The Yellow Bird (A.K.A. Maching Bird, Canary Bird, Fast Bird or Speedy Bird) are a species of birds in the Angry Birds series.

Their triggerable rush 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. The yellow bird has a particular strength against wood obstacles, able to penetrate several walls easily particularly with help from its abililty. Strangely, they're weak against glass despite glass having a much weaker strength than wood.
