The only walkthrough exhibit in the park - an open wetland enclosure featuring Japanese cranes and snow geese.
Note: As the signage at Niendorf was horribly out-of-date (at almost all mixed-species exhibits, the signs mentioned species that clearly weren't there or failed to mention that species that clearly were there), I'll only note the species I saw and not the ones mentioned on the signs.
Yeah, a location by a swampy nature reserve certainly makes for some nice and economical exhibits for waterfowl. (But after a rainy day, it doesn't make for visitor-friendly footpaths...)
