These videos show some recent bat emergences on surveyed properties. Homeowners often have no idea that they have bats roosting in their properties. The first video shows a few of the 40 bats that emerged from beneath hanging tiles just outside their bedroom window. They hadn’t heard or seen them before. This emphasises the need to carry out dusk emergence surveys and bat surveys in general. If we hadn’t a maternity colony could have been disturbed or worse.
