I'm not certain about the main characters in this story. But if it's a traditional Christmas - themed story, it could have characters like Santa Claus in addition to the blue bird. Santa might cross paths with the blue bird and they could have an interesting interaction. There could also be some elves who play a role in the story, perhaps helping the blue bird or being part of its journey during Christmas.
Since I don't know the exact 'Blue Bird Christmas Story', it could be the blue bird itself as the main character. There might also be some humans like a kind old man or woman who befriends the blue bird.
Not having read the 'Blue Bird Christmas Story', I can only speculate. The blue bird is surely a main character. There could be a family living in a small cottage near a forest where the blue bird lives. The family might consist of a mother, father, and a couple of children. They notice the blue bird during Christmas and try to help it when it's in trouble. The children could be especially curious about the blue bird and form a special bond with it, making them all important characters in the story.
