The Big Brother Bird is a large red bird from the Angry Birds series.

Angry Birds
Big Brother Birds are first introduced in October 2010 in The Big Setup. It doesn't have a corpse or special ability, instead, its big bulk crashes into an object.

Angry Birds Seasons
Big Brother Birds first appeared in Trick-or-Treat in Angry Birds Seasons. In the video for Seasons Greedings, it's seen as the birds' protector. Big Brother Birds act as same as before.

Angry Birds: Rio
A Big Brother Bird appeared on a wallpaper before appearing in Airfield Chase. In Airfield Chase, it's flung with its mouth opened and eyes closed, like most birds.

Trivia
Like the Red Bird, it squawks when you tap on the screen.
