The tailed long-nosed bat ( Anoura caudifer ) is a species of bat from the leaf-nosed family (Phyllostomidae), which is native to South America.
description
The tailed long-nosed bat is a relatively small species of bat with a total length of 47 to 70 mm. The muzzle and tongue are long, the ears small and round. The fur is dense, silky and mostly dark brown. The tail is short and embedded in the tail membrane. The species differs from Anoura cadenai and the wide-toothed long-nosed bat ( Anoura latidens ) by the presence of the tiny tail. In contrast to Geoffroy's Tailless Bat ( Anoura geoffroyi ), it has a fully developed calcar .
Way of life
Colonies of the long-nosed bat usually consist of 5–15 individuals, but can reach a size of up to 100 animals. During the day, tree hollows, tunnels and caves are used as sleeping places. This species is often found in caves together with Anoura geoffroyi , Anoura cultrata , Carollia perspicillata and Pteronotus parnellii .
The tailed long-nosed bat feeds mainly on nectar from various plants, including various neotropical legumes , passion flowers and marcgravia , with smaller flowers likely being preferred. This makes them an important pollinator for these plants. In order to meet the energy requirements, Anoura caudifer has to visit around 800 flowers over 4 hours. She covers a distance of around 50 km every night.
Little is known about the reproduction of the long-nosed bat, and the timing seems to vary locally.
distribution and habitat
The distribution of the tailed long-nosed bat ranges from Colombia to Argentina , leaving out the Amazon basin of Brazil . Their population is classified by the IUCN as stable and non-threatened thanks to their widespread distribution and likely large populations. However, like most Neotropical bats, this species is also affected by habitat destruction.
