Is the king of Saxony bird of paradise in any collection?
what about the blood pheasant?
Fan-throated lizards?
Hoatzin?
King-of-Saxony is not kept.
I don't think there's any Blood Pheasant in public collections at least. Maybe privately but few if any.
The lizards wouldn't surprise me, though I can't find any confirmation currently.
Hoatzin has been kept historically, the only place that might have them currently is National Aviary of Colombia. I believe the bird they had has since died, another may have turned up in the meantime but I wouldn't count on it. The species just doesn't do well long-term in captivity.
