I'll do a small showcase for Tierpark Berlin, so people get an idea to what they have to offer in this category:
Mammals:
@SivatheriumGuy - A
Polar Bear enclosure with lots of nice water, but not enough landspace.
@Philipine eagle - This fantastic recent exhibit is great mix for South-East Asian animals with the
Asian Small-clawed Otter counting here.
@Philipine eagle - This huge enclosure contains a large group of
Père David's Deer that tend to live in swamps.
@SivatheriumGuy - Most of the deer paddocks do not count, but one species that is sometimes referred to as
Indian Swamp Deer/Barasingha does.
Birds:
@Philipine eagle - This large aviary contains a ton of species that are relevant to the category.
Species:
Saddle-billed Stork, Yellow-billed Stork, Hamerkop, Abdim's Stork, Hadada Ibis, Meller's Duck, African Pochard, Red-billed Teal
@Philipine eagle - This large aviary is unique in its kind as not many zoos tend to exhibit Gulls in a large aviary or at all. There is also a small lake next to it.
Species:
African Grey-headed Gull, Black-tailed Gull, Grey Gull, Laughing Gull, Eurasian Oystercatcher, Scaly-sided Merganser, Smew, Bufflehead, Ferruginous Duck, Lake: Black-necked Swan, Rosy-billed Pochard.
@Philipine eagle - A nice Australian themed wetlands aviary.
Species:
Little Pied Cormorant, Straw-necked Ibis, White-faced Heron, Plumed Whistling Duck.
@lintworm - Tierpark has somewhat all species of Pelican spread out through the park.
Species:
American White Pelican, Australian Pelican, Dalmatian Pelican, Eastern Brown Pelican, Great White Pelican, Pink-backed Pelican, Spot-billed Pelican.
@twilighter American and Chilean Flamingo pond next to the Kamelwiese.
@SivatheriumGuy - There are some forested Crane enclosures scattered around the park. There is one african crane that counts in the infamous vulture aviary, but I'm not sure I can count it based on just the one species.
Species:
Black-necked Crane, Siberian Crane, Demoiselle Crane, Eastern Grey Crowned Crane, Red-crowned Crane, Western Black Crowned Crane.
Part two will arrive soon.
