Press Packer Beth loves all kinds of wildlife particularly bats. Bats sleep during the day so the only time you can see them is at night.
She went out on a bat walk at night and found out some interesting facts about the creatures. Here's her report.
"Last month I went on a bat walk, in Oxhey Park with a group who study the wildlife, in the area.
Bats are endangered species so they are protected by law. All British bats are insectivores which means they eat insects.
The walk didn't start until 9 in the evening. This is when it starts to get dark and the bats first start hunting for insects!

The bats hunt whilst they are flying in the air.
They scoop up little flying insects using their tail and flip them into their mouth.
We used bat detectors to find them.
Bat detectors are able to pick up the frequency of the sound waves that the bats use whilst they are hunting. This method is called echo location.
I was very excited when I saw the first bat! It was a Pipistrelle bat. They are the most common in England.
Pipistrelle bats are also the smallest bat in England. They are about the size of your thumb so it was really hard to see them.
I had loads of fun going out on the walk. By the time my mum and I got back we were very tired."
