The Yellow Bird is a bird you play with in Angry Birds.

The birds are yellow colored and are triangular in shape.

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 what block is struck and what angle it's struck, but in most cases, it can cut through many pieces of wood easily. Strangely, they're weak against Glass, despite glass having a much weaker strength than wood.
