This game not only shows how good an observer you are, but also how well you know the birds in your environment, as each time you turn over a card, you'll hear the song of that bird. Improve your memory with bird sounds!
The game has different difficulty levels. The first level is easy, but will you be able to play through the most difficult level? If so, and you can already remember the bird calls, you can take part in the challenge where you have to recognise the birds by their calls.
