Yellowbird (2014)

Yellowbird lives in the ruins of an old house. He lacks the confidence to leave his home, no matter how much Bug, his labybird friend, tries to convince him to go out into the world. Attempts to toughen him up have had little success, so Bug seizes an opportunity that leaves Yellowbird unexpectedly finding himself the new leader of the flock that is migrating to Africa. Still, lacking faith in his own abilities and with danger and imminent failure lurking around every corner, our feathered hero is forced to either find the strength required to work with the team or bow out and stay hidden away forever.

Unfortunately the movie Yellowbird is not yet available on HBO Max.
