of urban-dwelling red-tailed hawks.
The Laotian rock rat or kha-nyou, sometimes called the "rat-squirrel", is a species of rodent found in the Khammouan region of Laos. The species was first described in a 2005 article by Paulina Jenkins and coauthors, who considered the animal to be so distinct from all living rodents, they placed it in a new family, Laonastidae. It is in the monotypic genus Laonastes.
The domestication of small mammals to keep as pets is a relatively recent development, arising only after large-scale industrialization. Historically, Western society was more agrarian than today, with rodents as a whole seen as vermin that were carriers for disease and a threat to crops. Animals that hunted such pests, such as terriers and cats, were prized.
Edinburgh Zoo, formerly the Scottish National Zoological Park, is an 82-acre (33 ha) non-profit zoological park in the Corstorphine area of Edinburgh, Scotland.
The dassie rat is an African rodent found among rocky outcroppings. It is the only living member of its genus, Petromus, and family, Petromuridae. The name "dassie" means "hyrax" in Afrikaans, and the two animals are found in similar habitats. Petromus means "rock mouse" and dassie rats are one of many rodents sometimes called rock rats. The family and genus names are sometimes misspelled as Petromyidae and Petromys.
The Allegheny woodrat, is a species of "pack rat" in the genus Neotoma. Once believed to be a subspecies of the eastern woodrat, extensive DNA analysis has proven it to be a distinct species.
The golden-backed tree rat is a species of rodent in the family Muridae, found only in Australia.
Xeromys myoides, also known as the water mouse, marine mouse, mangrove mouse, false water rat, manngay and yirrkoo, is a species of rodent native to waterways of Australia and Papua New Guinea.
A pack rat or packrat, also called a woodrat or trade rat, are any species in the North and Central American rodent genus Neotoma. Pack rats have a rat-like appearance, with long tails, large ears, and large, black eyes. Pack rats are noticeably larger than deer mice, harvest mice, and grasshopper mice, and are usually somewhat larger than cotton rats.
Rodents are mammals of the order Rodentia, which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity.
Lost Land of the Volcano is a three-part nature documentary series produced by the BBC Natural History Unit which follows a scientific expedition to the island of New Guinea. The expedition team, which includes specialist zoologists, explorers and the BBC crew, travels to the extinct volcano of Mount Bosavi in central Papua New Guinea to document the biodiversity of this little-visited area and search for new species. At the time of filming, logging was taking place about 20 miles (32 km) south from the volcano, and one of expedition's aims was to find evidence to support the case to protect the area. Some members of the expedition team travelled to the island of New Britain several hundred kilometres to the east to chart an unexplored cave system and observe an active volcano.
Little Grey Rabbit is the lead character in a classic, eponymous series of English children's books, written by Alison Uttley and illustrated by Margaret Tempest, except for the last five, illustrated by Katherine Wigglesworth. They appeared over a forty-year period up to the mid-1970s to great acclaim, and gave rise to a TV series in 2000.
