Now we just need to perfect that ridiculous Christian Bale Batman voice.
If you're anything like us, you spend most of your free time pretending to be The Caped Crusader, so today's news of an app that can help record the presence of the winged creatures of the night is a timely boost for the weekend's festivities.
With the aid of an ultrasonic microphone the iBats application for Android and iPhone can capture the inaudible-to-the-human ear calls of 900 different species of bat around the world.
The app is designed for the purposes of the 700-strong volunteer bat-spotting members of the iBats website. Once you've made your recording the app will upload it to the website where specialised software will identify the species.
iBats project manager Kate Jones says: "Bats are like a heart monitor for wildlife.
"Their presence can tell us a lot about the health of the environment because they have an important role in terms of eating insects and acting as pollinators for many different plant species."
"We hope the iBats app will encourage more people to monitor their local bats and make a contribution to the global conservation of wildlife."
The free app is available to download from the App Store and Android Market now.
