It's not glamorous, I don't even get to be outside in the sunshine, but its got to be done; trawling through 12 nights of bat detector data from a site we've been working on in Herefordshire.
One of the types of survey we do involves placing remote ultrasonic recording devices on sites. These record the echolocation of bats as they pass by. We use the recordings to identify what species are present and the level of activity over several nights (or months in some cases).
Amongst the usual pipistrelles and myotis species I had a run of Barbastelle and greater horseshoe - if you don't know what they are, I'd compare it to finding a Ferrari and a Lamborghini in a barn full of rusty ford fiestas!

We don't get these species up here in Yorkshire, so it's a proper treat for a northern bat worker even if I did have to spend all afternoon staring at a computer to get to them.
