If it was any other category, it would have been Burgers for me but this time I went with Wroclaw. Now, of course Burgers has some impressive exhibits for basically everything they hold and some of Wroclaw's exhibits are on the small side but what prevents me from voting for Burgers is that for me, its collection is disappointing compared to what it could be. If it was a smaller zoo that had the same way of displaying ectotherms as Burgers, there would still be a debate; but in my opinion; one of the great zoos in Europe should have more diversity (although they have a great fish collection) when it comes to reptiles and more than 3 amphibian species. Collection should never be the only reason to vote, in my opinion, but Burgers ectotherm collection is disappointing (I'm not saying it's lame though ) and since I cannot find anything really compromising about Wroclaw, except for a few exhibits on the small-side; I'm going with Wroclaw.
If you actually look underneath the title of the poll "Ectotherms" you see when the poll closes/closed...
