This video shows an emergence of lesser horseshoe bats from the roof space of a building near BSG Ecology’s Monmouth office. It was taken during a training evening led by Principal Ecologist Matt Hobbs on Monday 22nd July 2013.
The roost supports at least 350 adult lesser horseshoe bats, and forms one of four component sites that have been notified as the Wye Valley Lesser Horseshoe Bats SSSI.
The echolocation calls of passing bats were detected using a batbox duet and can be heard as a periodic high pitched warble on the accompanying audio.
