Buying an old property often means you get rather more than you bargained for… and I don’t just mean dry rot, woodworm and a leaky roof – I mean resident wildlife!
I hadn’t been living at Victoria Farm long when a chap knocked on the front door and politely told me I had bats! A bat enthusiast who lived in the village, he had seen bats going in and out of an attic in one the old farm buildings we have here.
So, he came along one evening with his bat detector/counter, sat in the dusk watching a hole up in the gable end of the building and then, having checked up in the attic, told us we were the proud ‘owners’ of a lesser horseshoe bat nursery roost! I know, not the sort of thing you get told every day, but there you are, that’s rural living!
The bat gets its name from its horseshoe-shaped nose. It is one of the world’s smallest bats, weighing only about 8 grams, with a wingspan up to 25 cm and a body length of about 4cm – so less than 2 inches – really tiny!
Bats are protected and cannot be disturbed. Luckily for us, the attic has always been unused and their roost is no inconvenience at all. We respect their space, keep the access free of vegetation, and they get on and do what mummy bats do.
Contrary to what you might think, they don’t make a lot of mess. As they eat only insects their droppings are fine and powdery – we call it ‘bat dust’.
Over the 27-odd years I’ve lived here now, the colony has grown and, at the last count, had around 140 little bats in it. If we sit outside on a warm summer’s evening, you can see them flitting about and flying off down the valley but, other than that, we are not aware of them.
The colony is made up of breeding mothers and their young. Females give birth to one pup weighing less than 2 grams at birth. The bats are only with us for three months each year – June, July and August – so I expect any day now, they will start arriving, finding their place in the roof and settling down to give birth and rear their young. The mothers, and their daughters, will then return to the roost next year and so the cycle continues…
Sadly, lesser horseshoe bats are in decline due things such as the disturbance of roosts, changes in agricultural practices and the loss of suitable foraging habitats. Well, be assured – no-one is going to disturb our bats – long may they thrive!
