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.)

Barnacle Goose and hybrid offspring 10/17/20 from Sam Zhang on Vimeo.

Five backcrossed ((WHOS x TRUS) x TRUS) offspring (center) with Trumpeter Swan parent (left) and hybrid (WHOS x TRUS) parent (right).
https://macaulaylibrary.org/asset/37814191
Four backcrossed hybrid offspring ((WHOS x TRUS) x TRUS) with Trumpeter Swan parent (left) (same individuals as above).
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.
Videos, these individuals seem to be S. m. v-nigrum x Mergus merganser (a video in the comments shows one individual doing its courtship display.)

From my understanding these birds are the result of a pure Graylag Goose breeding with a tri-species hybrid. Something like Graylag x (Swan x (Bar-headed x Snow)) Goose. See their likely parents here.

Very good resource!!
Here's a useful for introduced waterfowl in Europe which have established populations. It should be of use to you :)
