This is not well-known in Korea, but a private petting zoo named "Aniland" in Hwaseong City, Gyeonggi Province, has two male of Wilson's bird-of-paradise, a pair of Red bird-of-paradise and I don't know how many of them there are, but they also have Lesser bird-of-paradise.
You can see pictures of the Wilson and Reds on the this exhibition animal description page of the Aniland homepage. And you can see a picture of the lesser on this Naver personal blog.
Aniland is the only zoo in South Korea to have Bali myna as well as the Wilson and Red. But Most of the visitors there simply enjoy feeding the animals and are not interested in them. So Visitors there don't write in detail about the animals they saw, I don't know their bird-of-paradises are still alive.
