PICTURE SHOWS: Bat Conservation International and collaborators capture the first-ever recording of Hill???s horseshoe bat A 'comical-looking' critically endangered bat not seen in 40 years and feared extinct has been found in Rwanda. Two Hill's horseshoe bats (Rhinolophus hilli), which haven't been seen since 1981, were found by scientists in the forest at the Nyungwe National Park, in Nyungwe. Hill's horseshoe bat has 'exaggerated' and 'comical' facial features, including a huge pair of ears and a horseshoe-shaped nose covered with loose flaps of skin. The mysterious species, which is endemic to Rwanda, is thought to roost in caves or old mining tunnels in tropical forests. It's listed as 'critically endangered' by the IUCN's red list, and had been considered a 'lost species' prior to its 'incredible' rediscovery. ??sGoing into this project we feared the species may have already gone extinct. Rediscovering Hill???s horseshoe bat was incredible ??" it???s astonishing to think that we???re the first people to see this bat in so long???, said Dr. Jon Flanders, BCI???s Director of Endangered Species Interventions. ??sNow our real work begins to figure out how to protect this species long into the future.??? The rediscovery marked the culmination of survey efforts that started in 2013, as the team???s dedication paid off during a ten-day and night expedition to Nyungwe National Park in January 2019. Dr. Winifred Frick, BCI???s Chief Scientist, recalled, ??sWe knew immediately that the bat we had captured was unusual and remarkable. The facial features were exaggerated to the point of comical. Horseshoe bats are easily distinguishable from other bats by characteristic horseshoe shape and specialized skin flaps on their noses???. Careful measurements of the bat before they released it back into the wild were an early tip-off that this could be the lost species they came to find. Dr. Flanders then travelled to visit museum archives in Europe to compare the only known specimens to verify that what they had captured in the African forest was, in fact, the first evidence in 40 years that Hill???s horseshoe bat still exists. Catching this elusive species also allowed the team to collect additional information to ensure it is easier to find in the future ??"including recording the first-ever echolocation calls that Hill???s horseshoe bat emits as it hunts for insects. ??sKnowing the echolocation calls for this species is a game-changer," said Dr. Paul Webala, Senior Lecturer at Maasai Mara University, and one of the team???s lead scientists. Since catching the pair of Hill???s horseshoe bats, the Nyungwe Park Rangers have been setting out detectors that ???eavesdrop??? on the bats during their nightly flights through the forest. The rangers conducted audio surveys with Wildlife Acoustics bat detectors in 23 locations over nine months resulting in recording a quarter-million sound files. Analysis of the sound files revealed Hill???s horseshoe bats were heard at eight locations, all within a small area. ??sAll the work so far confirms that this is a very rare species with a very small core range. We look forward to collaborating with the Rwanda Development Board and Nyungwe Management Company to strengthen the existing conservation efforts to ensure it stays protected,??? said Dr. Frick. Careful planning and strong partnership support between all the agencies, organizations and experts involved in this initiative were key to its success, according to Dr. Olivier Nsengimana, founder and executive director of the Rwanda Wildlife Conservation Association.
