Myotis keenii (Merriam, 1895) | |
Keen's myotis (Myotis keenii) is a species of vesper bat. It is found in British Columbia in Canada and in Washington and Alaska in the United States. [1] 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. [2] Classification for Keen's myotis formerly included the northern long-eared myotis (Myotis septentrionalis), resulting in older studies confusing the species for one another. [3]
Measurements: Forearm 1.4-1.6 in., WT 0.25–0.33 oz (7.1–9.4 g). Average body length 8–9 cm, tail length 4–5 cm. [4] In appearance, Keen's myotis is very similar to other long-eared bats of the same range, with characteristic dark brown patches on the shoulders. [5]
Keen's myotis prefers coastal habitats, but is often found in urban areas as well. It frequently roosts in trees and rock crevices. [6] It is nocturnal and insectivorous. [5] Keen's myotis probably exhibits the same breeding habits of other temperate vespertilionids, but there is little data available. [7]
In the wild, Keen's myotis is recorded living upwards of 12 years, [8] while in captivity, it is reported living 19 years. [7]

The flat-headed myotis is a species of vesper bat. It is endemic to Mexico where it is found in certain montane forests in the Sierra Madre Oriental in the northeast of the country. Once thought to be extinct, this bat was rediscovered in 2004 by Joaquín Arroyo-Cabrales and colleagues. The species is now classified as endangered by the IUCN.

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.
Vampyriscus nymphaeus is a species of bat in the family Phyllostomidae, the leaf-nosed bats. It is known commonly as the striped yellow-eared bat. It is native to Colombia, Costa Rica, Ecuador, Nicaragua, Panama, and Honduras.
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.
The dark-nosed small-footed myotis is a species of mouse-eared bat in the family Vespertilionidae, described in 1890, and indigenous to Canada, Mexico, and the United States. While the International Union for Conservation of Nature suggests that M. melanorhinus is uncommon, the species nonetheless enjoys an extensive habitat, at least encompassing British Columbia, central Mexico, and Oklahoma.
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.
