White Birds(also known as Egg Beater, Egg Bomber or Awesome Bird) are a beast species of birds seen in Angry Birds, Angry Birds Seasons, and Angry Birds Rio. They have the power to lay egg bombs on Pigs. Despite being the second largest of the birds, White Birds are weak in physical strength, although the egg bombs they deploy have decent power, though suffer from a short blast radius and are therefore commonly overestimated in their effect on the structure. Once the egg is dropped, the corpse then flies up and explodes to the right. Additional damage can be done to the fortresses if the egg is dropped in such a way that it launches the corpse into the structure. The White Birds' physical appearance seems to be based on an egg shape. The white bird is based upon the Snow Bunting.

Trivia

 * The White Bird is most likely firing a egg bomb as:
 * 1) It explodes, while if it were real and the bird dropped it would break,
 * 2) Eggs can't be dropped every time the bird is firing. Eggs take time to drop. Usually within a day or two.
 * White Birds are the only birds to have two different corpses.
 * White Birds are also the only birds to have projectiles, if the Blue Bird's multiple beings aren't counted.
 * Despite the fact that the birds are angry about their poached eggs, the White Bird fires eggs . This is more evidence that the White Bird is firing fake eggs. The other evidence is on the 2nd and 3rd part of the trivia.
 * According to this official wallpaper, the White Bird is a chicken.
 * There is a glitch where the white bird will swell up after firing the egg bomb.
 * In Angry Birds Rio, the White Bird's entire sprite sheet changed.
 * An additional glitch in using white bird. When you drop thepoot exactly where a corpse of another bird or a non-corpse bird sitting on a slingshot is located, you'll be able to see the egg for a few moments.
 * For some reason, in the Summer Pignic promo video, when the Boomerang Bird knocks the slingshot over to a certain angle, you see a White Bird fall to the plain in the background, and it explodes, just like the Black Bird, instead of dropping the egg, and flying farther, although, it could have dropped the egg at the same time it landed.
