WThe little brown bat or little brown myotis is a species of mouse-eared microbat found in North America. It has a small body size and glossy brown fur. It is similar in appearance to several other mouse-eared bats, including the Indiana bat, northern long-eared bat, and Arizona myotis, to which it is closely related. Despite its name, the little brown bat is not closely related to the big brown bat, which belongs to a different genus.
WThe California myotis is a species of vesper bat. It is found in British Columbia in Canada, Guatemala, Mexico, and in the western United States, including California.
WThe eastern red bat is a species of microbat in the family Vespertilionidae. Eastern red bats are widespread across eastern North America, with additional records in Bermuda.
WThe eastern small-footed bat is a species of vesper bat. It can be found in southern Ontario and Quebec in Canada and in mountainous portions of the eastern United States from New England to northern Georgia, and westward to northern Arkansas. It is among the smallest bats in eastern North America and is known for its small feet and black face-mask. Until recently, all North American small-footed Myotis were considered to be "Myotis leibii". The western population is now considered to be a separate species, Myotis ciliolabrum. The Eastern small-footed bat is rare throughout its range, although the species may be locally abundant where suitable habitat exists. Studies suggest white-nose syndrome has caused declines in their populations. However, most occurrences of this species have only been counted within the past decade or two and are not revisited regularly, making their population status difficult to assess. Additionally, most bat populations in the Eastern U.S. have been monitored using surveys conducted in caves and mines in the winter, but Eastern small-footed bats hibernate in places that make them unlikely to be encountered during these surveys. Perhaps as a result, the numbers of Eastern small-footed bats counted in winter tend to be low and they are relatively variable compared to other species of bats. Many biologists believe the species is stable, having declined little in recent times, but that it is vulnerable due to its relatively restricted geographic range and habitat needs.
WThe fringed myotis is a species of vesper bat that is found in British Columbia in Canada, Mexico, and the western United States.
WThe hoary bat is a species of bat in the vesper bat family, Vespertilionidae. It lives throughout most of North America and much of South America, with disjunct populations in the Galápagos Islands and Hawaii.
WKeen's myotis is a species of vesper bat. It is found in British Columbia in Canada and in Washington and Alaska in the United States. It is named after the Rev. John Henry Keen, who collected the specimen that formed the basis for the first scientific description of the species. Classification for Keen's myotis formerly included the Northern long-eared Myotis, resulting in older studies confusing the species for one another.
WThe long-eared myotis is a species of vesper bat in the suborder Microchiroptera. It can be found in western Canada, the western United States, and Baja California in Mexico.
WThe long-legged myotis is a species of vesper bat that can be found in western Canada, Mexico, and the western United States.
WMyotis septentrionalis, the northern long-eared bat or northern myotis, is a species of bat native to North America. There are no recognised subspecies. The northern long-eared bat is about 3–3.7 inches in length, with a wingspan of 9–10 inches. It is distinguishable by its long ears when comparing it to other bats in its genus. This species is commonly found in the northern United States and Southern Canada east of British Columbia. The geographic range includes 37 states.
WThe pallid bat is a species of bat that ranges from western Canada to central Mexico. It is the sole species of its genus and is closely related to Van Gelder's bat, which is sometimes included in Antrozous. Although it has in the past been placed in its own subfamily (Antrozoinae) or even family (Antrozoidae), it is now considered part of the subfamily Vespertilioninae and the tribe Antrozoini.
WThe silver-haired bat is a solitary migratory species of vesper bat in the family Vespertilionidae and the only member of the genus Lasionycteris.
WThe spotted bat is a species of vesper bat and the only species of the genus Euderma.
WTownsend's big-eared bat is a species of vesper bat.
WThe tricolored bat is a species of microbat native to eastern North America. Formerly known as the eastern pipistrelle, based on the errant belief that it was closely related to European Pipistrellus species, the closest known relative of the tricolored bat is now recognized as the canyon bat. Its common name "tricolored bat" derives from the coloration of the hairs on its back, which have three distinct color bands. It is the smallest bat species in the eastern and midwestern US, with individuals weighing only 4.6–7.9 g (0.16–0.28 oz). This species mates in the fall before hibernation, though due to sperm storage, females do not become pregnant until the spring. Young are born helpless, though rapidly develop, flying and foraging for themselves by four weeks old. It has a relatively long lifespan, and can live nearly fifteen years.
WThe western small-footed bat, also known as the western small-footed myotis, is a species of vesper bat native to North America.
