all wiped out when the forests burned. 森林被烧毁时 全部灭绝

113. otherwise known as the birds.
     又名“鸟类”
114. Before the apocalypse,
     在大灾变之前
115. there had been hundreds of ancient species living in the trees,
     树上居住着数百种古老的物种
116. all wiped out when the forests burned.
     森林被烧毁时 全部灭绝
117. But a handful of ground-dwelling birds did make it through.
     但少数栖息在地面上的鸟类 幸存了下来
118. These survivors were kept warm by feathers...
     这些幸存者靠羽毛保暖
119. and were self-sufficient from their first breath...
     一出生就能自给自足
