The black swans and gooses certainly are. The cormorants are now within the Greater Sunda aviary.
Both the doves and lesser adjutant can freely roam across TMII. The single stork more often roam the large lake in front of the Indonesian Soldiery Museum (Museum Keprajuritan Indonesia). Wild Lesser Adjutant + Museum - ZooChat
@Rizz Carlton I'm surprised they're chill with one of their larger birds roaming around outside of their park. But since personal cars and other fossil fuel-based vehicles aren't allowed in the TMII premises anymore, chances of becoming a roadkill is pretty low.
