The Handley long-nosed bat ( Anoura cultrata , Syn . : Anoura brevirostrum , Anoura werckleae ) is a species of bat from the leaf-nosed family (Phyllostomidae), which is native to South America.
description
The Handley long-nosed bat weighs on average 17.1 g, with males being slightly larger than females. The muzzle and tongue are long, the ears small and round. The fur color is variable, from dark brown to reddish brown to light brown, whereby the peritoneum is paler than the fur on the back. The forearm and tail membrane are hairy. The flight membrane appears black to brown-black, while the ears are gray to gray-black.
Anoura cultrata differs from Anoura caudifer and Anoura geoffroyi in features of the teeth, including the enlarged upper incisors.
Way of life
The Handley long-nosed bat uses caves and buildings as a roost during the day, where this species is often found together with Anoura geoffroyi , Anoura caudifer , Carollia perspicillata and Pteronotus parnellii , as well as regionally with fat swallows . The species is mainly found in mountain rainforests .
Anoura caudifer feeds on nectar, pollen and insects, although the respective proportion of the diet is unclear. Since nectar is part of the diet, Anoura caudifer is an important pollinator of various flowering plants.
Little is known about the reproduction of the Handley long-nosed bat. A pregnant female was caught in Costa Rica in August. Suckling females were found in Colombia in July and in Peru in August. The females usually give birth to a single young animal; Twin births are rare. Newborns weigh between 3 and 3.7 grams.
distribution and habitat
The distribution of the Handley long-nosed bat ranges from Costa Rica to Bolivia . The IUCN classifies their population as potentially endangered. The main threat comes from habitat destruction, which is why populations are declining.
