The cinnamon brown mouse- eared mouse ( Myotis fortidens ) is a bat in the smooth-nosed family that is found in Central America.
features
The species is a small member of the genus with a head body length of 47 to 63 mm, a tail length of 30 to 43 mm and a weight of 5 to 8 g. It has 35 to 40 mm long forearms, 7 to 10 mm long hind feet and 13 to 15 mm long ears. The slightly woolly fur on the top is made up of hairs 5 to 7 mm long. It is colored from cinnamon brown to orange-yellow. On the underside, the hair near the root is black and then white, resulting in a cream-colored fur. The cinnamon-brown mouse-ear has black flight membranes and a thin hairline on the edges of the tail flight membrane. In the upper jaw there is only a small premolar in front of the normal-sized “third” premolar , which distinguishes the species from other mouse ears. In addition, other yellowish generic members in America are restricted to mountains.
Distribution and way of life
The distribution area extends from western Mexico along the Gulf of California to Guatemala . The cinnamon mouse-eared mouse can be found in the lowlands in dry forests or in partially deciduous forests and visits adjacent areas.
The species uses various resting places such as caves, tunnels, thatched roofs or other structures as well as tree hollows, rolled up leaves (e.g. from heliconias ) or hollowed stems of thistles . Often a few specimens share a hiding place, keeping a little distance from each other. The animals usually fly slowly and unsteadily at a height of 2 to 4 meters. Although there is no study of the prey of the cinnamon mouse-eared mouse, it is believed that the diet consists of insects. According to isolated observations, the offspring are born in May.
status
There are no threats to the population. The IUCN lists the species as not endangered (least concern) .
