Unlike most warbler species, the male and female blue-winged warbler are very difficult to tell apart.

>>>> I chose (B), which I considered more concise than (E)...But how come the answer is (E) ?? Could anyone explain this to me, please?

A：unlike前后一个是群体（species），一个是个体（warbler），所以是不对的。
B：unlike前后一个是species，一个是gender，没法比较。
E中unlike前后都是群体性质的，所以正确
