Anatidae Hybrids
The full hybrid index was compiled mostly using Bird Hybrids, eBird, and Avian Hybrids. Some hybrids listed by these sources don’t have photos or information online that I was able to track down, which is why many of these taxa don’t have individual sections in the guide dedicated to them. For these taxa without evidence, it's unclear if many of them ever existed or are even possible. Contributions for these taxa especially are extremely helpful, but information on nearly all hybrids is lacking so any information or media is important. If you notice any errors or have something to contribute please leave a comment or send me a message.
Compiling a list of all known hybrids with examples is difficult for several reasons. Obviously I'm not able to obtain permission to embed all media of these hybrids on a single web page/journal post. This means I'm relying on countless other sites to continue to host said media for the foreseeable future. This will inevitably lead to broken links and lost media. Uploading to sites like iNat and eBird can hopefully prevent this.
Key:
✅- Certainly or nearly certainly is produced in the wild
⏺- Likely can be produced in the wild
(Note: I'm not extremely familiar with the introduced populations of waterfowl in a lot of places, especially Europe, so take these icons with a grain of salt.)

Both birds above appear to be (close-to?) wild-types. See Bird Hybrids for more examples of wild-type Graylag x Swan Geese.

Comparison of the shape of the base of the bill. Note the flatter vertical appearance of both Swan Goose and Graylag Goose, and the more angular pushed-in shape of Canada Goose. Graylag x Canada Goose and Swan x Canada Goose hybrids tend to have an intermediate shape between these two.

Graylag/Swan Goose x Mute Swan (Anser anser/cygnoides x Cygnus olor)
Other names: Swoose
NOTE: I have decided not to separate Swan Goose x Mute Swan and Graylag Goose x Mute Swan due to the uncertainty of the identities of many domestic geese. As for the examples below, Jörn Lehmhus has said that as far as he knows all of these individuals' goose parents have been Graylag x Swan Goose. In other words all of the below individuals are Graylag x Swan Goose x Mute Swan.

NOTE: Pure American Black Ducks frequently show a slight green iridescence on part of their head (like this bird). Hybrids tend to show a significant amount of green. The presence of just a small amount does not necessarily indicate Mallard involvement.
Pure American Black Ducks frequently show a thin white border to the posterior edge of the speculum (like this bird). The presence of white in this area does not necessarily indicate Mallard involvement. Hybrids tend to show a more extensive white posterior border to the speculum. Hybrids also tend to show a white anterior border to the speculum.
Female pure Mallards frequently show an olive-colored bill (like this bird). Greenish bill coloration on the bill does not necessarily indicate American Black Duck involvement.
Pure American Black Ducks don’t tend to show truly white tail feathers, however edges of worn feathers can appear lighter than normal.
Beware: Male Mallards in eclipse plumage (as well as other molts/odd plumages) can get easily mistaken for this hybrid.

Gray x Chestnut Teal (Anas gracilis x castanea)

There are some presumed hybrids on Macaulay Library based on what seem to be the parents nearby, but the hybrids in question seem to appear phenotypically identical to Gray Teal to my eye. Could the Chestnut Teal not be a biological parent? I don’t know enough about this to suggest anything myself so one can come to their own conclusions.

Mandarin x Laysan Duck (Aix galericulata x Anas laysanensis)
This seems to be the most credible evidence for any hybrid involving Mandarin Duck. All other alleged Mandarin Duck hybrids that I've come across either don't have any credible evidence or, in the case of Mandarin x Wood Ducks, are just eclipse plumage male Mandarin Ducks. No other Mandarin Duck hybrids in the paper below seem to actually be Mandarin Duck hybrids.

This bird certainly has all three species in it. If I understand correctly, it is likely ((Snow x Bar-headed Goose) x Swan Goose) x (Snow x Bar-headed Goose). In other words: 37.5% Snow Goose, 37.5% Bar-headed Goose, and 25% Swan Goose.
