Interesting combination! I don't think I've seen these two species housed together, but they are both Asian species (even though their ranges don't overlap). If the Green Peafowl don't bully the Demoiselle Cranes, then it seems like a good pairing!
@Summer Tanager It seems to me that the two species have been together for some years now. What's more, the cranes seemed to be in good condition, so the combination must work.
@Gab_1 That is great news! Green Peafowl are so big and Demoiselle Cranes are so small that I thought the cranes might be at a disadvantage. The large aviary may help the situation and it's great to hear and see that this combination works!
