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 contact me (liliumbirder@gmail.com).
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 website. 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 iNaturalist and eBird can hopefully prevent this.
Each genus within Anatidae has a corresponding page on this site. Intergenus hybrids are assigned to the page corresponding with the first genus chronologically that they are comprised of (using the eBird/Clements 2024 taxonomy). Hybrids between more than two species receive their own page.
