Birds known as honeyguides exhibit a unique pattern of behavior: the bird leads another animal, such as a honey-badger or a human, to a bees’ nest with their chattering when they fly ahead; after the larger animal takes honey, the bird eats the wax and bee larvae.
with their chattering when they fly
with chattering and its flying
by chattering as it flies
by chattering and its flying
by chattering as they are flying
原文意思：一种鸟有一种独特的行为，它用chatter这种方式把人引导一个地方当它飞的时候，大动物拿走蜜它吃剩下的
题目分析：A中they应该指鸟，但是鸟在前面是单数，用they不行，杀。B用and ，fly和chatter无法在语义上形成并列关系，杀。C说当它飞的时候，语义合理，留着。D和B的错误类似，干掉。E又用they，干掉。
