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. Once a corpse remains still for several seconds, it will disintegrate into the air.

However, a bird remain offscreen left or right while still flying, it will automatically disintegrate due to its inability to do anything.

It should be noted that Bomb does not have a separate appearance after landing on a structure, as he just flash shades of red before exploding, although Bomb's corpse sprite is only seen in Angry Birds Star Wars. Terence doesn't have a corpse sprite- it reuses his basic sprite but he does have one in Angry Birds Star Wars, and Matilda has two different corpse sprites, depending on if her egg was dropped or not. Bubbles also does not have a corpse sprite. After a few seconds while it is inflated, it deflates, (and flies away) and then disintegrates.

Corpses can also prove to be trouble to the player, as if a bird launches into a corpse, it will  have little to no effect on the structure, and if Matilda fires her egg onto a corpse, it will bounce off in another direction before it explodes. Thus it is advised to wait until a corpse disintegrates before launching another bird.

These corpse sprites are changed in Angry Birds Rio and Angry Birds (Google Chrome).

The Corpse Glitch
Main article: Glitches

A glitch can be performed when a bird's corpse sprite is replaced by another one when the bird is supposed to be a corpse. To perform it, have a bird fly in the air while using its ability. Fire a second bird at the first bird while the first one is still in the air, using its ability. If done correctly, the first bird's corpse sprite will be replaced by its ability sprite. The glitch can be seen by RovioMobile's Poached Eggs 3-12 on Youtube. Rarely, Hal doesn't have crooked beaks if it hits an indestructible structure, but remains opened.

Also, it can sometimes happen that, after Matilda has launched her egg, it will 'pop' back to its corpse used when she didn't use the egg. This only happens in Angry Birds, Angry Birds Rio and Angry Birds Facebook.

Also, if you fire Big Brother Bird and hit Boomerang Bird or Yellow Bird, their pain noises could be heard instead of Big Brother Bird's pain noises.

There is a glitch when you launch Blue Bird, and split them into three, they have their corpses.
