The Yellow Bird is a bird you play with in Angry Birds. The birds are yellow colored (hence their name) 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 go through several thin wood blocks.

Strangely, they are weak against Glass, despite glass having a much weaker strength than wood.

Trivia

 * Besides the Mighty Eagle, Yellow Bird is the only bird that's not in a circular shape.
 * When it turns into a Corpse, the Yellow Bird rolls even though it has flat sides.
