Hear a call. Name the bird. You're climbing Ruapehu, or walking through Abel Tasman, or camped somewhere on the coast... and something calls from the canopy. You stop. What is that? Koekoe trains your ear so you always know. HOW IT WORKS Listen to a real field recording, then pick the right bird from four options. Get it right and the card gets easier. Get it wrong and it comes back sooner. Over time, the 28 species in the app become as familiar as old friends. WHAT YOU'LL LEARN Tūī. Bellbird. Kōkako. Kea. Kākāpō. Grey warbler. Morepork. All 28 NZ native birds, including the rarer ones most people couldn't name. Learn to hear the difference between the cascading notes of a tūī and the liquid bells of a korimako.
