Hornbills and Toucans exhibit

The aviaries are around 10 metres (30+ feet) high. In front of them is the monorail track.

Doesn't the monorail disturb these birds?

From what I've observed of hornbills and toucans both of these birds are flighty, highly strung and easily unnerved animals and I would imagine that this setup must drive them crazy.

@Onychorhynchus coronatus The monorail was decommissioned in 2012. There didn't seem to be any problems when the monorail was running though, with the hornbills regularly breeding in those aviaries.

@Zooish Interesting, glad its been decommissioned though.
