Silver Bird is a bird that is experience. He has a confidant and best friend known as the Azure Bird, and is a ninja before he discovered the Flock.
Silver Bird looks like an Ice Bird from Angry Birds Space except he is colored silver and has black eyebrows. He is also square so when he turns into a corpse, he rolls like a rolling cube.
He has the ability to speed up ninja style, slicing things along the way, especially Fruits. He locks on where you tapped and speeds up that way.
Little is known about the history of Silver Bird before the events of Angry Birds 2. It is known that he went through negative and rebellious ages, with a black-to-silver order of color, the negative age having black and the rebellious age having grey/gray.
He can cut through wood, glass, stone, fruits by speeding up ninja style towards the target and on.
