There were many different species including sun bittern; spangled cotinga and cock of the rock. One species of fruit crow as well. I don't think there was a bellbird labelled but I could be wrong. The bird house seemed less full of unusual species than last time I visited about five years ago. The shoebill appears to have left the collection as has the harpy eagle. Hope that is of help.
@AWP Pitangus sulphuratus? Sure? When I did my plan for visiting last summer (2017), with ZTL I listed Pitangus lictor. Much rarer than sulphuratus. This and Furnarius leucopus are the biggest rarities of the free-flight hall, that I unfortunately found closed, hence I missed these species :-(
During my visit, Trogon viridis (a female), Pyrocephalus rubinus (a female), Querula purpurata, Chiroxiphia caudata (both lone males) and Cyanerpes caeruleus (a pair) were in the glass-fronted enclosures previous to the hall. Not sure if they had their counterparts in the hall too...
@Kakapo This list is based on the signages in the Vogelhaus. The Lesser Kiskadee came in 2016 according to ZTL, so after my visit. Some species were in both the hall and the glass-fronted enclosures, at least the trogon and the fruitcrow, maybe some more.
