This is the call of a tree hyrax, a small, furry mammal that looks like a cross between a groundhog and a ground squirrel—minus the bushy tail.

这是一种树蹄兔的叫声，它是一种毛茸茸的小型哺乳动物，看起来像土拨鼠和地松鼠的杂交种——减去浓密的尾巴。

Each species of tree hyrax has its own unique call: due to their distinctive shrieks, Oates and an international team of researchers discovered a new species of the mammal.
