The Birdie Memory app works in augmented reality with the Birdie Memory birds. Where to find Birdie Memory Birds: - In the US book "Listen to the Birds" published by Norton Young Readers Books (North American birds) - In the French book "Ecoute les oiseaux" published by Albin Michel Jeunesse (European birds) The Birdie Memory app is designed to be used by anyone from the age of 5 up, and it is suitable for beginners as well as knowledgeable birders. By simply holding the phone in front of a bird, it comes alive and sings its song! The application has 2 different modes: • "Observation mode" lets you listen to all the birds, and the accompanying text provides simple and precise information about each bird • "Memory" mode consists of a game where you can test your observation and memorization skills. It includes various levels of progressive difficulty, and also teaches the reader about the sonogram, a sound visualization tool used by specialists as an aid to memorization.
