Bomb

The Black Bird (or Bomb Bird or Kamikaze Bird) is a type of bird in Angry Birds. It is the second most powerful bird in the game, and is especially efficient in taking out stone structures. Although being extremely powerful, Black Birds are a generally placid species. Once angered however, the black bird will stop at nothing to get revenge.

The Black Bird has great physical strength, much like the Big Brother Bird. It's one of the rare Birds consistently capable of penetrating a concrete wall when aimed directly at it. It can also penetrate other walls pretty readily, but its overall penetrating power is tempered by its time-activated ability.

The Black Bird looks like a bomb, and that's precisely its ability. Once the Black Bird impacts anything, it glows red. About two seconds after doing so, the bird explodes, heavily damaging anything within a short radius and forcing back anything else within a larger radius. The Black Bird can also be made to explode early by tapping the screen or clicking the mouse.

Frankenstein Bird
Frankenstein Bird is a version of the Black Bird. He is a Halloween addition of Black Bird in the plush collection. He has two screws and stitches in his head and lower left parts of him.
