They had several of the cochoa. At least 2 and I think more.... With the cochoa there has been some breeding success in captivity and they are apparently not that difficult to get to breed because some even bred in mixed species rainforest halls. I don't know why they disappeared. Perhaps inbreeding because of very small number of founders or the breeding was to slow (small brood size) to be self sustaining.
Thanks for the info. I've been fascinated by them ever since San Diego got some over a decade ago. No one seems to know much about them, they're rarely seen in the wild, and they all disappeared in captivity. I first saw them in San Diego in 2003 and again in 2004 - I even watched them building a nest and feeding each other - and then they were all gone by a few years ago. I believe the last bird was at Miami, which I saw in 2006. I know they bred at San Diego, not sure about Miami.
In regards to the earlier question re: birds of paradise, yes, I have seen them in multiple mixed-species aviaries.
San Diego had Raggiana BOP in the Owens Rainforest Aviary along with countless other birds: various pigeons and doves, starlings, lories and lorikeets, White-breasted Woodswallow, Dollarbird, Black-faced Cuckooshrike, Helmeted Friarbird, Greater Racket-tailed Drongo, Crimson-breasted Oriole, mynahs, babblers, laughing thrushes, etc. Same for Miami and their Wings of Asia aviary (Raggiana with practically the same species as Owens Aviary)
San Diego also had their Glossy-mantled Manucode in the Parker Aviary with pigeons, doves, woodpeckers, Eclectus, Argus, etc.
Bronx also has their B's OP (Lesser and Red) with Golden-headed Quetzal, Great Argus, Pheasant Pigeon, etc.
There is nothing quite like seeing a fully-feathered male Raggiana flying around in an open-air aviary. I will never forget the first time I saw that at San Diego!
