The Blue Birds are a species of Birds used in the Angry Birds series. First debuting on the the tenth stage, these birds are the weakest of the seven, but have the unique ability to multiply into three identical copies, which fly into the pigs and their buildings.

It can be used in two ways. The first way is to multiply it when you release 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. Due to their lack of strength, they are mainly designed to destroy ice blocks. However, it is a must to multiply it to provide a triple force for tighter braking the glass blocks or to push the whole building down.
