I don't expect the birds to last very long. They are made with clay after all. True enough, Kai dropped the red bird shortly after I handed him the bird. Red bird fractured his tail feathers (i.e. the tail feathers broke away from the body). He cried and we had to send the bird to the ER doctor -- Terence -- immediately. Terence glued it back, and it is now recuperating in the hospital -- Kai's bookshelf.
I'll keep you posted of its progress.
