My thoughts exactly even though I think that the Asian black is the one that needs improvements the most. The Malayans actaully have decent exhibits even though they are a bit old.
Wasn't this enclosure originally for Polar Bears? There were common Seals in it last time I was in Cologne. The Sealions have a separate pool from this complex of enclosures that has an old artificial rockwork 'spire' in the centre.
The other sealion pool is still there. There are historical displays for this pool that show seals and sealion together going through some pretty weird training.
After the deat of the asian black bear the sunbears have now 3 enclosures next to each other. So why bring one or two of them into a enclosure what don't have a indoors, cause it was broken down for a quarantaine long ago?!
