Brown Bird is an all-new bird from Angry Birds 2: The Pigs' Revenge.
Brown Bird has the ability to spit acid from his beak, which can go through pigs, wood, glass, ice, stone, TNT, and any other material you can think of. You can upgrade him later to Super Brown Bird, and he spits acid 5 times more powerful than the normal acid. The ugrade costs real money, though.
- This is not the first Brown Bird, Chewbacca Bird was.
- It is believed that Borwn Bird is Red Bird's half-brother, since they have the same shape and size.
