The Big Brother Bird, (also known as the Fat Red Bird, Juggernaut Bird, Big Red Bird or Ogre Bird) is one of the several birds in Angry Birds. It is described as the larger counterpart to the Red Bird, having much more strength. It is the strongest of all the Birds, rivaling that of the Black 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 is the only bird that can easily smash through about one block of concrete, and it does not 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 is 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 is seen as their protector. Some people even believe it may be the other birds parent.
