Reflections on nature in a garden in France

Is it worth it?

We have always believed that we share the house and garden with the animals that frequent it ( see the old 2017 post “We give nature a home..”. In fact, they share their garden with us rather than the other way around.

A Barbastelle bat had been visiting us since 2016 (see “Return to the garden in March”) and recently we have noticed what we think is a common Pipistrelle bat behind the shutters and sometimes in our garden parasol. I did not think that roosting behind shutters in wet weather was an ideal site for the bats.

In the winter of 2019, Kourosh built and installed a bat box. We looked through the internet to get the best advice we could find on sizes and places and height to mount the box. You can see that the box has been placed on a sheltered spot. The problem is that access is difficult and so we were never sure if it was being used.

Last week Kourosh decided to get out his long ladder and have a look. The tell tale droppings on the ledge underneath the box was enough to reassure us that the box was being used.

After the installation of the first bat house, we realised that it would be difficult to monitor and also I had my doubts about the suggestion of such a high position for a bat box. After all, the bats had chosen the downstairs shutter and quite a narrow installation. Kourosh listened to my concerns and built me a MarkII bat house with the same interior width as the space behind the shutter.

The problem is that underneath the bat box MarkII it is difficult to see any droppings because of the flowers.

Once again Kourosh came to my rescue because there is no way you can see inside a long bat box. He had purchased a Potensic endoscope some years ago before even he had a smart phone. Now he was able to join it to his mobile phone and guess what!

The lower bat box had an occupant which you can see on this short (6 sec.) video.

I think it is a common Pipistrelle (Pipistrellus pipistrellus). The best way to identify bats from a photograph is to look at their ears. Like many identifications from photographs, it is not exact and if anyone is more knowledgeable about bats I would love to hear from them. I believe that a more exact identification can be made using equipment that can detect their echolocation cries which are specific to the species of bat and these detectors are used by people who study bats.

Here, in the Charente Maritime, the fields for monoculture of vines, maize, sunflower and oilseed rape are increasing in size as hedges are cut to join up the fields and woodland is removed to create more arable land. This means less habitat for the bats and of course the flying insects that they consume. In addition, modern farm buildings offer less places for the bats to roost.

We were very happy with our discoveries and sat down to enjoy a morning coffee.

We needed to use the parasol because of the sun but when we opened it we found it was already in use.

I’ve turned this image to give you a less upside down image of the bat. Needless to stay, we had to get our sun hats to enjoy our coffee outside! Luckily, the bat does not always take up residence in the parasol.
