The Wagner whiskered bat ( Pteronotus personatus ) is a bat species from the chin-leaf bat family (Mormoopidae), which is native to Central and South America.
description
Pteronotus personatus is a small bat with a head-trunk length of 65 mm and a forearm length of 43.2 mm. The fur is usually reddish to black-brown. The ears are pointed and pointed forward. The lower lip is noticeable and has papillae. The nose is enclosed in folds of the upper lip. The wings are attached to the side of the animal's body and end at the ankles. The tail membrane is large and hairless with a long, thin calcar .
The Wagner mustache bat looks very similar to P. parnellii , but is much smaller. In contrast to P. davyi , the wings are not connected above the back. The labionasal plate is simply shaped and has no outgrowths as in P. macleayii and P. quadridens .
Way of life
Pteronotus personatus , like most bats, is nocturnal and feeds on insects that are caught in flight. The flight speed can reach up to 20 km / h.
The complex echolocation calls consist of a series of constant-frequency tones, followed by a frequency-modulated middle section and a short, constant-frequency end. The calls move between 36 and 85 kHz and are therefore not audible to the human ear.
During the day, the animals can be found in colonies of up to 15,000 individuals in warm, moist caves and mines. The species often shares such places with its sister species P. davyi and P. parnellii , but also with Mormoops megalophylla , the common vampire ( Desmodus rotundus ), Leptonycteris curasoae and Natalus stramineus .
The females are seasonally momoestrous and give birth to a single young each in June or July. The birth falls at the beginning of the rainy season, during which the insect density increases and the mother is thus supplied with enough food to be able to produce sufficient milk for the young animal.
distribution and habitat
The Wagner mustache bat occurs from Mexico to Brazil and Bolivia . The species is classified as harmless by the IUCN .
