The Lesser of Two Noctules

Everyone’s a sucker for a noctule. Big, brassy, sassy bats with an attitude. They’re about half a guinea pig in size (or, say, two large Syrian hamsters – ok bear with me, I’m trying here…) they are one of our larges UK Bats. I’ll admit that there’s something rather special about noctules – such a substantial bat is a novelty when the largest bat we see frequently in bat boxes is a Brown Long Eared bat and more often than not, our tiny Pipistrelles. However, size isn’t everything. There is something incredibly fascinating about Leisler’s Bats (aka Lesser Noctules). A calmer, generally more diminutive version of their larger namesake, there is something very inquisitive about their expression that I’m just in love with. (I blogged about the differences between the species a few months ago) I also hinted at surveys to come, so here we are – the beginning of a new bat box scheme aimed at recording Leisler’s bats at an almost entirely un-surveyed woodland.

I rallied the BrumBats on Saturday to put up 25 bat boxes of different designs, many of which were rescued and repaired from other sites where they had been subject to vandalism. Six of the boxes were generously donated by local resident and wildlife enthusiast Sammy Benbow who came along to help us put them up. (Sammy is now one of the list of people that I’ve known on the internet for ages and have now actually met in real life! I love it when that happens!)

It is also going to give us an indication of whether bats simply take a long time to colonise boxes, or if it is because they are new boxes, as we’ve in several places hung them up in pairs: one old/refurbished box that has been outdoors for years & one brand new box. If the bats simply prefer the ‘new house smell’ to have dissipated before they move in, then they’re likely to go for the older boxes first. If they don’t much care either way, then we can expect them to go for both ages of box equally. (Of course, there is not enough of a sample size to reach any kind of quantifiable conclusion, but it is just a matter of curiosity on my part.)

So I’d like to say a huge thanks to Sammy, Jenny, Katie, David, Chris, Mike and Scott for helping on the day, braving the heights, the cold, the mud, the damp and the manual labour, all for the love of bats…
