I suspect that anything that is said about the Alfred Brehm will not sway anyone's perspective. I love it (or loved it - I've not yet seen the on-going changes); others loathe it equally strongly, Their views are wholly valid (but obviously I don't agree with them).
This is absolutely stunning to me. I happen to like (I will not go as far as to say love) the ABH in its old version. Much of it has to do with the way the complex was handled and utilized by the staff. The house itself for all I care may not be changed any more but the outside enclosures should. That does not affect the house which I would like to keep as is. So I am with Sooty on that one.
The Sun Bear House is pretty horrible - but I wonder if it's any more horrible than most zoos' (unseen) inner dens. The external cage is small, but just about (at a pinch) adequate.
The sun bear house is not a bear house, it is a great apes house of the late 70s. And as such it is in fact much better than much of indoor housing I have seen throughout zoos in Europe of which I have personally seen approx. 90%. You just do not get to see those 'enclosures' on a regular basis. And by the way, even Burgers back housing is worse than Berlin TP. The problem again is the outdoors of which I don't necessarily mind the 'cage' itself but the size and the height. Triple the width and length (which is there) and triple the height (which should be a no brainer) and put some structure in it and you have maybe an ugly 'cage' still, but an enclosure that would fit the needs of sun bears way more than fancy spacey outdoors with non durable climbing structures that on top of that do not supply what is needed most - semi shade. That being said, the complex is totally outdated and should not be any more.
The enclosures of the spectacled bears and polar bears I personally consider to be subpar for one reason only: they cannot be separated, and if the zoo is breeding, this works to the detriment of the male bear. Unless you have a decent holding enclosure for the male bears in a breeding situation - it is a no go for me. Same with the black bears ( I have been inside the outdoors enclosure of the fishbowl enclosure and the street noises do not penetrate to the inside).
The polar bear enclosure in Rotterdam is actually the dumbest thing ever built for money they spent, especially given the money that went in the glassed pool-indoor thing in relation to what could have been built for that money outside instead. But they have an option to house a male bear separate from a female with cubs.
The hyenas in Rotterdam have a fine enclosure. The tiger enclosure is great.
On numbers Berlin TP wins.
I have lived in Berlin, the TP is most likely the zoo I like best (and yes in my book the Tierpark totally wins against the Zoo).
I admire the devotion and stamina that the care takers in Berlin do their jobs with and their professional knowledge.
I am sad and mad at the same time that this gem most likely will end up in shambles, because it never has and never will get the financing that it would need to out-do its counterpart in the western part of Berlin. And all that was great and should be kept (the SUN BEAR LEGACY for crying out loud - I am a single issue voter on that and they are ending sun bears in Berlin) will disappear, all for the TP being just another run of the mill zoo; a geo zoo theme park thing for that matter.
Rotterdam was in that very same situation (I believe) and they turned it around. Everything they did came out better than before, they even got Pierre Gay in for their Okapis...
So, here was my eulogy for the TP

and my vote goes to Rotterdam. I cannot believe I am actually voting against my favorite zoo, but what is was then and is now, will not last. Even if they have a surviving polar bear cub next year.
