In Anthony Sheridan's latest zoo book, Zooming in on Europe's Zoos, he has crammed a tremendous amount of information into almost 500 pages. Approximately half of the book is a series of glossy profiles of 115 major zoos (2 pages on each) but there is still another 25 chapters of information that almost reads like a separate publication. At the back of the book are his controversial ranking lists and several pages of "interesting zoo facts" that include attendance numbers. In regards to his personal, obviously subjective ranking of zoos he offers little explanation as to his choices, but there is an entire page devoted to explaining how he comes up with all of his attendance figures and it appears that he adheres to an accurate portrait of the popularity of each zoo. Here are the 35 most popular zoos in his book: Berlin - Germany - 3.3 million annual visitors Vienna - Austria - 2.5 million annual visitors Stuttgart - Germany - 2.25 million Munich - Germany - 2 million Wroclaw - Poland - 1.95 million Basel - Switzerland - 1.95 million Leipzig - Germany - 1.9 million Pairi Daiza - Belgium - 1.8 million Hamburg - Germany - 1.7 million Cologne - Germany - 1.65 million Chester - UK - 1.6 million Arnhem - Netherlands - 1.45 million Rotterdam - Netherlands - 1.45 million Zurich - Switzerland - 1.425 million Karlsruhe - Germany - 1.4 million Hanover - Germany - 1.35 million Amsterdam - Netherlands - 1.35 million Prague - Czech. Rep. - 1.325 million London - UK - 1.25 million Berlin Tierpark - Germany - 1.2 million Copenhagen - Denmark - 1.15 million Beauval - France - 1.15 million Barcelona - Spain - 1.15 million Loro Parque - Spain - 1.125 million Dublin - Ireland - 1.1 million Budapest - Hungary - 1.1 million Nuremberg - Germany - 1.075 million Paris - France - 1 million Duisburg - Germany - 1 million Madrid - Spain - 1 million Osnabruck - Germany - 995,000 Rhenen - Netherlands - 995,000 Planckendael - Belgium - 950,000 Munster - Germany - 950,000 Colchester - UK - 930,000 Conspicuous by their absence would perhaps be Moscow (maybe Russia is not "European" enough for Sheridan?) and Lyon (a free zoo in France). Other zoos that failed to make the cut are Frankfurt (910,000), Gelsenkirchen (900,000), Antwerp (890,000), Kristiansand ((880,000) and Dresden ((850,000) in the slots #36-40. Has anyone on ZooChat visited ALL of these zoos? I've personally toured the 35 most popular zoos in the United States and I'm wondering who would be the "Snowleopard of Europe"?
