I'm curious to know if there are any green wood hoopoes currently being held in captivity, either in private or public collections. I understand that there are a few of these birds in the United States, but I'm wondering if there are any others in other parts of the world. Additionally, I'm curious to know if the population of green wood hoopoes in captivity is considered sustainable, or if there are concerns about genetic diversity, inbreeding, or other factors that might impact the long-term viability of this species.
