An ecologist's handheld detector picks up a rarely recorded bat 650 km from its last known spot
Australian Wildlife Conservancy said that ecologist Oli Aylen, nicknamed the Batman by colleagues, recorded the call of an Arnhem Sheath-tailed Bat at Pungalina-Seven Emu Wildlife Sanctuary, on Yanyuwa and Waanyi-Garawa Country in the Northern Territory. He was setting up mist nets around mangroves and happened to have his handheld bat detector running. The species, first described in 1979, has very few confirmed recordings; its previous easternmost detection was near Jabiru, about 650 km away. Aylen noticed the unusually short call, and Damian Milne, a bat specialist with the Northern Territory government, confirmed it. The conservancy says the bat will now be a priority in its surveys, with the hope of finding where it roosts.
Knowing a shy animal lives further than anyone thought is the first step to looking after the places it needs.
This is one acoustic recording, not a captured or photographed bat, and nobody yet knows how many live there or whether the species is threatened. Some coverage converted the distance to about 400 miles.
