Jason Sudeikis voices Red, aka "eyebrows", a hot-headed cardinal (one presumes) who frequently doesn't quite see eye to eye with his feathered flock around him on the island they all reside in, Bird Island. These non-flying birds think they are all there is in this world until the day that a ship drops anchor on Red's home, destroying it, making him an enemy but the other birds seem more friendly toward their new porcine visitors, not knowing that the fun and friendship they're ostensibly bringing is merely a ruse to get closer to grabbing their precious and delicious eggs from right under their beaks. Now it's up to Red to try to figure out how to save the eggs by getting his bird brethren to mount an attack on the porker stronghold before the swine have had their dinner.
