In the depths of the forest, families of various bird species live on several trees. Once, when the parents flew, the chicks got out of the nests and mingled with each other. Now in Birds LineUp you will need to sort them. Before you on the screen you will see wooden blocks on which the chicks will sit. They will all have different colors. You will need to examine everything carefully. With the help of the mouse, you can move the chicks to the right or left, as well as up or down. Performing these actions, you will have to expose one single row of chicks of the same color. As soon as you sort them you will be given points and you will move on to the next level of the Birds LineUp game.
