On the Trial of the Honey Badger
On a recent field trip to the Kalahari Desert,a team of researchers learn a lot more about honey badgers.The team employed a local wildlife expea Kitso Khama to help them locate and follow the badgers across the desert.Their main aim was to study the badgers,movements and behavior as discreetly(谨慎地)as possible without frightening them away or causing them to change their natural behavior.They also planned to trap a few and study them close up before releasing them in view of the animals reputation;this was something that even Khama was reluctant to do.
The problem with honey badgers is they are naturally curious animals,especially when they see something new,he says.That,combined with their unpredictable nature.can be a dangerous mixture.If they sense you have food,for example,they wont be shy about coming right up to you for something to eat.Theyre actually quite sociable creatures around humans。but as soon as they feel they might be in danger,they can become extremely vicious(凶恶的).Fortunately this is rare.but it does happen.
