Little Brown Bat
The little brown bat or little brown myotis (''Myotis lucifugus'') is an endangered 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. Its mating system is polygynandrous, or promiscuous, and females give birth to one offspring annually. The offspring, called pups, are quickly weaned and reach adult size in some dimensions by three weeks old. The little brown bat has a mean lifespan of 6.5 years, though one individual in the wild reached 34 years old. It is nocturnal, foraging for its insect prey at night and roosting in hollow trees or buildings during the day, among less common roost types. It navigates and locates prey with echolocatio ...

John Eatton Le Conte
John Eatton Le Conte, Jr. (sometimes John Eatton LeConte or John Eaton Leconte) (February 22, 1784 – November 21, 1860) was an American naturalist. He was born near Shrewsbury, New Jersey, the son of John Eatton Le Conte and Jane Sloane Le Conte. He graduated from Columbia College, where he showed an interest in science and was taught natural history by David Hosack, founder of Elgin Botanical Garden. John Le Conte's older brother Louis inherited the family plantation, Woodmanston, near Midway in Georgia. Although John Le Conte usually lived in New York or New England, he spent his winters at Woodmanston. He suffered from rheumatism, and possibly other ailments, for most of his adult life. In April 1818 Le Conte was appointed captain in the United States Army Corps of Topographical Engineers. His early assignments included surveying the vicinity of Norfolk, Virginia, the harbor at Savannah, Georgia and Ossabaw Sound, Georgia. LeConte was promoted to brevet major in ...

White-nose Syndrome
White-nose syndrome (WNS) is a fungal disease in North American bats which has resulted in the dramatic decrease of the bat population in the United States and Canada, reportedly killing millions as of 2018. The condition is named for a distinctive fungal growth around the muzzles and on the wings of hibernating bats. It was first identified from a February 2006 photo taken in a cave located in Schoharie County, New York. The syndrome has rapidly spread since then. In early 2018, it was identified in 33 U.S. states and seven Canadian provinces; plus the fungus, albeit sans syndrome, had been found in three additional states. Most cases are in the eastern half of both countries, but in March 2016, it was confirmed in a little brown bat in Washington state. In 2019, evidence of the fungus was detected in California for the first time, although no affected bats were found. The disease is caused by the fungus ''Pseudogymnoascus destructans'', which colonizes the bat's skin. No obvious ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myotis Evotis
The long-eared myotis (''Myotis evotis'') 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. Description The long-eared myotis is a pale brown or straw-colored bat with black ears and wing membranes. The face is black in color as well. Specimens found along the coast are generally darker in coloration and are considered to be part of the subspecies ''Myotis evotis pacificus.'' Range and distribution The range of the long-eared myotis includes several different environments. It has been known to occur in semiarid shrublands, shortgrass prairie, and subalpine forests, with habitats ranging from sea level to . They roost in a variety of places, including tree cavities, rock crevices, caves, and even abandoned buildings. They seem to prefer rock crevices, while individuals in the northern part of the range favor ponderosa and lodgepole pines. Reproducing females generally roost ...

Myotis Thysanodes
The fringed myotis (''Myotis thysanodes'') is a species of vesper bat that is found in British Columbia, Mexico, and the western United States. Description ''Myotis thysanodes,'' or the fringed myotis, has the shortest ears of the long-eared myotis group. The fringed myotis gets its name from the distinct fringe of short, wire-like hairs found on the membrane between its hind legs. With a lifespan that can reach upwards of 18 years, this species has an average total body length of roughly 85mm and an average weight of 8.8 grams.Schmidly, D. 1991. ''Bats of Texas''. College Station:Texas A&M University Press. Ear length is about 16.5mm and they project roughly 5mm beyond its snout. Sexual dimorphism is seen in this species with males being much smaller than their female counterparts. They possess a pelage that is full and tends to be light yellow-brown or olive on the back with an off-white color on its underside. Northern populations tend to have darker coloration.

Myotis Occultus
The Arizona myotis (''Myotis occultus'') is a vesper bat species inhabiting much of the southwestern United States and central Mexico as far south as the Distrito Federal. Taxonomy and etymology It was described as a new species in 1909 by American zoologist Ned Hollister. The holotype was collected near Needles, California, in 1905. Its specific name "''occultus''" is Latin for "hidden or concealed". Description It is a small species with a total length of — of the total length, consists of its tail. Its fur is glossy brown with a cinnamon tint. The ventral fur and its face are paler brown. Range and habitat Its range includes parts of the Southwestern United States and the Mexican state of Chihuahua. It is found in a range of elevations from near sea level to above sea level.

Myotis Volans
The long-legged myotis (''Myotis volans'') is a species of vesper bat that can be found in western Canada, Mexico, and the western United States. Description ''Myotis volans'' is a species of bat found in Order Chiroptera, Family Vespertillionidae. They are closely related to ''Myotis lucifugus'' (little brown bat) and ''Myotis thysanodes'' (fringe-tailed bat). Three sub-species have been identified. They are the second largest myotis species found in the western United States. They have a wingspan of 10-12 inches and an average body mass of 7.5 grams. ''Myotis volans'' is also known as the long-legged myotis due to their longer tibia length compared to other myotis species. Their pelage is light brown to chocolate brown or reddish brown and they have short, rounded ears. When their ears are pushed toward their nose, the tips of their ears just reach their nostrils. Their most distinguishing characteristic is that they have fur on the underside of the wings that extends f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myotis Sodalis
The Indiana bat (''Myotis sodalis'') is a medium-sized mouse-eared bat native to North America. It lives primarily in Southern and Midwestern U.S. states and is listed as an endangered species. The Indiana bat is grey, black, or chestnut in color and is 1.2–2.0 in long and weighs 4.5–9.5 g (0.16–0.34 oz). It is similar in appearance to the more common little brown bat, but is distinguished by its feet size, toe hair length, pink lips, and a keel on the calcar. Indiana bats live in hardwood and hardwood-pine forests. It is common in old-growth forest and in agricultural land, mainly in forest, crop fields, and grasslands. As an insectivore, the bat eats both terrestrial and aquatic flying insects, such as moths, beetles, mosquitoes, and midges. The Indiana bat is listed as an endangered species by the U.S. Fish and Wildlife Service. It has had serious population decline, estimated to be more than 50% over the past 10 years, based on direct observation and a declin ...

Myotis Auriculus
The southwestern myotis (''Myotis auriculus'') is a species of vesper bat. It is found in Guatemala, Mexico, and in Arizona and New Mexico in the United States. Taxonomy The southwestern myotis is a member of the order Chiroptera and the family Vespertilionidae. Discovered in 1955 by Baker and Stains, it was originally believed to be a member of the species ''Myotis evotis''. Both bats live in the same region and occupy similar niches. Later that same year Hoffmeister and Krutzsch identified the mysterious bat as ''M. evotis Apache'', a new subspecies. ''M. e. Apache'' was changed to ''M. e. auriculus'' in 1959 by Hall and Kelson. In 1960 it was determined that the southwestern myotis was, in fact, not a member of ''M. evotis'' but a member of ''M. keenii''. This determination was made by a scientist named Findley. It wasn't until 1969 that ''M. auriculus'' was recognized as an independent species by scientists Genoways and Jones. ''M. auriculus'' and ''M. evotis'' exhibit diffe ...

Myotis Septentrionalis
''Myotis septentrionalis'', known as the northern long-eared bat or northern myotis, is a species of bat native to North America. There are no recognized 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. Description The northern long-eared bat is a small bat, measuring an average of in total length, including a tail about long. Adults weigh between . The fur and wing membranes are light brown in color, and the bat lacks the dark shoulder spots found in the closely related, and otherwise similar Keen's myotis (''Myotis keenii''). Compared to other ''Myotis'' species, these bats have long ears with a relatively long, pointed tragus; when folded forwards the ears extend well past the nose. Th ...

Myotis Leibii
The eastern small-footed bat (''Myotis leibii'') 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myotis Californicus
The California myotis (''Myotis californicus'') is a species of vesper bat. It is found in British Columbia in Canada, Guatemala, Mexico, and in the western United States, including California. Description The California myotis is a small (70–94mm and 3.3–5.4g) bat with pale, dull fur. Ears are of medium (12–15mm) size, with a narrow, pointed tragus (ear). They have an obviously keeled calcar and very small feet (5–7mm), smaller even than the feet of the western small-footed myotis, for which they are easily confused. Other distinguishing features include the slightly lighter face mask and shorter appearance of the California myotis' tail. While their tails are the same length, the small-footed myotis' tail extends 2–3mm after the connecting membrane ( Uropatagia) which makes it appear longer. The dental formula for ''M. californicus'' is Behavior Activity During the day, the California myotis will roost in the bark of dead trees, particularly ponderosa pines, r ...

Nest Box
A nest is a structure built for certain animals to hold eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be composed of organic material such as twigs, grass, and leaves, or may be a simple depression in the ground, or a hole in a rock, tree, or building. Human-made materials, such as string, plastic, cloth, or paper, may also be used. Nests can be found in all types of habitat. Nest building is driven by a biological urge known as the nesting instinct in birds and mammals. Generally each species has a distinctive style of nest. Nest complexity is roughly correlated with the level of parental care by adults. Nest building is considered a key adaptive advantage among birds, and they exhibit the most variation in their nests ranging from simple holes in the ground to elaborate communal nests hosting hundreds of individuals. Nests of prairie dogs and several social insec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
