The fringed bat ( Myotis nattereri ) belongs to the subordination of the bats (Microchiroptera) and is assigned to the smooth-nosed family (Vespertilionidae). The scientific species name honors the Austrian zoologist Johann Natterer (1787–1843).
features
The name of this species goes back to firm, fringed hairs on the tail skin. It has a brownish-gray dorsal fur coloration. Their fur is long-haired and loose. In contrast, their undercoat is light gray to white.
It is 40 to 50 millimeters long from torso to head, has a wingspan of 245 to 280 millimeters and weighs 5 to 10 grams.
The ears of the fringed bat are relatively small. These usually do not reach 20 millimeters. As with other species from the genus of the mouse ears ( Myotis ), the ears are longer than wide, membranous and thin and with an elongated ear cover - tragus .
nutrition
It feeds on small insects such as flies , mosquitoes and moths, but also caterpillars and spiders are among its prey animals. The forest is one of their hunting grounds , above all layers of forest near the ground.
Resting places
In summer she looks for quarters in holes or hollows in facades. However, it usually does not stay there for long, because it usually changes its location every 1 to 4 days. As winter quarters, she prefers underground cavities such as the Segeberger Kalkberg Cave , bunkers or old cellar vaults. However, fringed bats are also regularly observed with frostbite on the tips of their ears. It is therefore quite possible that some of the fringed bats overwinter in above-ground locations that are not frost-proof, such as in tree hollows.
threat
The fringed bat is under nature protection . One of the main problems for the native bats is the lack of suitable day and winter sleeping quarters as well as roosts for nurseries in which the young are born and are cared for by the mother until they are independent. Due to extensive facade renovations, the number of roosts for the fringed bat has rapidly decreased.
