Pata Zoo In Bangkok, Thailand

One thing which is rarely mentioned and I don't know why it is that I never noticed it before but there is a third 'zoo' floor. This is not open to the public but from odd angles I was able to see and/or hear other hornbills and primates up there.
The boardwalk through walk through aviary is in urgent need of attention. Like the rest of the zoo you can only patch up for so long before something really goes wrong.
I suppose my problem is that I have seen some really appalling zoos and if I include them into any formula of how to gauge the zoo then Pata Zoo is nowhere near the bottom. Some zoos which Joe public would be inclined to marvel at would be much nearer the bottom with me. Okay the location is far from ideal but I can remember Blackpool Tower Zoo, Harrods Zoo and others in Department Store zoos in Grimsby, Leeds and other places. I also remember the Associated Pleasure Parks 'Winter Zoo's' in Kelvin Hall in Glasgow, Newcastle Town Hall and in Leeds. Some of these were worse than Pata Zoo.
