Description

The elegant myotis is a small bat, with a body weight of about 4 g. Its fur is brown on the dorsal side while the ventral side is lighter and golden. Its ears are pale brown, and its flight membranes are slightly darker than its fur. The ears feature a slender and deeply notched tragus. The following body measurements are in millimeters (mm). Total body length: 76.0, length of tail: 35.0, length of hind foot: 7.0, length of ear: 12.0, tragus: 6, forearm: 34.2, and, the greatest length of skull: 13. [2] [3]

When compared to the California Myotis (M. californicus) and the Western small-footed bat (M. ciliolabrum), M. elegans has a shorter tail, a more pronounced golden color on its underparts, a deeper notch in their tragus, and a shorter skull. It is further differentiated from M. ciliolabrum by its paler ears, lips, and flight membranes, shorter ears, and a more slender tragus.

Like most vesper bats, M. elegans produces short duration frequency modulated (FM) echolocation calls above 50 kHz in frequency. [4]

Biology and behavior

Little is known about the life history and behavior of the elegant bat. They are known to inhabit dry deciduous forests in El Salvador. [3]

Based on fecal analysis, M. elegans is known to prey on insects of the Lepidoptera, Coleoptera and Diptera orders. [5] [6] Due to low sample size in existing studies, it is likely not a complete list of prey items for this species.

The spectral bat, also called the great false vampire bat, great spectral bat, American false vampire bat or Linnaeus's false vampire bat, is a large, carnivorous leaf-nosed bat found in Mexico, Central America, and South America. It is the only member of the genus Vampyrum; its closest living relative is the big-eared woolly bat. It is the largest bat species in the New World, as well as the largest carnivorous bat: its wingspan is 0.7–1.0 m (2.3–3.3 ft). It has a robust skull and teeth, with which it delivers a powerful bite to kill its prey. Birds are frequent prey items, though it may also consume rodents, insects, and other bats.

The little big-eared bat is a bat species in the order Chiroptera and family Phyllostomidae. It is from South and Central America particularly Colombia, Venezuela, Guyana, French Guiana, Brazil, Peru, Ecuador, Bolivia, Argentina, Paraguay, Suriname and Trinidad. Though its exact population is unknown, it is considered widespread and occurs in protected areas, although deforestation may be a minor threat, it is classified as Least Concern. It is found in multistratal evergreen forests and dry thorn forests and forages near streams and is found hollow trees, logs, caverns, or houses with groups up to twelve. The head and body length measures at 44 millimetres (1.7 in) for males and 45 millimetres (1.8 in) for females. Males usually weigh about 5 grams (0.18 oz) while females weigh 5.7 grams (0.20 oz).

<span class="mw-page-title-main">Eastern small-footed myotis</span> Species of bat

The 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.
