@zooboy28 I suspect that is likely. The other possibility would be from a US zoo. I would be interested to hear from anyone who knows anything about the origin of these birds.
Can't help with origin much, but they are kept in three US zoos- Prospect Park, Houston, and Miami. Prospect Park has the most sizable amount, with 3.5. I suspect that's where they'd have come from if they did come from America.
Edit: I doubt they did come from America, though, as we don't really have that many to spare regardless.
