White Birds are a species of Birds seen in Angry Birds, Angry Birds Seasons, 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 and are therefore commonly overestimated in their effect on the structure. 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.
