Finally getting to posting this. And I apologize for the lengthiness on this post, but waterfowl are one of the most widespread families in zoos.
As per normal, no information older than June 2016 was used, additions and corrections welcomed. I expect this list will have a good number of edits. Taxonomy follows the current version of Handbook of the Birds of the World.
**Domestics: for the sake of space (and probably my sanity) I have not included domestics here. This mainly means domestic forms of Graylag Goose, Swan Goose, Muscovy Duck, and Mallard (including Call Duck, Indian Runner Duck, etc)**
**Wild Birds: In many cases, wild waterfowl make themselves at home on zoo ponds, generally because of the free food and safe environment. I have attempted to avoid listing species present but not a part of a facilities collection. I know a few zoos do list them. Thus the following species have been treated with caution: Ruddy Duck, Mute Swan, Canada Goose, Wood Duck, Ring-necked Duck, Northern Shoveler, Blue-winged Teal, Gadwall, American Wigeon, Mallard, American Black Duck, Northern Pintail, and Green-winged Teal. These species are indicated by a +/- by their holders.**
