Eastern Small-footed Myotis, Myotis leibii

The eastern small-footed myotis (Myotis leibii), also known as the eastern small-footed bat, is a vesper bat that can be found in North America. Its range includes Quebec and Ontario in Canada and eastern areas of the United States including Georgia and Oklahoma. It roosts in a number of areas, but in mountains regions, it can be found at altitudes between 787 and 3,690 feet. Roosts include mines and caves during the winter, and rock bluffs, turnpike tunnels, and buildings in the summer.

The eastern small-footed myotis can reach an average body length of up to 3.7 inches, with a wingspan between 8.3 and 9.8 inches. Its soft fur is typically tannish yellow or brownish gold in color with a grey underbelly and a white face, wings, and ears. It can be distinguished from other small bats by its black facemask and by its tiny feet.

Although there is not much information on the eastern small-footed bat’s reproductive habits, it is known that its breeding season occurs in the fall season and that pregnancy is delayed until spring. This is a common occurrence among bat species. Pups are born during late May to July. The oldest of this species was recorded at twelve years of age. The eastern small-footed myotis appears on the IUCN Red List with a conservation status of “Least Concern.”
