The Big Brother Bird, (also known as the Fat Red Bird, Juggernaut Bird, A380 Bird, Big Red Bird, Power Bird, Big Lori Bird, or Ogre Bird) is one of the several birds in Angry Birds. It's described as the larger counterpart to the Red Bird, having much more strength. If is tapped/ clicked while moving, it will result in a big whine. However it's more powerful than his little brother/ Red Bird

Big Brother Birds are first introduced in the episode The Big Setup and are used for the majority of the episode, starting from Theme 9-1. It's the only bird that can easily smash through about one block of concrete, and it doesn't need a special ability to smash through all types of obstacles. Instead, it uses its weight to crush through objects. However, his strength varies depending on what block(s) he's used on, as a large square block will almost always stop the Big Brother Bird in its tracks.

Although having a large brain, the big brother bird is the least intelligent of all the birds. The Big Brother bird only knows to hate pigs and to protect the smaller birds, as seen in the ending to Season's Greedings. He's seen as their protector. Some people even believe it may be the other birds guardian, even if he isn't.
