Corpse

In the Angry Birds universe, the term "Corpse" is used to describe the state a Bird goes through after they crash into an object on the board. In this phase, the Bird will appear badly wounded and injured, with dazed/black eyes and crooked beaks. This is also the time when the Bird's strength significantly decreases until it can no longer destroy blocks without the aid of motion.

It should be noted that Black Birds do not have a separate appearance after landing on a structure, as they just flash shades of red before exploding. The Big Brother Bird does not have a corpse sprite- it reuses his basic sprite, and the White Bird has two different corpse sprites, depending on if it's egg was dropped or not.
