Wild Animals/Bats


Yesterday morning we woke to find a bat roosting on our brickwork , it was there all day and we naturally thought it would leave at dusk , but to our surprise today it is still in the same position . Last night it was quite wet weather but could you let me know if this normal ,I have purchased a bat box to try to keep them safe my thanks

Dear Ken

Thank you for your question and for buying a bat box. I also wish to thank the authors of the websites I used.

Bats avoid flying if the energy taken to find food is more than the energy obtained from the food. This is also the case with many other mammals. https://canalrivertrust.org.uk/news-and-views/features/how-to-spot-bats says that bats donít like hunting insects in wet weather as the moisture in the air confuses their echolocation system. http://www.eastdorsetbatrehab.btck.co.uk/Bat%20facts says if there are consistent wet nights, bats can become emaciated due to the lack of flying insects. http://rsbl.royalsocietypublishing.org/content/early/2011/04/29/rsbl.2011.0313 goes into more details about the problems facing bats during wet nights.

If there are several wet nights, please contact the Bat Conservation Trust helpline on 0845 1300 228 or locally us on 07746 743221, as the bat may need help.

http://lrbatgroup.btck.co.uk/ gives details about the Leicestershire & Rutland Bat Group. Hopefully you can join the group.

All the best

I can answer questions about wild mammals and other animals, as well as extinct animals and zoos. I am not an expert about every animal species. I can look up information from books and the internet, but can't verify if all the information is true. Please don't ask questions about: 1. Pets. I am not a vet. Please contact a vet if your pet is ill. You may need to spend some money if you want your pet to live. Don't get a pet if you don't know how to look after it and if you can't provide it with the space, food and possible companions that will help it live a healthy life. Don't take animals from the wild, unless they are ill and/or injured and you can protect them until a wildlife charity can help. It is cruel to take animals from their parents, especially if the parents will look for the babies, while putting their other babies at risk. You may be breaking the law by keeping wild animals or you may need a licence to look after some species. Please check with a local wildlife group. 2. Eggs: Please don't remove eggs from nests. The mother birds provide the right temperature for the eggs and won't sit on them if the temperature is warm enough for them to develop naturally. It is illegal to remove eggs of some species and, unless you have an incubator or a broody hen, the egg may not develop. If you are allowed to touch the eggs, you can candle them to see if they are fertile. If theys aren't fertile, they won't hatch. 3. Fights: Please don't ask about fights between different animals. These questions assume that individuals of two species fight each time they meet and that one species will always be victorious over another. This is untrue. There are cases where a live mouse has been fed to a venomous snake, bitten the snake leading to the snake's demise. 4: Diseases: Please ask doctors or other medical experts about diseases that you may catch from animals. I can't advise on how to deal with viruses, bacteria etc.
