Bomb

The Black Bird (also known as the ​Kamikaze Bird, Stone Smasher Bird, Best Bird, Fire Bird, Smoke Bird, Strong Bird, or Bomb Bird) is a species of bird in Angry Birds. It is especially efficient in taking out stone structures. Although extremely powerful, it does not seem to be able to control his anger. Whenever he is angry, he turns red and explodes.

Overview
The Black Bird has great physical strength, much like the Big Brother Bird. It is among one of the 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 hits 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.

Trivia

 * Black Bird is the only playable bird without a tail. But it does have one in Knock on Wood and early Plush Toys.
 * The Black Bird is the first bird to not have a corpse sprite.
 * In the Wreck The Halls promo, Black Bird blew itself up because of anger; but when seen skiing with Red Bird, he is smoked from the blast. This proves that the Black Bird doesn't die if it "explodes".
 * On any genuine Angry Birds media except the game, the Black Bird doesn't have its white spot. Early versions of the plush toy did, but were redesigned later.
 * The Black Bird is based upon the Greater Antillean Bullfinch/Crow.
 * In the Wreck the Halls promo, before the Black Bird explodes, his head feathers come downwards unlike in the game.
 * The Black Bird is the only bird with crossed eyes.
