Anatakitaki caves is a must see, when you are on Atiu. Embedded in tropical rainforest, this limestone cave with spectacular stalactites and stalagmites is untouched by any human infrastructure or safety measures. It also contains an underground pool, in which you can take a candlelit swim and is home to an absolutely unique bird (please go to the next blog entry).
Unique to Atiu, unique in its features: the Kopeka (Atiu swiftlet). This little bird, not weighing more than 13 grams, has some serious technical features. While it´s got perfect sight to find its way when there is light, it also is equipped with sonar. It lives in the Anatakitaki cave – where it is mostly dark – and navigates by issuing click-sounds, which reflect of the cave walls and structures. And please remember, we are talking about a bird here, not a bat!
