Get each of the birds into a nest with no moves left. Click and drag a bird in the direction you want to move it. Each bird has a number on its head which shows how many moves it has left. You can make birds push other birds, which doesn't use a move for the bird being pushed. To win, each of the birds must be in a nest with 0 moves left (they'll be brown). Try to collect all 3 stars, too!
