The spotted bat (Euderma maculatum) is a species of vesper bat and the only species of the genus Euderma.
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. [2] The spotted bat's mating season is in autumn and the females produce their offspring (usually one juvenile) in June or July. Its main diet is grasshoppers and moths.
The spotted bat is a largely Western North American species, typically found west of the Rocky Mountains, from southern British Columbia to the U.S.-Mexico Border of Arizona and California—although sightings have occurred as far away as southwestern Montana, near Bozeman, and as far south as Pachuca (Hidalgo), México. [3] The species' favored habitat varies, from undisturbed cliffside roosts along the Grand Canyon, in Arizona, to open and dense deciduous and coniferous forests as far north as southern British Columbia. Additionally, the species may be found in hay fields, deserts, marshes, riparian zones, or chaparral habitats.
Some of the most northerly sightings of the spotted bat have taken place in Canada, near Cache Creek and Vancouver, British Columbia; however, it is primarily known from the states of California, Arizona and Nevada, as well as parts of western Colorado, Idaho, Oregon, New Mexico, Utah and Washington. [3]
Use of pesticides such as DDT and other insecticides in the 1960s led to a severe decline in the spotted bat population, but current observations had shown that it is more common than formerly believed. Abundance, population trend, and threats are widely unknown.
The spotted towhee is a large New World sparrow. The taxonomy of the towhees has been debated in recent decades, and until 1995 this bird and the eastern towhee were considered a single species, the rufous-sided towhee. Another outdated name for the spotted towhee is the Oregon towhee. The call may be harsher and more varied than for the eastern towhee.
The spotted owl is a species of true owl. It is a resident species of old-growth forests in western North America, where it nests in tree hollows, old bird of prey nests, or rock crevices. Nests can be between 12 and 60 metres high and usually contain two eggs. It is a nocturnal owl which feeds on small mammals and birds. Three subspecies are recognized, ranging in distribution from British Columbia to Mexico. The spotted owl is under pressure from habitat destruction throughout its range, and is currently classified as a near-threatened species.
The Mexican free-tailed bat or Brazilian free-tailed bat 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 99 mph (160 km/h). It also flies the highest among bats, at altitudes around 3,300 m (10,800 ft).
The hog-nosed skunks belong to the genus Conepatus and are members of the family Mephitidae (skunks). They are native to the Americas. They have white backs and tails and black underparts.
The 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.
The western spotted skunk is a spotted skunk of western North America.
The fauna of the United States of America is all the animals living in the Continental United States and its surrounding seas and islands, the Hawaiian Archipelago, Alaska in the Arctic, and several island-territories in the Pacific and in the Caribbean. The U.S. has many endemic species found nowhere else on Earth. With most of the North American continent, the U.S. lies in the Nearctic, Neotropic, and Oceanic faunistic realms, and shares a great deal of its flora and fauna with the rest of the American supercontinent.
The western mastiff bat, also known as the western bonneted bat, the greater mastiff bat, or the greater bonneted bat, is a member of the free-tailed bat family, Molossidae. It is found in the Western United States, Mexico and South America. This species is the largest bat native to North America, and some of its distinguishing characteristics are its large ears, wings, and forearms. The subspecies Eumops perotis californicus is a species of concern as identified by the U.S. Fish and Wildlife Service. The range of this subspecies is principally southwest desert regions of the United States, along the border with Mexico; however, the range extends as far north on the Pacific coast as Alameda County, California.
The western yellow bat is a species of vesper bat found in Mexico and the southwestern United States. This species roosts in trees such as Populus fremontii, Platanus wrightii, and Quercus arizonica. If available, the western yellow bat will use the dead fronds that encircle palm trees as a roosting site.
The southwestern myotis is a species of vesper bat. It is found in Guatemala, Mexico, and the United States.
The western small-footed bat, also known as the western small-footed myotis, is a species of vesper bat native to North America.
The fringed myotis is a species of vesper bat that is found in British Columbia, Mexico, and the western United States.
The Yuma myotis is a species of vesper bat native to western North America.
The greater long-nosed bat or Mexican long-nosed bat is a species of bat in the family Phyllostomidae. It is found in Mexico and the United States. It chiefly consumes pollen and nectar, particularly from agave plants and cacti. Its habitat includes desert scrub and open woodlands, however, it is threatened by habitat loss.
The pocketed free-tailed bat is a species of bat in the family Molossidae found in Mexico and in Arizona, California, New Mexico, and Texas in the United States. They resemble the Brazilian free-tailed bat but differ morphologically. They are recognized as "least concern" by the IUCN and as "apparently secure" by Natureserve.
The 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.
There are eighteen indigenous species of bats in Canada, which are found in many parts of the country. They are insectivores, and are prey to falcons, hawks, owls, snakes, cats, and raccoons.
Plecotini is a tribe of bats in the family Vespertilionidae. It contains several genera found throughout the Northern Hemisphere, in Eurasia, North Africa, and North America. Several genera in this tribe are known as big-eared bats or long-eared bats. It also contains the spotted bat and barbastelles.
