The Blue Birds (also known as the Cyan Bird, Light Blue Bird, Splitter Bird, Glass Jaw, Blue Ice, or Trio Bird) are a species of Birds in the  Angry Birds series. First debuting in Theme 1-10, these birds are the weakest of the eight, but have the unique ability to multiply into three identical copies to fly into the pigs and their buildings.

The bird can be used in two different ways. The first way is to multiply it when the player releases it to hit the targets in one time. The second way is to multiply it right before the bird crashes onto the building, to either break through ice or to push buildings down. They are strong at destroying glass blocks.

For the most critical damage to projectiles, tap the bird before hitting the structure, causing severe damage, especially to ice.
