The best we've come up with is that he delivers the cage, other doodads, and a note in the cage saying mom and dad have to get the bird. Or instead of a note, a fake gift card from Santa. (Additional info: he's an only child, 6 years old, and flies off to the grandparents the day after Christmas, staying there for 3 weeks. The bird is cockatiel)
Curious George: Santa hacks. What's the best way for Santa to give a bird as gift?
