Polar bear

北极熊是地球上最大的陆地食肉动物，体重可超过700千克，分布于从加拿大到俄罗斯的北极海冰区。是高度特化的海洋哺乳动物，依赖海冰捕猎环斑海豹和髯海豹。是优秀的游泳者，能够横渡广阔的开阔水域。被列为易危种，因气候变化导致北极海冰迅速减少，种群正受到严重威胁。

紅額鸚鵡

红额鹦鹉（Cyanoramphus novaezelandiae）是一种具有鲜艳红色头顶和脸颊斑块的小型亮绿色鹦鹉，为新西兰特有种，栖息于从海平面到高山带的森林中。适应性极强，觅食种子、花朵、果实和昆虫。由于引入的捕食者（鼠类、白鼬、猫）威胁，在本土已濒危，但在无哺乳动物的近海岛屿上维持着健康种群。保育迁移和捕食者控制项目支持本土种群恢复。
