Straw ... Grass ... Same thing! xD

But if you get another one, they don't nessacarily lose your bond. Skittles and Sunny are long-lost lovers, but Sunny hasn't lost his training.
Even though they play, chirp, and bond a lot with each other, it totally depends on the bird if they choose to do the same with you.
