1.They build their homes about 4.6m above the river,an important feature（特征） for the safety of the young.
an important feature指代的是什么?是前面一整句吗?可以这样指代吗?
2.Using these four claws,together with the beak,they can climb about in the bushes,looking very much like primitive birds must bave done.like在这边是当连词吗?后面怎么可以跟一个句子啊?

1.指代的逗号前的整句话,这里省略了which is,加上的话就比较好理解了.
2.后面那个不算是句子,must have done 是状语,修饰primitive birds用的,所以算是一个词组而已,翻译了就是“就像是原是鸟类必须要做的那样.”
