To ascertain the ecology of M. mystacinus at its geographic range extreme, the roosting behaviour, home range and habitat use of females in a maternity roost in Ireland was investigated by radio-tracking. Whiskered bats often appear in pairs, but not large groups like the Pips. On a bat detector, the calls sound like a series of clicks, but are quiet and can be difficult to detect. (1999) into the foraging behaviour of Leisler's bats in Ireland found that their foraging behaviour varied with reproductive stage. Ireland is positioned at the most western extreme of this species’ range. People’s Trust for Endangered Species was set up in 1977 to save our wildlife. Back to top. Brandt’s bat is more often in woodland than the whiskered bat. Nowadays 23 species are critically endangered due to habitat loss or conflict with people. With extremely elongated fingers and a wing membrane stretched between, the bat’s wing anatomically resembles the human hand. The recording was made along the Noke Common Road on the eastern edge of the Forest close to the lay-by between the Noke and Hillis Gates. You can see the ground reflection too. Bats are one of the most important groups of mammals in terms of ecosystem function. The whiskered bat (Myotis mystacinus) and related species, are small European bats with long fur.Although uncommon, M. mystacinus is often found around human habitation and around water; it is similar to Brandt's bat Myotis brandtii, from which it was distinguished as a separate species only in 1970.
