13．On a recent field trip to the Kalahari Desert，a team of researchers learnt a lot more about honey badgers（獾）．The team employed a local wildlife expert，KitsoKhama，to help them follow the badgers across the desert．Their main aim was to study the badgers'movements and behavior．
"The problem with honey badgers is that they are naturally curious animals，especially when they see something new，"Kitso says．"That，combined with their unpredictable nature，can be a dangerous mixture．If they sense you have food，for example，they won't be shy about coming right up to you for something to eat．They're actually quite sociable creatures around humans，but as soon as they feel they might be in danger，they can become extremely fierce．Fortunately this is rare，but it does happen．"
The research confirmed many things that were already known．As expected，honey badgers ate any creatures they could catch and kill．The researchers were surprised，however，by the animal's fondness for local melons，probably because of their high water content．The team also learnt that，contrary to previous research findings，the badgers occasionally formed loose family groups，including the fact that female badgers never socialized with each other．
Following some of the male badgers was a challenge，since they can cover large distances in a short space of time．Some hunting territories（地盘）cover more than 500square kilometers．
Although they seem happy to share these territories with other males，there are occasional fights over an important food source，and male badgers can be as aggressive towards each other as they are towards other species．
As the badgers became accustomed to the presence of people，it gave the team a chance to get close to them without being the subject of the animals'curiosity--or a sudden aggression．It also allowed the team to observe more closely some of the others that form working associations with the honey badger，as these seemed to badgers'relaxed attitude when near humans．
