略

选项分析：

A选项：过去分词短语found only in the Western Hemisphere和现在分词短语 surviving through extremes of climate均做主句的伴随状语，在平行方面没有问题（详见功能平行）。但是，由于伴随状语的主语和其主句主语相同，在本选项中即，find和survive的主语均为hummingbirds’range，这在逻辑上是不正确的。被发现和存活的都是鸟，而不是鸟的范围。

B选项：Correct. 本选项在语法和逻辑上均是正确的。句末出现的their range extending from Alaska to Tierra del Fuego, from sea-level rain forests to the edges of Andean snowfields and ice fields at altitudes of 15,000 feet是独立主格结构。

C选项：本选项缺少谓语动词。

D选项：本选项主句具有两个主语，在语法上是不正确的，即：
Hummingbirds, found only in the Western Hemisphere and surviving through extremes of climate, their range extends
划线部分为插入语，extends拥有两个主语（两个黑体字）。

E选项：本选项中found和survive之间缺少连词。
