At least as interesting as the BoP, at least in my opinion: the Bowerbirds. Australian members might smile at me mentioning these birds, but so far, I have seen them only in Cologne, Berlin and Dvur Kralove. Does anyone know more zoo husbandries and if so, which species?
And when talking about PNG birds: does anyone know an institution keeping pitohuis, especially the famous Hooded Pitohui? I heard rumours about Jurong keeping them once, but haven't been able to find out anything concrete so far.
@Ara: In regard to Touracos-yes.
