Ah, I actually 'reread' the three pages in this thread, but obviously not very well. Why did they leave?
The Guereza left the zoo to be replaced by King colobus, 4 males arrived recently from Poznan (originally from Blackpool), as Poznan will start a breeding group.
Another new mammal addition are 1.1 Nile lechwe from Hodenhagen, which live in the former Bukhara deer enclosure, which has seen the soil being completely replaced after the Deer left after issues with TB.
The last remaining Balabac mousedeer left for Wroclaw. The zoo is temporarily without tigers as well, as the enclosure is being renovated, the remaining male went to Schwerin.
