There is a tutorial for each bird’s special ability that you can see when you add them to your flock for the first time. The effects for each bird are the same as in other Angry Birds games, but you’ll notice that Red has a new extra-fierce battle cry which can help knock down towers.
Chuck still works best against wood, while the Blues go through ice like it were butter. Matilda drops an egg bomb and launches herself in another direction, Bomb explodes on contact, and newcomer Silver loops to destroy stone. Terrence doesn’t need an ability. Just look at him – he’ll go through anything and everything.
