I'm new to this discussion but I just read all 55 pages out of interest. Such an impressive lists!
@Giant Eland probably knows how much I hate him for that, haha!
I know this is an old comment, but I just wanted to inform you that the captive population is not really
Ducula pistrinaria. The original birds are hard to trace back but they are most likely a subspecies of
Ducula aenea. My bet is on
sylvatica.
Considering the fact that I'm only doing this for a few years, here are a few examples of rare species that most of you will probably not have seen before. I know these are random, not mammals only, but I would be very interested in seeing how many you guys have. I chose 50 random and less occurring species, all of them were photographed in captivity.
