The Yellow Bird (also known as the Maching Bird, Fast Bird, Woodpecker, Missile Bird, or Turbo Bird) are a species of birds in the Angry Birds series. Their ability allows them to pick up speed to cause the most possible damage to the pigs and their structures. Much like many of the other birds, its strength usually varies depending on the block and angle that is struck, but in most cases, it can cut through many pieces of wood easily. Strangely, they're weak against ice, despite ice having a much weaker strength than wood.

The Yellow Bird is most useful when used first.When it's first,hit the area with the most wood.Doing this usually knocks down the structure.
