Distribution area of the Ridley round-leaf nose

The Ridley round-nosed nose ( Hipposideros ridleyi ) is a bat in the round-nosed nose family that is found in Southeast Asia . It is named after the British botanist Henry Nicholas Ridley .

features

The species reaches a head body length of about 49 mm, a forearm length of 47 to 51 mm, a wingspan of about 100 mm and a weight of 7 to 12 g. The 25 to 29 mm long tail is almost completely embedded in the tail membrane. The 25 to 30 mm long ears are noticeably large in relation to the body. Furthermore, the Ridley round-blade nose has a large nose blade that covers almost the entire muzzle. The coat is made up of hairs that are uniformly brown over their entire length.

Distribution and way of life

Three populations are known for the Ridley round-leaf nose, which live in the south of the Malay Peninsula and in the north-west and north of Borneo . The animals can be found in the lowlands and in the hill country up to 500 meters in height. They occur in pristine forests and in forests with wing fruit plants .

Dormant specimens were found in tree hollows in fallen trees or rarely in passages. Occasionally up to 15 individuals use the same hiding place. Like other family members, the Ridley round-leaf nose hunts with the help of echolocation , whereby the sounds have a frequency of 65 to 67 kHz. Females with active teats ( lactation ) were registered in April and May.

status

Deforestation, fires and other landscape changes have a negative impact on the bat. The IUCN assumes that the population will decrease by 30 percent over the course of 10 years (from 2008). The species could be registered in different protected areas. It is considered endangered (vulnerable) .
