Animated Background

[xDiVX]

How can I make an animated background (for example like the one in angry birds)

What do mean like angry birds?

If you mean like the blinking eyes the have in the background, you can simply just add a few animated sprites on to your scene, if you mean the way background moves (i.e the mountains in the background scroll slower than the trees to give a depth effect) then you need to look into parallax backgrounds.

In the main menu, when you just enter the game, after the logos there is the main menu with a play button and a few more, the background is animated with birds that fly and stuff like that

Yeah just add a few animated sprites to the scene with path modifiers, or if your using Physics set the velocity on a body, the flying birds in the background of angry birds are pretty much the exact same thing as the birds you use in the game(I presume), characters that are just set on a path and added to the scene.
