Zombie Island of Dr. Ned
There is a mission located in Jakobs Cove which involves killing zombified Bloodwings called Corpse Eaters and collecting the bloodwing eggs they drop. They attack much like rakk but are nowhere near as deadly as Mordecai's Bloodwing.

Borderlands 2
Handsome Jack captures Bloodwing during the events of Borderlands 2, and uses slag to mutate her; increasing her size considerably and endowing her with all 4 elemental effects. After weakening Bloodwing enough, Mordecai uses a tranquillizer shot, cleverly named "Tranquila Blood", on her. However, Jack then proceeds to detonate an explosive collar on Bloodwing. The death of Bloodwing sent Mordecai into a rage, and later a depression.

Later, in the credits, there is a sketch of Mordecai with a small bird that just hatched out of an egg. It's assumed to be a new Bloodwing.
