Mexican Free-tailed Bat
The Mexican free-tailed bat or Brazilian free-tailed bat (''Tadarida brasiliensis'') is a medium-sized bat native to the Americas, so named because its tail can be almost half its total length and is not attached to its uropatagium. It has been claimed to have the fastest horizontal speed of any animal, reaching top ground speeds over . It also flies the highest among bats, at altitudes around . It is regarded as one of the most abundant mammals in North America. Its proclivity towards roosting in huge numbers at relatively few locations makes it vulnerable to habitat destruction in spite of its abundance. For instance, up to 1.5 million bats reside under just one bridge in Austin. The Texas Legislature designated the Mexican free-tailed bat the state mammal (flying) in 1995. The bat is considered a species of special concern in California as a result of declining populations. Taxonomy The Mexican free-tailed bat was described as a new species in 1824 by French zoologist Isi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Red Bat
The western red bat or desert red bat (''Lasiurus frantzii'') is a species of microbat in the family Vespertilionidae. It is found in western North America and Central America. Taxonomy Previously, it was believed to be a subspecies of the southern red bat (''Lasiurus blossevillii''), and was called ''Lasiurus blossevillii teliotis'' (abbreviated ''L. b. teliotis''). The western red bat is also very similar to the eastern red bat and is distinguished from each other by minor differences, such as the lack of white-tipped hair in the dorsal pelage in the western red bat and the presence of sparse fur in the lower third of their tail. Their habitats are separated by the Rocky Mountains and may overlap. Distribution and habitat The western red bat is found across western North America, ranging from southern Canada, through the western United States, down to Central America. The species has been recorded in Belize, Canada, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver-haired Bat
The silver-haired bat (''Lasionycteris noctivagans'') is a solitary migratory species of vesper bat in the family Vespertilionidae and the only member of the genus ''Lasionycteris''.

Description This medium-sized bat is predominantly black (including the wings, ears, interfemoral membrane, and fur) with white-tipped hairs. The basal upper half of its tail membrane is densely furred. This gives the bat a frosted appearance and its common name's sake. This species has a flattened skull with a broad rostrum. This species weighs around 8–12 g, has a total length of ~100 mm, a tail length of 40 mm, and a forearm length of 37–44 mm.

Spotted Bat
The spotted bat (''Euderma maculatum'') is a species of vesper bat and the only species of the genus ''Euderma''. Description The spotted bat was first described by zoologist Joel Asaph Allen from the American Museum of Natural History in 1891. It can reach a length of 12 cm and a wingspan of 35 cm. The weight is about 15 g. It has three distinctive white spots on its black back. With ears that can grow up to 4 cm, it is said to have the largest ears of any bat species in North America.

Big Brown Bat
The big brown bat (''Eptesicus fuscus'') is a species of vesper bat distributed widely throughout North America, the Caribbean, and the northern portion of South America. It was first described as a species in 1796. Compared to other microbats, the big brown bat is relatively large, weighing and possessing a wingspan of . Big brown bats are insectivorous, consuming a diverse array of insects, particularly night-flying insects, but especially beetles. Some of the beetles it consumes are serious agricultural pests, including cucumber beetles. They are nocturnal, foraging for prey at night and roosting in sheltered areas during the day such as caves, tunnels, tree cavities, and human structures. Their breeding season is in the fall, shortly before their annual hibernation. After hibernation ends in the spring, females form maternity colonies for giving birth to young. Oftentimes only one offspring is produced per litter, though twins are common in the Eastern US. Lifespans o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
