White Birds, (also known as Pelican Birds, Bomber Birds and Egg Birds) are a species of Birds seen in Angry Birds and Angry Birds Rio. They have the ability to drop explosive eggs on Pigs. Despite being the second largest of the birds, White Birds have poor physical strength, although the eggs they deploy have decent power, though suffer from a short blast radius. Once the egg is dropped, the corpse then flies upwards 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. It's species resembles a chicken.

Trivia

Others say it's male as all of the other birds are of that gender, and there is a separate Female White Bird which shows a single White Bird clad in makeup.
 * White Birds are the only birds to have two different corpses.
