On the Trail of the Honey Badger
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,Kitso Khama,to help them locate and follow the badgers
across the desert. Their main aim was to study the badgers' movements and behaviour as discreetly(谨慎地)
as possible,without frightening them away or causing them to change their natural behaviour. They also
planned to trap a few and study them close up before releasing them.In view of the animal's 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 some-
thing new,"he 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 vicious(凶恶的).Fortunately this is rare , but it does happen."
The research confirmed many things that were already known.As expected,honey badgers ate any crea-
tures they could catch and kill.Even poisonous snakes,feared and avoided by most other animals,were not
safe from them.The researchers were surprised,however,by the animal'5 fondness for local melons,probably
because of their high water content. Previously researchers thought that the animal got all of its liquid require-
ments from its prey(猎物).The team also learnt that , contrary to previous research findings , the badgers
occasionally formed loose family groups.They were also able to confirm certain results from previous
research,including the fact that female badgers never socialised 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 cover more than 500 square kilometres.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 the chance to get up close
to them without being the subject of the animals'curiosity一or their sudden aggression.The badgers' eating
patterns,which had been disrupted,returned to normal.It also allowed the team to observe more closely some
of the other creatures that form working associations with the honey badger,as these seemed to adopt the
badgers' relaxed attitude when near humans.
What does Kitso Khama say about honey badgers?
A.They are always looking for food.
B.They do not enjoy human company.
C.It is common for them to attack people.
D.They show interest in things they are not familiar with.
