失傳的歌聲

當年輕的雄性攝政食蜜鳥離巢後,會透過聆聽年長雄性的歌聲學習鳴唱。因人類發展導致牠們九成的棲息地被破壞,野外只餘下約300隻,被列作極危物種。在難以遇到雄性長輩的情況下,很多幼鳥也只能學習其他雀鳥的叫聲。結果因唱錯歌而無法吸引雌性及繁殖,加速了牠們絕種的危機。

Young male regent honeyeaters will learn their songs from elder males after they leave the nest. 90% of their habitat is lost because of human developments; there are only around 300 of them in the wild now, and are listed as critically endangered. With such small population, young males are unable to meet other elder males, and ended up learning other birds’ songs. Singing the wrong song means females might not mate with them. Without breading, they are moving closer to extinction.
