I also visited Wisbroek and did manage to talk to the manager. They currently house : King bird of paradise Red bird of paradise Lesser bird of paradise Greater bird of paradise (mainland and aru island subspecies). From what i gathered the birds came from Al wabra in Qatar. Which would make sense as it is the largest collection of birds of paradise with more than 120 individuals and the only place in the world that breeds them with any consistency. Wisbroek housed at least 1.2 of each bird of paradise species.
